stack is (n, H, W) or (n, H, W, 3) of good images (n >= 1). Features are standardised with the mean and the standard deviation of each dimension over all good patches. With position_weight > 0 the grid position (0..1 in each direction) times position_weight * sqrt(D) is appended, so a patch is compared with good patches from nearby positions (0 = position-free). coreset in (0, 1] is the fraction of patches kept: the greedy k-centre cover picks, from a seeded start, always the patch farthest from the ones already kept, measuring distances in a seeded random projection to proj_dim dimensions (None = exact). The covering radius in that space after the selection is returned: the largest distance from any good patch to the bank. coreset=1 keeps everything (radius 0, no selection, so seed and proj_dim have no effect).
Returns the model: bank (m, D'), mean / std (D), n_total patches, n_memory, fraction, covering_radius, the feature parameters and image_shape.
Raises ValueError for invalid parameters, a feature that is constant over all good patches, or a stack that would exceed the memory guard.
