Abstract: With the advance of modern technology, we are looking for image/video representations with more realism. The popularity of HDTV (high definition TV) reveals that high resolution and high quality video soon becomes the milestone of the next video standard. Consequently, bit-depth scalability is likely becoming one important feature for the coming video coding standard. In this paper, we propose new tone mapping and tone reproduction techniques based on human visual perception. Then the proposed techniques will be applied on the bit-depth scalable video coding scheme. Experimental results show that the proposed coding scheme outperforms the prior work and the visual quality of low bit-depth images is promising.
