Title: METHOD OF DECAYING CHROMINANCE IN IMAGES
Abstract:
A method and system for decaying chrominance. One or more processors obtain a selected one of a series of root images of a digital video. The selected root image includes root pixels each associated with color values. The processor(s) selects one of the root pixels until each of the root pixels has been selected. The color values associated with the selected root pixel are expressible as a color vector with a plurality of elements each storing a different one of the color values. The processor(s) determines a perceptual luminance value for the selected root pixel, generates a monochromic vector for the selected root pixel, generates a biased monochromic vector by multiplying the monochromic vector with a bias, and generates new color values associated with a new pixel of a denoised image corresponding to the selected root pixel by blending the biased monochromic vector with the color vector.
