基于DPS-ARM图像增强技术
本文在分析总结现有图像增强技术的基础上，用DSP实现了中值滤波的实时图像增强，并采用拉普拉斯（Laplacian）算法对图像进行了增强，同时利用DSP建立了该方法的实时实现系统，分析了基于小波的图像增强方法，具有很好的抗噪性能。图像增强效果明显优于传统图像增强方法，但是，小波变换后的结果为浮点数，由于计算机有限字长的影响，往往不能实现精确地重构信号，并且不容易硬件实现。为了解决小波变换存在的问题，采用了提升小波变换方法，利用图像局部信息，克服了对每个像素采用相同尺度变换处理带来的缺点，最终得到了良好图像增强效果。在算法仿真的基础上，本文建立了DSP/ARM嵌入式仿真开发平台，利用DSP芯片固有的高速运算性能和ARM芯片的强有力控制和通讯能力，满足了图像增强实时动态仿真要求。完成了图像增强的实时处理过程，同时也为其他实时动态仿真构成了一个嵌入式系统仿真平台。

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.
