- 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

- 研究表明,构成K一L变换矩阵的向量也就是ToePhtz矩阵的特征向量。与此同时,离散 余弦变换矩阵逼近于ToePutz矩阵的特征向量矩阵,所以离散余弦变换矩阵与自然图像的 K一L变换矩阵十分相似。经过离散余弦变换后的变换系数块的协方差矩阵Cy非常接近对角 阵,即除了对角线元素以外,其它很多元素都近似为0,并且在左上角集中了主要能量。这 反映了自然图像大部分区域变化不大,亮度突变只占少数,即图像能量以低频成分为主的特 性。通过变换后的量化,舍弃对视觉效果影响较小的次要信息,可达
