Fine moving object in Field Extraction

The present invention relates to the field of fine moving target extraction method, comprising: obtaining a sequence of images that contain moving objects, and the sequence of image pre-processing; the pretreated sequence diagram frame difference after doing is divided into a plurality of grids, according to the gate eigenvalues ​​determination target cell where the movement area, and use the grid method to extract target motion area further refine the target range; in the movement area of ​​the target to background modeling, obtained by background subtraction target binary diagram, and the binarized pixel-level process diagram with feedback; binarization processed FIG mapped to the target area where the color image, and dividing the super-pixel color image area; and the segmentation results FIG binary fusion, based on the fusion results, calculated for each pixel super-confidence, and ultimately get the refinement of the moving object after thresholding. The present invention may be implemented in a complex background than the real-time, robust extraction, fine field moving target.
