在视觉基础应用程序中淡出窗体

方块编码程序 本程序采用了最简单的方块编码对512×512的lena图像进行了编码 运行程序后可以看出，方块取得越大，图像编码后失真越大。-Box coding procedures used in this process the most simple box of 512 × 512 encoding the lena image after the encoding run the program we can see that the box to obtain the greater the greater the distortion image is encoded.

平滑滤波 一般来说，图像的能量主要集中在其低频部分，噪声所在的频段主要在高频段，同时系统中所要提取的汽车边缘信息也主要集中在其高频部分，因此，如何去掉高频干扰又同时保持边缘信息，是我们研究的内容。为了去除噪声，有必要对图像进行平滑，可以采用低通滤波的方法去除高频干扰。图像平滑包括空域法和频域法两大类，在空域法中，图像平滑的常用方法是采用均值滤波或中值滤波，对于均值滤波，它是用一个有奇数点的滑动窗口在图像上滑动，将窗口中心点对应的图像像素点的灰度值用窗口内的各个点的灰度值的平均值代替，如果滑动窗口规定了在取均值过程中窗口各个像素点所占的权重，也就是各个像素点的系数，这时候就称为加权均值滤波；对于中值滤波，对应的像素点的灰度值用窗口内的中间值代替。实现均值或中值滤波时，为了简便编程工作，可以定义一个n*n的模板数组。另外，读者需要注意一点，在用窗口扫描图像过程中，对于图像的四个边缘的像素点，可以不处理；也可以用灰度值为"0"的像素点扩展图像的边缘。下面给出了采用加权均值滤波的图像平滑函数代码和效果图：-smoothing filter general, the image of energy is mainly focused on the low-frequency part of the noise lies mainly in the high-frequency band, which system to extract the vehicle Edge Information has been concentrated in some of its high frequency, therefore, how to remove high-frequency interference at the same time, maintain the edge information, we Institute enforcement of the content. In order to remove noise, it is necessary for smooth images can be used to the low-pass filter to remove high-frequency interference. Image Smoothing in

README for Picturebrowser ========================= The modified files are included as listed in the final report: -alt_ypes.h : header file for io.h -nxview.c: modified this existing, to time the running time of the display -picturebrowser.c: file which handles the logic of buttoons and the driver (button) -hardware (folder): find the project inside and install on the board -jddctmgr.c : modified manager -jdidcint.c: hardware assisted idct transform -Makefile: to compile picturebrowser (you will have to include in romfs to run our project) -io.h -zImage Running our picture viewer: -------------------------- open the project (in hardware folder) with quartus and in programmer install on the board. In the terminal: $ nio2-download -g zImage and the start nios2-terminal $ nios2-terminal at Boot, it detects the USB and run ./pictureviewer Navigate through buttons...enjoy it with moderation:) -README for Picturebrowser ====
