Abstract:
1. A method comprising: determining, by a computing device, a structure descriptor for an m×n pixel block of an image, wherein the m×n pixel block contains a primary pixel having a primary pixel value and a plurality of secondary pixels having respective secondary pixel values, wherein the structure descriptor includes a plurality of structure indicators each associated with a respective secondary pixel, and wherein the respective structure indicators are based on the primary pixel value and the respective secondary pixel value of the associated secondary pixel; based on the structure descriptor, determining a structure value for the m×n pixel block; based on the structure value, applying image processing to the m×n pixel block to form a second m×n pixel block of the image; determining a second structure descriptor for the second m×n pixel block; based on the second structure descriptor, determining a second structure value for the second m×n pixel block; and based on the structure value and the second structure value, merging the m×n pixel block and the second m×n pixel block, wherein merging the m×n pixel block and the second m×n pixel block comprises determining an absolute difference between the first structure value and the second structure value, determining that the absolute difference is greater than a threshold difference, and based on the absolute difference being greater than the threshold difference, assigning the m×n pixel block more weight than the second m×n pixel block during the merging.
