Accurate and efficient object detectors on resource-constrained edge devices are essential for real- time space applications such as satellite monitoring and deep sky exploration. However, Deep Learning (DL) models face difficulties when implemented in environments with limited memory and computational capabilities. To address this problem, this study proposes two lightweight architectures based on YOLOv10s and YOLOv10n that integrate ShuffleNetv2 and MobileNetv2. The Shuffle architecture improves efficiency by taking the advantages of the depthwise separable convolution and channel shuffling. The Mobile-Shuffle architecture combines Shuffle blocks with MobileNetv2-inspired blocks to enhance feature extraction and representation while maintaining low computational cost. This work evaluates both architectures on the augmented DeepSapceYOLODataset dataset, which contains a collection of annotated deep sky objects with different sizes and complexities. The evaluations demonstrate that the Shuffle architecture achieves the highest mAP50 on both sets, the fastest inference speed, and the smallest model size, especially in YOLOv10s architecture. While the Mobile-Shuffle architecture shows its strength in the YOLOv10n variant by improving the detection accuracy, it comes at the cost of the increased inference latency. These findings demonstrate that the proposed models offer a practical trade-off between accuracy, speed, and size, making them well-suited for edge deployment in space-related scenarios.

Abstract This paper proposes a hybrid approach integrating the expert knowledge judgment approach using the Cognitive Pairwise Comparison (CPC) to the Deep Learning, a modern classification approach, for astronomic object classification. The astronomic data with ten thousand samples retrieved from Sloan Digital Sky Survey Sky Server Data Release 15 (SDSS SkyServer DR 15) are used for this study. The CPC is an approach to elicit and encode expert knowledge in the format of a Pairwise Opposite Matrix (POM) to evaluate expert preferences for the features. A forward feature selection algorithm taking the expert choices using CPC for the ordered features is used for the feature selection for the deep learning algorithm to build a heuristic training model based on the astronomic data. Whilst the accuracy of the case of improper feature selection is just 37.1%, the proposed hybrid approach can obtain a very high accuracy of 97.9% for the classification of the astronomic object using the eight scaled features ( u, g, r, i, z redshift, ra, dec ). To extend this research, the proposed CPC can be used as a human-centered tool to be applied to other areas of data sciences.

Among the finds from KV 55 recently exhibited in Munich and then returned to the Egyptian Museum in Cairo there was an inlay fragment of the 'sky'-sign, slightly convex, in deep blue glass, adorned with yellow stars. The coffin may be ruled out. Only one 'sky'-sign was inserted at the end of the inscription and the inlay is still visible. It is made of deep blue glass without stars. This object was previously published by Reeves, and the authors' have commented on its possible original location in tomb KV 55. The possibilities are: a) the coffin, b) an unknown or destroyed object from KV 55, c) the canopic jars. It is clear that if the deep blue sky from KV 55 actually belongs to one of the canopic jars, then Dodson's theory falls short. Keywords: canopic jars; coffin; deep blue sky; tomb KV 55

The effective classification methods of the small target objects in the no-fly zone are of great significance to ensure safety in the no-fly zone. But, due to the differences of the color and texture for the small target objects in the sky, this may be unobvious, such as the birds, unmanned aerial vehicles (UAVs), and kites. In this paper, we introduced the higher layer visualizing feature extraction method based on the hybrid deep network model to obtain the higher layer feature through combining the Sparse Autoencoder (SAE) model, the Convolutional Neural Network (CNN) model, and the regression classifier model to classify the different types of the target object images. In addition, because the sample numbers of the small sample target objects in the sky may be not sufficient, we cannot obtain much more local features directly to realize the classification of the target objects based on the higher layer visualizing feature extraction; we introduced the transfer learning in the SAE model to gain the cross-domain higher layer local visualizing features and sent the cross-domain higher layer local visualizing features and the images of the target-domain small sample object images into the CNN model, to acquire the global visualizing features of the target objects. Experimental results have shown that the higher layer visualizing feature extraction and the transfer learning deep networks are effective for the classification of small sample target objects in the sky.

We develop a new method for estimating and removing the spectrum of the sky from deep spectroscopic observations; our method does not rely on simultaneous measurement of the sky spectrum with the object spectrum. The technique is based on the iterative subtraction of continuum estimates and Eigenvector sky models derived from Singular Value Decompositions (SVD) of sky spectra, and sky spectra residuals. Using simulated data derived from small telescope observations we demonstrate that the method is effective for faint objects on large telescopes. We discuss simple methods to combine our new technique with the simultaneous measurement of sky to obtain sky subtraction very near the Poisson limit.

