Module imageproc::gradients [] [src]

Functions for computing gradients of image intensities.

Functions

horizontal_prewitt

Convolves with the horizontal Prewitt kernel to detect horizontal edges in an image.

horizontal_sobel

Convolves with the horizontal Sobel kernel to detect horizontal edges in an image.

prewitt_gradients

Returns the magnitudes of gradients in an image using Prewitt filters.

sobel_gradients

Returns the magnitudes of gradients in an image using Sobel filters.

vertical_prewitt

Convolves with the vertical Prewitt kernel to detect vertical edges in an image.

vertical_sobel

Convolves with the vertical Sobel kernel to detect vertical edges in an image.
