Google patents video filter that uses color data to sharpen images

Google has filed a patent for a method to improve the quality of decoded video frames. The technique applies a specific filter to one color channel of an image using pixel values from a different color channel to enhance the final picture.

Why it mattersThis is a standard improvement in video compression technology that could lead to slightly clearer video streams with the same data size, though it is unlikely to be noticeable to most viewers.

In the filing’s own words

A reconstructed frame is generated by decoding an encoded frame from a compressed bitstream. The reconstructed frame includes a first color plane and a second color plane. An enhanced reconstructed frame is obtained by applying a filter to at least one pixel of the first color plane of the reconstructed frame using at least one pixel value of the second color plane.

What exactly they claim (claim 1)

1. A method, comprising: generating a reconstructed frame by decoding an encoded frame from a compressed bitstream, wherein the reconstructed frame comprises a first color plane and a second color plane; and obtaining an enhanced reconstructed frame by applying a filter to at least one pixel of the first color plane of the reconstructed frame using at least one pixel value of the second color plane.
