Evaluation of U-Net Backbones for Cloud Segmentation in Satellite Images
2023
Laura Arakaki 1 Melo 2 ; André Backes 3 ; Mauricio Escarpinati
https://www.scitepress.org/PublicationsDetail.aspx?ID=NTx/%2BnRebnA%3D&t=1 Remote sensing images are an important resource for obtaining information for different types of applications. The occlusion of regions of interest by clouds is a common problem in this type of image. Thus, the objective of this work is to evaluate methods based on convolutional neural networks (CNNs) for cloud segmentation in satellite images.

Identifying Malignant Skin Diseases Through Deep Learning
2025
Matheus Vieira da Silva, João Fernando Mari, Gabriel Sávio de Lima Mota
https://seer.ufrgs.br/index.php/rita/article/view/143463 Early and accurate identification of malignant skin diseases is critical to improving treatment outcomes and patient prognosis. Current diagnostic methods heavily rely on visual assessments by medical professionals, followed by biopsies for confirmation. These approaches can be subjective and require significant expertise, while access to specialized care remains limited, particularly in developing regions.
