Classification: CPC G | IPC G

Claim 17:
18. The method of claim 15, further comprising:
generating a prototype kernel for each possible combination of a pixel color and a coherence, a strength, and an orientation of an image edge;
dividing the prototype kernel into a plurality of polyphase kernels;
for each polyphase kernel having a fractional weight phase, determining a regularized polyphase kernel having a regularized primary axis and a regularized secondary axis;
normalizing coefficients of the regularized polyphase kernels to generate a dictionary of adaptive kernels; and
selecting the kernels for red, green, and blue pixels from the dictionary of adaptive kernels based on a coherence, a strength, and an orientation of the input Bayer frame at the output RGB pixel.