Accurate segmentation of the sky region is crucial for various applications, including object detection, tracking, and recognition, as well as augmented reality (AR) and virtual reality (VR) applications. However, sky region segmentation poses significant challenges due to complex backgrounds, varying lighting conditions, and the absence of clear edges and textures. In this paper, we present a new hybrid fast segmentation technique for the sky region that learns from object components to achieve rapid and effective segmentation while preserving precise details of the sky region. We employ Convolutional Neural Networks (CNNs) to guide the active contour and extract regions of interest. Our algorithm is implemented by leveraging three types of CNNs, namely DeepLabV3+, Fully Convolutional Network (FCN), and SegNet. Additionally, we utilize a local image fitting level-set function to characterize the region-based active contour model. Finally, the Lattice Boltzmann approach is employed to achieve rapid convergence of the level-set function. This forms a deep Lattice Boltzmann Level-Set (deep LBLS) segmentation approach that exploits deep CNN, the level-set method (LS), and the lattice Boltzmann method (LBM) for sky region separation. The performance of the proposed method is evaluated on the CamVid dataset, which contains images with a wide range of object variations due to factors such as illumination changes, shadow presence, occlusion, scale differences, and cluttered backgrounds. Experiments conducted on this dataset yield promising results in terms of computation time and the robustness of segmentation when compared to state-of-the-art methods. Our deep LBLS approach demonstrates better performance, with an improvement in mean recall value reaching up to 14.45%.

Sea-sky-line detection plays an important role in the field of maritime object detection and unmanned boat. The traditional sea-sky-line detection method mainly starts from the direction of edge detection, and has poor applicability to the complex and changeable sea surface environment. In this paper, the deep-learning object detection method is introduced into the field of sea-sky-line detection. Through the lightweight improvement of YOLOv5 network and the replacement of its backbone network with MobileNet network, a sea-sky-line detection method based on the improved YOLOv5 algorithm is proposed and verified on the self-built dataset. The experimental results show that the proposed method can be applied to sea-sky-line detection in various scenarios. Compared with the traditional sea-sky-line detection algorithm, the proposed method has higher accuracy and stability, and has good portability and real-time performance compared with the original YOLOv5 network.

The positioning accuracy of optical fibers directly affects the observation efficiency of spectroscopic survey telescopes. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) adopts an optical fiber closed-loop positioning system based on a photogrammetric measurement system. A photogrammetric measurement system requires accurate identification of the optical spot position to achieve higher optical fiber positioning accuracy. However, the temperature difference within 1 day of the barrel of LAMOST will reach 40°C during the observation period. The change of air refractive index will lead to nonlinear deviation of the light propagation path of the optical spot, which will lead to the dispersion of the optical spot and cause a huge deviation in the position detection of the optical spot. To address this issue, we propose incorporating an automatic focusing system into the optical fiber closed-loop positioning system. Because each LAMOST’s fiber view camera (FVC) covers a field of view with hundreds of 320 μm-diameter optical fibers, fast and efficient focusing control for a large number of tiny optical fiber targets is highly challenging. Our solution implements a passive autofocus architecture combining an efficient image clarity evaluation method with a rapid focus search algorithm. Existing image sharpness evaluation methods are incompatible with FVC raw optical spot images, and traditional hill-climbing-based focusing algorithms require dozens of adjustments, significantly reducing efficiency. Our approach introduces an adaptive method for evaluating high-resolution optical spot image definition using the mean variance of the optical spot region, significantly reducing computational cost while improving threshold adaptability. Furthermore, we developed a focus search algorithm based on a hybrid convolutional neural network and recurrent neural network architecture. The algorithm predicts defocus distance from optical spot state sequence, achieving 95% single-shot focusing accuracy within the depth of field. It has been successfully applied to the LAMOST’s FVCs and also offers new methods for other focusing search methods based on passive autofocus for cameras.

We present a method to perform automatic image recoloring based on the distribution of colors associated with objects present in an image. For example, when recoloring an image containing a sky object, our method incorporates the observation that objects of class 'sky' have a color distribution with three dominant modes for blue (daytime), yellow/red (dusk/dawn), and dark (nighttime). Our work leverages recent deep-learning methods that can perform reasonably accurate object-level segmentation. By using the images in datasets used to train deep-learning object segmentation methods, we are able to model the color distribution of each object class in the dataset. Given a new input image and its associated semantic segmentation (i.e., object mask), we perform color transfer to map the input image color histogram to a set of target color histograms that were constructed based on the learned color distribution of the objects in the image. We show that our framework is able to produce compelling color variations that are often more interesting and unique than results produced by existing methods.

Deep CCD images were obtained for the object UGC-A86, an object identified on the Palomar Observatory Sky Survey, and listed in the Addendum of the UGC. Two objects are revealed at this location: perhaps a chance superposition in the sky of two galaxies at different distances or two interacting galaxies, or two components of the same galaxy. The brighter component is well resolved into stars, and a color-magnitude diagram has been obtained for it. Interpretation of the color-magnitude diagram is somewhat ambiguous, but it seems very likely that this galaxy is a dwarf member of the Local Group.
