Hvs Based High Dynamic Range Video Compression with Optimal Bit-depth Transformation
نویسندگان
چکیده
High Dynamic Range (HDR) technology is able to offer high levels of immersivity with a dynamic range comparable to the Human Visual System (HVS). A primary drawback of HDR is that its memory and bandwidth requirements are significantly higher than for conventional video. The challenge is thus to develop means for efficiently compressing the video to a manageable bit rate without compromising perceptual quality. In this paper, we propose an HDR compression method based on an optimized bit-depth transformation, and wavelet-based HVS modelling. Experimental results indicate that the proposed method outperforms previous approaches and operates in accordance with characteristic of the HVS, tested objectively using Visible Difference Predictor (VDP).

With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...
