Feature detection (computer vision)

thumb|400px|class=skin-invert-image|Visual comparison of convolution, cross-correlation, and [[autocorrelation. For the operations involving function f, and assuming the height of f is 1.0, the value of the result at 5 different points is indicated by the shaded area below each point. The symmetry of f is the reason f \star g and g*f are identical in this example. ]]
