Gradiant filter in matlab

WebMore precisely, it uses intensity values only in a 3×3 region around each image point to approximate the corresponding image gradient, and it uses only integer values for the coefficients which weight the image intensities … WebInstead, an approximate version of the gradient descent procedure can be applied to adjust the adaptive filter coefficients using only the measured signals. Such algorithms are collectively known as stochastic gradient algorithms which are explained further along with the MATLAB simulation of steepest descent algorithm. II. STEEPEST DESCENT METHOD
