Method of predicting perceptual differences between memory and directly viewed colors in video

摘要

Disclosed is a processor for predicting perceptual differences between colors recalled from memory and directly viewed colors in a tested video. The processor includes a memory effects processor structured to generate compensation factors for distortions of color due to memory effects and apply the compensation factors to data from the reference video or data from the tested video. The compensation factors may include factors for changes in saturation over time, changes in hue angle, changes in uncertainty, and a categorization factor that reflects a trend in shifts and towards cardinal color centroids over time in memory.

主权项

1. A processor for predicting perceptual differences between colors recalled from memory and directly viewed colors in a tested video, comprising:
an input for accepting a reference video and the tested video; a memory effects processor structured to generate a compensation factor for distortions of color due to memory effects and apply the compensation factor to data from the reference video or data from the tested video, in which the compensation factor comprises a factor to account for a change toward a cardinal color in memory over time; an output structured to deliver a set of perceptual difference measurements; a perceptual response generator structured to generate a perceptual response for the reference video and the tested video; and a categorization processor structured to apply a categorization process to the perceptual response for the reference video and to the perceptual response for the tested video, and in which the compensation factor is applied to the categorized responses.
