In this paper, we propose a new local tone mapping (TM) algorithm, which combines luminance compression function with an adaptive color saturation control parameter. The luminance of the radiance map is decomposed by a bilateral filter and compressed by the modified luminance compression function. To generate color channels of the tone mapped image, we use color ratios and color saturation control...
Tone mapping (TM) algorithms reproduce the high dynamic range (HDR) images on low dynamic range (LDR) display devices such as monitors or printers. In this paper, we propose a local TM algorithm, in which the HDR input is segmented using the K-means algorithm and a display gamma parameter is set automatically for each segmented region. The proposed TM algorithm computes the luminance of an input that...

This paper proposes an adaptive edge-preserving smoothing and detail enhancement for video preprocessing of H.263. The proposed method consists of two steps: edge preserving smoothing using a motion-adaptive bilateral filter and detail enhancement using an adaptive high-boost filter. In the first step, the motion-adaptive bilateral filter preserves edges in region of interest (ROI) and smoothes noise...
