  • Adaptive sharpening for blocks of upsampled pixels
    Patent number: 12755352
    Abstract: Methods and processing modules apply adaptive sharpening, for a block of input pixels for which upsampling is performed, to determine a block of output pixels. A block of upsampled pixels is obtained based on the block of input pixels. One or more range kernels is determined based on a plurality of upsampled pixels of the block of upsampled pixels. Each of the one or more range kernels is combined with a sharpening kernel to determine one or more bilateral sharpening kernels. The one or more bilateral sharpening kernels are used to determine the output pixels of the block of output pixels.
