Functions§
- Convolves an image with the
HORIZONTAL_PREWITT
kernel to detect horizontal gradients. - Convolves an image with the
HORIZONTAL_SCHARR
kernel to detect horizontal gradients. - Convolves an image with the
HORIZONTAL_SOBEL
kernel to detect horizontal gradients. - Returns the magnitudes of gradients in an image using Prewitt filters.
- Computes per-channel gradients using Sobel filters and calls
f
to compute each output pixel. - Returns the magnitudes of gradients in an image using Sobel filters.
- Convolves an image with the
VERTICAL_PREWITT
kernel to detect vertical gradients. - Convolves an image with the
VERTICAL_SCHARR
kernel to detect vertical gradients. - Convolves an image with the
VERTICAL_SOBEL
kernel to detect vertical gradients.
