In the code below, I open and crop three images by selecting the four corners of the region of interest, which is a rectangular shape, but because it isn't perfect, a polygon is drawn.
clear varaiables, close all
if ~exist("subject_image_analysis.mlx")
before = "PIC_1596"; white = "PIC_1539"; after = "PIC_1601";
A = imresize(imread(before,'jpg'),1.00);
B = imresize(imread(white,'jpg'),1.00);
C = imresize(imread(after,'jpg'),1.00);
h = drawpolygon('FaceAlpha',0);
hmin = min(h.Position); hmax = max(h.Position);
After this, I would like each image to be cropped further into 8 same sized rectangles (or regions). How can this be achieved using the area in pixels?
Ideally, this would look like 4 regions in the top half and 4 regions in the bottom half, so that each region can be further analyzed individually.
