A Deep Learning-Based Method for Enhancing the Signal-to-Noise Ratio of Star Sensor Images
Remote SensingIn window tracking mode, stray light and detector readout noise can submerge star spot signals in star sensor images. The resulting degradation reduces centroid extraction accuracy and may even cause extraction failure, thereby preventing precise ...

Improving Peak Signal-to-Noise Ratio through Wavelet-Based Noise Reduction
Image denoising is one of the basic tasks in image processing, since images may undergo distortions during acquisition, processing, compression, transmission, or reconstruction (Shukla and Patel, no date). Moreover, because both noise and image edges are characterized by high frequencies, conventional denoising often results in unavoidable loss of edge
