All Colors Motion Estimation for the Frame Sequential Video with Pastel Color

摘要

Currently, Y, Cb, Cr 4:2:0 system is widely used as the color format for the video system. We have proposed the frame sequential system as an alternative method which has one color plane in a frame. In this system, the conversion to usual RGB requires a motion compensated color interpolation. However, it is not easy in the case of high saturation color images, because of its difference between color planes. To solve this problem, we have proposed the color format which has dependent colors. The primary colors (RGB) are changed to pastel colors. To address the conversion to RGB, motion estimation should be used, some problem of motion vector still remains. To correct motion vectors, the process of motion estimation should be enhanced. In this paper, all colors motion estimation is added as new motion estimation after the previous motion estimation. We use these processes as two stages motion estimation. Two stages motion estimation is compare to the previous only. From experimental results, all colors motion estimation gives higher PSNR. The maximum of PSNR gain is about 1dB.
