Perception-based image editing

Image editing and post-processing techniques have matured over the years, making it difficult (verging on impossible) to assess whether an image has been digitally enhanced or doctored somehow. However, complex manipulations still rely on skilled user input, painstakingly painting over pixels. We present our recent and on-going work on advanced image editing techniques, extending current tools by leveraging the limitations of the human visual system and the wealth of information available in a high dynamic range image. Working in perceptual space, psychophysics plays an important role in assessing the validity of the results.
