Functions

N_binary_mask(radius, ndim)
binary_mask(radius, ndim)	Elliptical mask in a rectangular array
cosmask(radius)	Sin of theta_mask
gaussian_kernel(sigma[, truncate])	1D discretized gaussian
get_mask(pos, shape, radius[, include_edge, ...])	Create a binary mask that masks pixels farther than radius to all given feature positions.
get_slice(coords, shape, radius)	Returns the slice and origin that belong to slice_image
mask_image(pos, image, radius[, origin, ...])	Masks an image so that pixels farther than radius to all given feature positions become 0.
r_squared_mask(radius, ndim)	Mask with values r^2 inside radius and 0 outside
sinmask(radius)	Sin of theta_mask
slice_image(pos, image, radius)	Slice a box around a group of features from an image.
theta_mask(radius)	Mask of values giving angular position relative to center.
x_squared_masks(radius, ndim)	Returns ndim masks with values x^2 inside radius and 0 outside
