Adaptive detail enhancement of images systems and methods

Abstract

Techniques are provided to adaptively enhance details of images. In one example, a method includes receiving a base image including a plurality of base pixels arranged in rows and columns. The method further includes performing a column-wise filtering process including processing subsets of the base pixels of each column selected by first and second sliding windows to generate a plurality of column-processed pixels. The method further includes performing a row-wise filtering process including processing subsets of the base pixels of each row selected by third and fourth sliding windows to generate a plurality of row-processed pixels. The method further includes combining the column-processed pixels and the row-processed pixels to generate a smoothed image that exhibits reduced detail in relation to the base image, and subtracting the smoothed image from the base image to provide a detail image. Additional methods and systems are also provided.
