Optimizing the disparity map by the integration of HVS binocular properties for efficient coding of stereoscopic images

Stereoscopic imaging technologies are seen as the next generation of visual presentation, improving the quality of experience of the viewer. It uses two different sequences acquired from two regular cameras or from a regular camera with an additional specific depth camera. This means that the size of data is at least doubled. Thus, the coding process becomes very crucial. In this framework, we propose a stereoscopic coder based on visual properties. The matching of two images is computed by a binocular energy model based on the simple and complex cells functions allowing the fusion of both retinal images in the visual cortex. Mathematical functions were used to reproduce the behavior of these cells particularly complex wavelet transform (CWT) and bandelet transform. Our coder output is a disparity map, a residual image and the reference image. The innovative part of this work lies in a matching technique based on the binocular energy. The results are presented through comparative curves with one of the most known coder in literature.
