| Summary: | In view of the problem that energy consumption of sensor nodes is fast and equipment life is cut caused by large amount of information transmission of wireless sensor network, a kind of compressed sensing image processing algorithm based on wavelet transform was put forward. The algorithm uses sym8 wavelet for image sparse and fragmental processing, and uses measurement matrix for adaptive sampling measurement, and finally reconstructs image through OMP algorithm and wavelet inverse transformation. The experimental results show that the proposed algorithm can obtain reconstructed image with high quality by lower sampling rate compared with traditional compressed sensing algorithm.
