Based on the DPS - ARM image enhancement techniques
Based on the analysis of the technology of image enhancement, based on DSP is realized by the real-time median filtering, and using Laplacian image enhancement algorithm for image Laplacian (the), using the method of DSP built real-time system are analyzed, based on wavelet image enhancement method, has the good function of noise. Image enhancement is obviously superior to traditional image enhancement method, however, the wavelet transform, the results for the floating-point word long effect due to limited, computer often cannot achieve accurately reconstruct signal, and not easy to hardware implementation. In order to solve the problems of wavelet transform, the wavelet transform method, the promotion of image information for each pixel, overcome with the same scale transform faults, eventually brought to get a good image enhancement effect. In the algorithm based on the simulation, this paper established a DSP/ARM embedded simulation platform, using DSP chip high-speed operation of the inherent properties and the strong ARM chip control and communication ability, and meet the requirement of real-time dynamic simulation image enhancement. Finish the image enhancement of real-time process, as well as other real-time dynamic simulation constitutes an embedded system simulation platform.
