We present in this report an approach to automatic detection of human faces in color images. The proposed approach consists of three parts: a human skin segmentation to identify probable regions corresponding to human faces; adaptive shape analysis to separate isolated human faces from initial segmentation results; and a view-based face detection to further identify the location of each human f...

Semantic segmentation has been widely investigated for its important role in computer vision. However, some challenges still exist. The first challenge is how to perceive semantic regions with various attributes, which can result in unbalanced distribution of training samples. Another challenge is accurate semantic boundary determination. In this paper, a contour-aware network for semantic segm...

computer-aided diagnosis (cad) systems can assist radiologists in several diagnostic tasks.  lung segmentation is one of the mandatory steps for initial detection of lung cancer in posterior-anterior chest radiographs. on the other hand, many cad schemes in projection chest radiography may benefit from the suppression of the bony structures that overlay the lung fields, e.g. ribs. the original ...
