nima.generat

Generate mock images.

Functions:

gen_bias([nrows, ncols])	Generate a bias frame.
gen_flat([nrows, ncols])	Generate a flat frame.
gen_object([nrows, ncols, min_radius, ...])	Generate a single ellipsoid object with random shape and position.
gen_objs([params, seed])	Generate a frame with ellipsoid objects; random n, shape, position and I.
gen_frame(objs[, bias, flat, sky, noise_sd, ...])	Simulate an acquired frame [bias + noise + flat * (sky + obj)].

Classes:

ImageObjsParams([max_num_objects, nrows, ...])
