Abstract
针对移动便捷安检设备快速识别物体的需求，我们设计实现了一种基于TMS320C6678的图像超分辨率增强系统。该系统首先采用双三次插值算法放大原始图像，然后采用暗通道算法进行图像增强，并对暗通道算法中的高斯滤波处理部分进行了OpenMp多核加速处理。实现结果表明，增强后的图片特征清晰，便于观察；且利用多核DSP增强后的时间缩短，相当于单核的0.49倍。 To meet the demand of mobile security inspection equipment to rapidly recognize objects, an image super-resolution enhancement system based on TMS320C6678 is designed and realized in this paper. This system first uses bi-cubic interpolation to magnify the image, then uses dark channel algorithm to enhance the image, and adopts OpenMp multi-core acceleration processing to accelerate the Gauss filter processing part of the dark channel algorithm. The results show that the enhanced images are clear to be observed. And the processing time is shortened, which is equivalent to nearly half of the single core.
