CL4 wavelet real-time processing and FPGA realization based on image blocking

LI Xiao-ming;LIU Hai-yan;Army Officer Academy;Anhui Key Laboratory of Polarized Light Imaging Detection Technology,Army Officer Academy;Detachment 52,Unit 73101 of PLA;  
CL4 wavelet has some excellent characters and is widely applied to infrared image processing of small weak targets,but its worse real-time performance limits its application. The quantification method of wavelet coefficient is researched on the basis of structure analysis of CL4 wavelet algorithm. A method which blocked the original image into some sections is proposed according to CL4 algorithm,which is realized by the pipeline algorithm used in FPGA. The key algorithm was simulated with Model Sim. The method improved real-time performance of CL4 algorithm.
