Journal ArticleDOI
Color Demosaicing Using Variance of Color Differences
King-Hong Chung,Yuk-Hee Chan +1 more
TL;DR: An adaptive demosaicing algorithm that can effectively preserve the details in texture regions and, at the same time, it can significantly reduce the color artifacts is presented.
Journal ArticleDOI
On the realization of discrete cosine transform using the distributed arithmetic
Yuk-Hee Chan,Wan-Chi Siu +1 more
TL;DR: An efficient unified DCT/IDCT chip is proposed to demonstrate the superiority of the formulation and can easily meet the speed requirement of 14.3 MHz real-time operation with the current 2 mu m CMOS technology.
Journal ArticleDOI
A Lossless Compression Scheme for Bayer Color Filter Array Images
King-Hong Chung,Yuk-Hee Chan +1 more
TL;DR: Simulation results show that the proposed prediction-based lossless compression scheme can achieve a better compression performance than conventional lossless CFA image coding schemes.
Journal ArticleDOI
Reduction of block-transform image coding artifacts by using local statistics of transform coefficients
TL;DR: The proposed method can significantly reduce coding artifacts of low bit-rate coded images, and at the same time guarantee that the resulting images satisfies the quantization error constraint.
Journal ArticleDOI
Feature-preserving multiscale error diffusion for digital halftoning
Yuk-Hee Chan,Sin-Ming Cheung +1 more
TL;DR: The proposed method can eliminate the pattern noise in flat regions and the boundary effect found in some other conventional multiscale error diffusion methods and preserve the local features of the input image in the output.
