In this paper, we proposed tone mapping method which uses threshold function. It was impossible for conventional Multi-Scale Retinex algorithm to express detail parts due to damage in bright region of dynamic range at compression processing. We reduce the damage, which occurs in tone mapping process, by setting the threshold of Log Scale image in this algorithm. The experimental tests demonstrated...
H.264/AVC is adopted to a variety of applications because of its high compression efficiency. The high coding efficiency of H.264 is mainly acquired from the newly allowed prediction schemes including variable block mode. However these schemes require a high complexity to select the optimal mode. In this paper, to reduce this large computational burden, an adaptive fast inter mode decision algorithm...
To display high dynamic range (HDR) images onto conventional displayable devices that have low dynamic range (LDR) such as monitors and printers, we propose a piecewise tone reproduction operator with chromatic adaptation. The strong point of our operator is to reproduce displayable LDR images while maintaining a perceptual match between the real world and the displayed image. The algorithm for dynamic...
This paper describes a high definition display adaptive resampling algorithm which based on the direction oriented interpolation algorithm. In the large display market, FPD has become common than CRT in these days. Although the FPD has high panel resolution, the interlaced signal cannot be displayed on FPD. Thus, FPD requires more adaptive image signal processing for display high resolution and progressive...
