A temporal filter may perform dynamic motion estimation and compensation for filtering an image frame. A row of pixels in an image frame received for processing at the temporal filter may be received. A motion estimate may be dynamically determined that registers a previously filtered reference image frame with respect to the row of pixels in the image frame. The reference image frame may be aligned according to the determined motion estimate, and pixels in the row of the image frame may be blended with corresponding pixels in the aligned reference image frame to generate a filtered version of the image frame. Motion statistics may be collected for subsequent processing based on the motion estimation and alignment for the row of pixels in the image frame.
