Abstract:
1. A method, comprising: accessing, by a processor, an image; partitioning, by the processor, the image into a group of blocks including first blocks, first surrounding blocks that are each adjacent to one of the first blocks, second blocks, and second surrounding blocks that are each adjacent to one of the second blocks; calculating, by the processor, principle bilateral filtered image components for the first blocks responsive to determinations that a first pixel within each of the first blocks has a first intensity level within a pre-determined intensity range or responsive to a determination that a second pixel within the first surrounding blocks has a second intensity level within the pre-determined intensity range, wherein the principle bilateral filtered image components are not calculated for the second blocks responsive to a determination that pixels within the second blocks have intensity levels outside of the pre-determined intensity range and responsive to a determination that pixels within the second surrounding blocks have intensity levels outside of the pre-determined intensity range; and applying, by the processor, an infinite impulse response filter to the image using the principle bilateral filtered image components.
