This paper addresses an application that has not been much explored, the de-identification of faces with expressions preservation in images. With the huge amount of images and videos shared on the Internet, protecting the identity of people in the data becomes crucial. Removing the identity information is often referred as de-identification. In this paper, we propose a novel de-identification process...
We propose a transcription on graphs of recent continuous global active contours proposed for image segmentation to address the problem of binary partitioning of data represented by graphs. To do so, using the framework of Partial difference Equations (PdEs), we propose a family of nonlocal regularization functionals that verify the co-area formula on graphs. The gradients of a sub-graph are introduced...
In this paper, we present a graph-based multi-resolution approach for mitosis extraction in breast cancer histological whole slide images. The proposed segmentation uses a multi-resolution approach which reproduces the slide examination done by a pathologist. Each resolution level is analyzed with a focus of attention resulting from a coarser resolution level analysis. At each resolution level, a...
