The algorithm is based on a disparity map computation and an anaglyph synthesis. The disparity map was first estimated by employing the wavelet atomic functions technique at several decomposition levels in processing a 2D video sequence. Then we used an anaglyph synthesis to apply the disparity map in a 3D video sequence reconstruction. Compared with the other disparity map computation techniques such as optical flow stereo matching wavelets etc. the proposed approach produces a better performance according to the commonly used metrics structural similarity and quantity of bad pixels . The hardware implementation for the proposed algorithm and the other techniques are also presented to justify the possibility of real-time visualization for 3D color video sequences.

Introduction Conversion of available 2D content for release in threedimensional 3D is a hot topic for content providers and for success of 3D video in general. It naturally completely relies on virtual view synthesis of a second view given the original 2D video 1 . 3DTV channels mobile phones laptops personal digital assistants and similar devices represent hardware in which the 3D video content can be applied. There are several techniques to visualize 3D objects such as using polarized lens active vision and anaglyph. However some of those techniques have certain drawbacks mainly the special hardware requirements such as the special display used with the .
