摘要

多年来，图像编辑和后期处理技术已经成熟，这使得很难(几乎不可能)评估图像是否被数字增强或以某种方式篡改。然而，复杂的操作仍然依赖于熟练的用户输入，煞费苦心地绘制像素。我们介绍了我们最近和正在进行的高级图像编辑技术的工作，通过利用人类视觉系统的局限性和高动态范围图像中可用的丰富信息来扩展当前的工具。心理物理学在感知空间中工作，在评估结果的有效性方面起着重要作用。

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.
