1. 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; and
displaying the set of pixels on a display based on the generated squeezed pixel values.
