Lattice Boltzmann model-based video image defect repairing method

The invention discloses a lattice Boltzmann model-based video image defect repairing method. The method comprises operation steps: 1) a to-be-repaired object is inputted; 2) a format of the repaired object is judged, and if the repaired object is an image, a fifth step is carried out for repairing, or otherwise, a third step is carried out; 3) a format of inputted video signals is judged, a digital video is firstly converted via a video acquisition card in the case of an analog video, and a fourth step is then carried out, or otherwise, the fourth step is directly carried out; 4) the video is decomposed into frames; 5) the mentioned lattice Boltzmann method is used for repairing each decomposed frame image; and 6) the needed output format is judged, a video is synthesized in the case of need, or otherwise, the image is directly outputted. According to the lattice Boltzmann repairing method, particle density of each node in the model is updated during a collision and transfer process, and output is carried out if iterations are reached or a threshold condition is met. The repairing method is simple in realization and good in parallelism, and the repairing efficiency can be improved while the repairing quality is good.
