数字图像处理中，灰度图像的放大、缩小，平移和旋转功能实现的源代码，分别采用最近邻插值法和双线性插值方式实现。,Digital image processing, the gray-scale image to enlarge, narrow, pan and rotate functions of the source code, respectively, using nearest neighbor interpolation and bilinear interpolation way.

IMROTATE2 Rotates an image with circular shift. B = IMROTATE2(A,ANGLE) rotates image A by ANGLE degrees in a counterclockwise direction around its center point. To rotate the image clockwise, specify a negative value for ANGLE. It makes the output

实现图像空间旋转，灰度插值操作，插值方法分别是最近邻法和二次线性法。-Achieve the image space rotation, gray-level interpolation operation, interpolation methods are nearest neighbor method and the second linear method.

这是对图片进行旋转的程序，只需设置图片的位置和旋转的角度便可以进行旋转，采用的是最近邻插值算法。-This is a program to rotate the picture, simply set the location of the picture and the angle of rotation can be rotated using the nearest neighbor interpolation algorithm.

分别使用最近邻方法和双线性差值方法实现图像的平移、旋转、缩放-Develop a geometric transform program that will rotate, translate, and scale an image by specified amounts, using the nearest neighbor and bilinear interpolation methods, respectively
