Functions for filtering images.
Structs
Kernel |
A 2D kernel, used to filter images via convolution. |
Functions
box_filter |
Convolves an 8bpp grayscale image with a kernel of width (2 * |
filter3x3 |
Returns 2d correlation of an image with a 3x3 row-major kernel. Intermediate calculations are performed at type K, and the results clamped to subpixel type S. Pads by continuity. |
gaussian_blur_f32 |
Blurs an image using a Gausian of standard deviation sigma. The kernel used has type f32 and all intermediate calculations are performed at this type. |
horizontal_filter |
Returns horizontal correlations between an image and a 1d kernel. Pads by continuity. Intermediate calculations are performed at type K. |
median_filter |
Applies a median filter of given |
separable_filter |
Returns 2d correlation of view with the outer product of the 1d
kernels |
separable_filter_equal |
Returns 2d correlation of an image with the outer product of the 1d kernel filter with itself. |
vertical_filter |
Returns horizontal correlations between an image and a 1d kernel. Pads by continuity. |
