代码说明:

matlab练习程序(倾斜校正,透视变换) 过去也写过透视变换,当时算法真是弱爆了,我竟然会通过两次变换。不过那引用的三篇文章都是非常好的文章,直到今天我才看明白。所谓的倾斜校正,一定要有标定点,将一个倾斜的矩形变为不倾斜的。因此可以从原四边形四个点和新矩形四个点得到一个变换矩阵,根据这个矩阵再作用到全局图像就可以了。详细原理在这里, 请点击左侧文件开始预览 !预览只提供20%的代码片段,完整代码需下载后查看 加载中 侵权举报

    Go-Back-N ARQ is a specific instance of the automatic repeat request (ARQ) protocol, in which the sending process continues to send a number of frames specified by a window size even without receiving an acknowledgement (ACK) packet from the receiver. It is a special case of the general sliding window protocol with the transmit window size of N and receive window size of 1.
