Hi, is it possible to find the height and width of the object inside an image? I had attached an image with white and black line to find width and height value

Try this,
A=imread('testing.jpg');
AA=rgb2gray(A);
len=max(arrayfun(@(x) length(find(AA(:,x)~=255)),1:800))
bred=max(arrayfun(@(x) length(find(AA(x,:)~=255)),1:800))

Note:
nnz(something)
is simpler and a lot faster to compute than:
length(find(something))
