灰度图矩阵拟合制作三维曲面
显示 更早的评论
我用fgb2gray函数制作了灰度图，但由于灰度是按每个像素点分布的，并不连续。我现在想用灰度图矩阵拟合成三维曲面。
以x为列向量列数y为行向量行数z为灰度值，拟合为三维曲面？
该如何应用和设置程序？

I used the rgb2gray() function to create a grayscale image, but since the grayscale is distributed per pixel, it is not continuous. I now want to fit a 3D surface with a matrix of grayscales.
Let x be the column vector number of columns y for the row vector row number z is the gray value, fit to a three-dimensional surface?
How to apply and set up the program?

Use the surf():
surf(grayImage);
