摘要:
为解决传统插值方法对采集的视频图像放大时易出现块效应和细节退化的问题,在高级RISC微处理器(advanced RISC microprocessor,ARM)平台上设计并搭建基于小波变换算法的嵌入式超分辨率复原系统.以ARM CortexTM-A8处理器(S5PV210)为核心搭建硬件平台,采用嵌入式Linux系统搭建软件开发环境,设计基于V4L2接口的视频图像采集程序.最后将基于小波变换的超分辨率复原算法植入系统.实验证明,该系统处理的视频图像,比传统插值方法处理的视频图像取得了更高的峰值信噪比,能够恢复出更多细节信息.
Abstract:
In order to overcome the disadvantage of the traditional methods for magnifying collected video images by interpolation, we design an embedded super-resolution restoration system based on advanced RISC microprocessor(ARM) and a wavelet transform algorithm. The hardware platform is an ARM CortexTM-A8 processor (S5PV210) as the core processor and the software development environment is embedded Linux. We implement a video image collecting program based on V4L2 and a super-resolution restoration algorithm based on wavelet transformation. Experimental results show that the peak signal to noise ratio (PSNR) is better than those processed by frequently used interpolation methods, and more detail in the images can be restored.
