Abstract: The present invention is directed, in at least one embodiment, to a method of estimating noise and, subsequently, filtering noise in a single frame of video data. The method comprises the steps of obtaining a single frame of video data within a memory and executing a plurality of instructions within a processor wherein, when executed, the instructions identify a window within the single frame, compute a variance of the window, derive a noise estimation from the variance, and filter the noise from the single frame using the noise estimation. The method is effective to remove Gaussian noise and blocky noise.

Abstract: The present invention is directed to systems and methods for deinterlacing a video frame by obtaining a video frame, identifying an edge within the frame, selecting a first pixel within the edge, computing a plurality of non-negative threshold values by applying at least one function to a plurality of pixels proximate to the first pixel, obtaining a plurality of second pixel values based upon the computation of non-negative threshold values, and applying a filter function to the selected plurality of second pixel values.
