Abstract
In one aspect, a method, includes producing a centralness metric that is highest at a center of detail from a set of pixels and having a negative slope to neighboring pixels from a center pixel at the center of detail, calculating a delta signal for the set of pixels using the produced centralness metric and pixel values of the set of pixels, generating a squeezed pixel value for each of the pixel values of the set of pixels, and outputting the generated squeezed pixel values.
Claims22
A method, comprising:
- producing a centralness metric that is highest at a center of detail from a set of pixels and having a negative slope to neighboring pixels from a center pixel at the center of detail;
- calculating a delta signal for the set of pixels using the produced centralness metric and pixel values of the set of pixels;
- generating a squeezed pixel value for each of the pixel values of the set of pixels;
