Method for scaling channel of an image

摘要

The present invention relates to a method for scaling a first channel, wherein the method comprises computing a low resolution second channel based on a transformation of the second channel with a transformation function used to transform high resolution channel into a low resolution channel; computing a correlation function between the low resolution second channel and the first channel; determining a predicted second channel having the high resolution from the low resolution second channel according to a prediction method; computing an high-pass second channel based on the difference between the second channel and the predicted second channel and based on the correlation function; determining a predicted first channel having the high resolution from the first channel according to the prediction method.

1. A method for enhancing an image, comprising:
determining a first channel of low resolution and a second channel of high resolution based on a frame of the image; applying a transformation function to the second channel to compute a low-resolution second channel; determining a correlation between the low-resolution second channel and the first channel; computing a high-pass second channel based at least in part on the second channel and the correlation; and enhancing the image via scaling the first channel based at least in part on the high-pass second channel.
