Among them, the most important of the pattern recognition algorithm and the matching pursuit algorithm is the classification algorithm. Generally, there are K-NN classification method, Bayesian classification method, PCA classification method, etc. The disadvantage is that the calculation amount is huge, and a 32*32 image is not optimized. The time operation dimension is also 1024, the amount of operation reaches one million, and the time complexity is n to the 4th power, where n is the image side length. Secondly, for objects that are constantly changing in motion, a single pattern recognition can no longer meet the recognition accuracy requirements, and the use of matching tracking will increase the amount of computation. It is difficult to achieve real-time recognition on current mobile phone hardware. sexual demands
