Claim One:
1. An apparatus for performing object detection and extraction from image sequences, comprising: (a) a computer processor; and (b) programming in a non-transitory computer readable medium and executable on said computer processor for performing steps comprising: (i) downsizing images from an image sequence; (ii) buffering at least three sequential images of the image sequence in a circular buffer; (iii) aligning a previous image and a next image to a current image of said image sequence and outputting a previous difference between the previous image and the current image, and a next difference between the current image and the next image; (iv) determining absolute differences between an aligned previous image and an aligned current image, and between the aligned current image and an aligned next image; (v) removing non-overlaps which are redundant non-corresponding sections due to the non-overlap; (vi) detecting contours on each difference image; (vii) performing an intersection between the previous difference and the next difference to retain contours of the current image only; (viii) performing gradient tracing to recover any missing object contour information; (ix) generating an object mask and assigning color attributes to a bounding box; and (x) eliminating outliers and clearing the object mask of untracked objects to output a binary mask configured for moving objects and rectangular bounding box information; whereby said apparatus automatically extracts dynamic moving objects from a sequence of images captured from cameras which do not require static platforms.
