Abstract

The embodiments of the invention disclose a method and an apparatus for extracting moving objects. The method comprises: using an analyzing algorithm to determine the matrix model corresponding to an image; in the process of iterative processing for the matrix model, updating the constraint multiplier two times in each iteration attempt; and based on the iteration result, extracting the moving objects in the image. In the invention, since the constraint multiplier is updated two times in each iteration attempt, the updating speed of the constraint multiplier is increased; the faster the updating speed is, the faster the convergence speed for the iterative algorithm is achieved. With the technical schemes of the invention, the iterative processing becomes quicker and takes a shorter time.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for extracting a moving target. Background technique [0002] In the process of image processing, it is often necessary to extract moving objects in the image. Existing moving target extraction schemes usually include: [0003] 1. Use RPCA (robust principal component analysis, based on robust principal component analysis) algorithm to determine the matrix model corresponding to the image. The matrix model includes a foreground matrix and a background matrix. The foreground matrix is ​​the matrix corresponding to the moving target; [0004] 2. For the determined matrix model, use ADM (Alternating Direction Methods, Alternating Direction Method) to iteratively solve; [0005] 3. After the iterative process is over, the foreground matrix in the matrix model is determined, and then the moving target in the image is extracted. [0006] In the above solution, the ...
