Question

MATLAB图像识别问题求助

I=imread('dmi.png')
imshow(I)
I2=imsubtract(I,background)
figure,imshow(I2)
运行出错??? Error using ==> background
MEX level2 S-function "background" must be called with at least 4 right hand arguments

Error in ==> Untitled3 at 5
I2=imsubtract(I,background)
什么原因？

Answer 1

background这个调用函数没设置进去吧

I=imread('dmi.png')
imshow(I)
background=imopen(I,strel('disk',15));
figure,imshow( background)
I2=imsubtract(I,background)
figure,imshow(I2)
