1. A method comprising:
obtaining an image, wherein each pixel of the image is associated with a luma value, a blue-chroma value, and a red-chroma value; and
correcting color aberration of the image comprising, for a particular pixel of the image:
determining one or more chromatic characteristic values for the particular pixel based on one or more blue-chroma values or one or more red-chroma values of one or more pixels within a neighborhood of the particular pixel;
determining a likelihood that the particular pixel exhibits color aberration based on the one or more chromatic characteristic values for the particular pixel;
generating a filtered version of the particular pixel by filtering the particular pixel using the one or more pixels in the neighborhood surrounding the particular pixel; and
generating a color-corrected version of the particular pixel based on the likelihood that the particular pixel exhibits color aberration and the filtered version of the particular pixel.
