The Application of Parallel Algorithm for 2-D in Image Processing Based on Wavelet Transform

为实现多功能摄影监视器的高分辨率与图像快速传输,通过研究改进型的小波变换算法,提出了一种基于小波变换的行列并行计算方法,并依托新的算法进行了图像处理部分的硬件结构设计.设计编码仿真实验对新方法和传统方法进行了对比,结果表明:该方法能够有效减少图像处理过程中的内存占有量,能够依托较小的硬件规模实现图像的高分辨率与高速传输.

In order to improve the image resolution and the image transfer rate of multi-function photography monitor, the improved wavelet transformation was researched and the new method ＂row-column parallel calculation depends on WT＂ was put forward. Based on the new method the hardware design was completed to optimize the image conduct. The new method was contrasted with the former one and the results showed that the new method could accomplish the image resolution with a smaller hardware scale.
