  • Entropy-dependent adaptive image filtering
    Patent number: 11908085
    Abstract: Systems and methods include determination of an entropy value associated with each of a plurality of voxels of a three-dimensional image, determination, for each of the plurality of voxels, of a respective filter based on the entropy value associated with the voxel, wherein a first filter determined for a first voxel associated with a first entropy value is different from a second filter determined for a second voxel associated with a second entropy value different from the first entropy value, application, for each of the plurality of voxels, of the respective filter to a value of the voxel to generate a replacement value for the voxel, and generation of a filtered three-dimensional image based on the generated replacement value of each of the plurality of voxels.
