对“2.1.bmp”图像操作,将其放大至原来大小的1.5倍,采用双线性插值方法放大。
对“2.1.bmp”绕图像中心逆时针旋转20度,采用双线性插值方法。此题目不要使用imresize和imrotate函数,自己写程序完成。
2.对畸变图像进行矫正:”2.2.bmp”为畸变后的图像,已知畸变后图像上的四个点(118,88)(90,140)(139,168)(168,116)对应畸变前的点分别为为(98,98)(98,158)(158,158)(158,68),用对应点约束法求畸变前

Hough变换利用图像空间和Hough参数空间的点-线对偶性,把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计,然后在Hough参数空间寻找累加器峰值的方法检测直线。例如,图1(a)中的九条线段对应于如图1(b)所示的其Hough参数空间的九个累加器峰值。图1(b)中,Hough参数空间的横纵坐标分别为直线极坐标方程:ρ=x×cos(θ) + y×sin(θ) 的两个参数ρ和θ。九个峰值的ρ和θ值唯一的确定其对应线段所在直线的两个参数。并且线段的长度决定坐标(ρ,θ)处的
