Abstract: We extracted micro-movement target of real-time video images under the multi-thread conditions. Based on the multi thread ideas, we used skin colour detection and clustering methods to process and solve the access violation condition. hhe ideology of edge detection was used locate the range of the moving object, and then clustering algorithm and skin color detection and some other methods were used extract the object template and complement the integrity of the object template, and according to the object template and corresponding pixel coordinates of the original image, the original pixel color onto the corresponding position of new background model. The simulation results show that the proposed method ensure the quality requirements of real-time processing and has a certain robustness, so this method satisfies the needs of the project.

Key words: Multi-thread, Micro-movement target, Clustering algorithm, Skin colour detection, Object template
