Patent ID: 11869169
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 4:
5. The electronic device of claim 1, wherein the processor is further configured to:
generate a prototype kernel for each possible combination of a pixel color and a coherence, a strength, and an orientation of an image edge;
divide the prototype kernel into a plurality of polyphase kernels;
for each polyphase kernel having a fractional weight phase, determine a regularized polyphase kernel having a regularized primary axis and a regularized secondary axis;
normalize coefficients of the regularized polyphase kernels to generate a dictionary of adaptive kernels; and
select 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.
