[−][src]Module imageproc::filter
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 Gaussian 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 dimensions to an image. Each output pixel is the median
of the pixels in a |
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. |
sharpen3x3 | Sharpens a grayscale image by applying a 3x3 approximation to the Laplacian. |
sharpen_gaussian | Sharpens a grayscale image using a Gaussian as a low-pass filter. |
vertical_filter | Returns horizontal correlations between an image and a 1d kernel. Pads by continuity. |
