Abstract:
In one implementation, a method includes obtaining an image. The method includes splitting the image to produce a high-frequency component image and a low-frequency component image. The method includes downsampling the low-frequency component image to generate a downsampled low-frequency component image. The method includes correcting color aberration of the downs ampled low-frequency component image to generate a color-corrected downsampled low-frequency component image. The method includes upsampling the color-corrected downsampled low-frequency component image to generate a color-corrected low-frequency component image. The method includes combining the color-corrected low-frequency component image and the high-frequency component image to generate a color-corrected version of the image.
