Multiscale recurrent pattern image coding with a flexible partition scheme
In this paper we present a new segmentation method for the Multidimensional Multiscale Parser (MMP) algorithm. In previous works we have shown that, for text and compound images, ...

Local Binary Patterns as an Image Preprocessing for Face Authentication
One of the major problem in face authentication systems is to deal with variations in illumination. In a realistic scenario, it is very likely that the lighting conditions of the ...

Exploitation of 3D Images for Face Authentication Under Pose and Illumination Variations
An appearance-based face authentication system integrating 2D color or intensity images and 3D data is presented in this paper. The proposed system is based on a low-cost 3D and c...

JPEG2000-based secure image authentication
We present an efficient JPEG2000-based image authentication scheme, which is robust to JPEG compression and other allowed signal processing operations. Positive wavelet-based wate...
