Abstract
The present disclosure covers systems and methods of efficiently filtering digital images. More particularly, the present disclosure covers systems and methods that generate and maintain a list of unique pixel values within a kernel window. Using the list, the systems and methods determine filtered pixel values for a filtered output image by processing only the counts of pixels in the histogram associated with the unique pixel values of the list. By considering selective pixel values of the histogram based on the unique pixel values of the list, the systems and methods reduce computations as part of the filtering process.
