基于DSP的小波边缘检测研究

Research on Wavelet edge-detection Based on DSP

借助于TI公司的TMS320VC5416图像处理芯片作为数字图像处理硬件平台,利用CCS开发环境来构建应用程序优化;实现小波多尺度方法来提取边缘,实时得到一系列连续帧的边缘图像。实验结果表明,该方法较好地提高了图像边缘检测的运算速度,满足了实时性要求;能有效地抑制噪声对图像边缘检测的影响,保留了图像边缘细节。

This paper proposed the image processing system which is based on TMS320VC5416,it debug the application by Analysis Tool for CCS software and function optimization, this article realized to improve Image edge-detection of Multi-criteria wavelet. Numerical experiments show that the proposed approach improves the speed of the algorithm greatly and satisfied for probability of real-time occasions. It can also effectively stop the influence of noise for image edge-detection and retention edge-detail of image.
