HVS-aware ROI-based illumination and color restoration

We present the framework for Human visual system (HVS)-aware Region of interest (ROI)-based Illumination and Color Restoration called `HRICR´ for restoring distorted images taken under the arbitrary illumination environment. The proposed method is effective for appropriate illumination and vivid color restoration as well as suppression of artifacts such as HALO and noise amplification. We introduce the ROI-based parameter estimation dealing with small shadow area against spacious well-exposed background in an image for the touch-screen camera. The perceptual difference threshold is obtained using just-noticeable-difference (JND) based on HVS in response to user interaction.
