Bit-length (i.e., resolution of signal amplitude) of digital images is decided by the quantization. The bit-length expansion technique is necessity for the high-quality display such as the liquid crystal display (LCD) and the plasma display. Since, these displays have more the 10 bit resolution for each color component. However, in general, color image signals are defined by 8 bit resolution for each...
In the case of digital image/video processing, color images are represented in the YCbCr. The Y component is the luminance of the color. The other two components Cb,Cr represent the color-difference component. The bandwidth of Cb,Cr components are much smaller than that of luminance signal. Thus, this color space is suitable for image compression and adopted for JPEG and MPEG. The YCbCr color space...
The restoration of video signals corrupted by the additive noise is important for getting the high quality video and the high compression ratio of video signals. In this paper, we propose a novel restoration method for video signals corrupted by the Gaussian noise. Conventional methods use the spatio-temporal filtering after the motion compensation. However, the accuracy of the motion compensation...
