Abstract
System and methods are provided for performing image noise reduction. A pixel having an initial pixel value is selected from an image for performing noise reduction, wherein the image is stored in a data structure in a non-transitory computer-readable storage medium. A block window including a plurality of pixel blocks associated with the selected pixel is determined, wherein a pixel block includes a plurality of pixels. A plurality of pixel block average values for the plurality of pixel blocks are calculated, wherein a pixel block average value corresponds to an average pixel value of a pixel block. A weighted average of the plurality of pixel block average values with respect to the selected pixel is calculated using a bilateral filtering algorithm. The data structure is updated by replacing the initial pixel value of the selected pixel with the weighted average of the plurality of pixel block average values.
