D-B-S separation and tone reproduction using DCT band splitting for LDR image transmission
Geun‐Young Lee, Sung-Hak Lee, Kyu‐Ik Sohng · 2013
In pursuance of the tone mapping for LDR images, the proposed method inserts the tone mapping into JPEG baseline not as post-processing. First, an image is decomposed in detail, base, surround images in term of DCT coefficients. Then, a surround-adaptive tone mapping is applied to the base image. In addition, a compensation module is added for the defects such as desaturation and sharpness falling resulted by tone mapping. As a result, it is confirmed that transmitted JPEG images are enhanced in term of image quality.
