The regular step gradient descent optimization adjusts the transformation parameters so that the optimization follows the gradient of the image similarity metric in the direction of the extrema. It uses constant length steps along the gradient between computations until the gradient changes direction. At...
Is your sobel image the true sobel edge filtered image, or is it the thresholded, skeletonized image returned by edge()? If it's the latter, well, that has only two values. Is sobelImage uint8 or double? You can use cumsum() to find the top 5...

Open in MATLAB Online I used this code on a gradient image and saw pretty good results. I did change one bit as I wanted to display the arrows on every pixel: ii = 1:1:numel(x);% to add an arrow for every pixel I am confused as to what exactly the direction of the...
The gradient descent method is simple to implement through the fmincon function in the MATLAB toolbox. When the objective function is convex, the solution of the gradient descent method is global. Generally, the solution is not guaranteed to be optimal on a global scale, and the speed of the...
