Abstract
Systems and methods are provided for modifying video content to improve lighting of a person's face depicted within the video content. Pixels depicting skin may be detected in a first frame of the video content. Transformation parameters may then be determined based on intensity values of the pixels depicting skin, where the transformation parameters represent adjusted pixel intensity values determined to improve at least one of brightness or contrast of the pixels depicting skin. Based on the transformation parameters, intensity association data may be generated and stored that associates each possible input pixel intensity value in at least one channel with a corresponding adjusted pixel intensity value. The stored intensity association data as determined with respect to the first frame may then be reused to modify intensity values for a series of frames of the video content.
