What do we know about the shape? Is the triangle always in roughly the same location and roughly the same size? Does the shape bulge upwards (like this one does) near the "opening" for all images? Is the bottom always sloping? Can you post two or three more images so we can see what kind of variety we need to plan for? I came up with an algorithm that works for this image but I don't know if it would work for any other image.

Here is the algorithm
- crop the region 1 and find min/max x
[m,n] = size(step1);
[~,x1] = find(step1(:,1:n/2),1,'last');
[~,x2] = find(step1(:,n/2:n),1,'first');
a_value = x2-x1;
- crop region 2
[~,x] = find(step2);
b_value = x(end) - x(1);
- region 3
[y,~] = find(step3);
h_value = max(y) - min(y);
