hey everyone, i ahope someone can help me with this code, what i am trying to do is plotting a fitting line. my graf is shown, but the fit line, is not where it should be, it is the wrong direction, and the wrong angle, please what i am doing wrong ?
this is my code :
oneRow = binaryImage(k, :);
leftEdge = find(oneRow, 1, 'first'); rightEdge = find(oneRow, 1, 'last');
midpoints(k) = (leftEdge + rightEdge)/2;
%plot the left and right edge plot(leftEdge, k, 'rx','LineWidth',2); plot(rightEdge, k, 'rx','LineWidth',2);
% CENTER POINTS plot(midpoints(k), k, 'yx','LineWidth',2);
X=[1:100]; new_x = linspace(1, 100); coeffs = polyfit(X, midpoints, 1); new_y = polyval(coeffs, new_x); plot(new_x,new_y, '-','LineWidth',2);
any help will be appreciated thanks.
