Abstract
A low-latency method for applying image processing steps includes processing and displaying portions of the image as they are received in real-time. In a denoising process, the portion is denoised by selecting pixels, establishing a block centered on each pixel, identifying similar blocks within the portion, and performing a filtering process such as hard thresholding before the entire image is received. Pixels within each block may also be averaged.
