Embodiment Construction
[0060] This embodiment is to draw a light color artistic effect with a pen for an input pair of static two-dimensional images, and its specific steps are as follows:
[0061] (1) DoG edge extraction
[0062] Convert the original image Input to a grayscale image (such as image 3 ), calculate the gradient of the grayscale image, use the DoG filter to filter along the gradient direction, and amplify the output of the filter along the real edge, that is, accumulate the responses of each filter to obtain F(s).
[0063] F ( s ) = ∫ - T T Input ( l ( t ) ) f ( t ) dt
[0064] In the formula, l(t) is the value of the input image Input on the gradient l...
