Abstract:
1. A method for detecting motion in a high resolution video, comprising: dividing an image frame of a high resolution video into a number of blocks; determining whether motion is present in each of the blocks; identifying, within each block in which motion is determined to be present, pixels in which motion is present by applying a pixel based motion detection algorithm to each pixel of each block in which motion is determined to be present, wherein the pixel based motion detection algorithm is a kernel density estimation based motion detection algorithm; dividing a subsequent image frame of the high resolution video into a number of blocks corresponding to the number of blocks into which the image frame is divided; determining whether motion is present in the blocks of the subsequent image frame that correspond to the blocks of the image frame in which motion is determined to be present and blocks of the image frame adjacent to the blocks in which motion is determined to be present; and identifying, within each block of the subsequent image frame in which motion is determined to be present, pixels in which motion is present.
