I can generate roi using images.roi.Rectangle function, but it is easy to be time-consuming during the adjustment process.
Is there any way to write that allows me to manually adjust the roi size and position in the image, and return the pixel value of the roi adjusted position
close all
I = imread('rice.png'); % your input image
figure, imshow(I);
roi = images.roi.Rectangle(gca,'Position',[80,45,80,100]);

h=drawrectangle();
wait(h);
You must double-click on the rectangle to confirm its position and return control to Matlab.
