This paper discusses a new Tone Mapping (TM) approach converting a High Dynamic Range (HDR) image into a Low Dynamic Range (LDR) image able at the same time to extract the relevant details and enhance the contrast of LDR images to ensure a good LDR image visual quality. This approach uses an advantage of multiresolution and piecewise linear perceptual quantization. While multiresolution part at each resolution level extracts much more detail information from HDR image to become a LDR coarse
more » ... e, perceptual quantizer part adjusts the LDR coarse by the pixel's distribution using a piecewise linear function so that the final LDR image can be visualized near human visual system. Simulation results provide good results, both in terms of visual quality and TMQI metric, compared to existing competitive TM approaches.
