SAR Images Despeckling Using Convolutional Neural Networks with Stochastic Distances

This work presents a study on speckle noise filtering in SAR images using convolutional neural networks. The objective is to develop an accessible and efficient solution to improve the quality of images degraded by this type of noise, facilitating their analysis and interpretation. The proposed methodology involves the using synthetic SAR-like data, the training of a convolutional neural network, and the evaluation of results using traditional metrics such as PSNR and SSIM. Additionally, stochastic distances were integrated into the loss function of the convolutional neural network, enabling a more detailed analysis of the preservation of the statistical properties of the filtered images. The results indicate that the model effectively reduces speckle noise while preserving the structural details of the image. Furthermore, comparisons with recent studies on the topic showed that the proposed solution achieves competitive performance.
