Detailed Description
Manages a pixmap representation of a gabor patch.Can either compute values directly, or can cache the entire patch.

Member Function Documentation
| double GaborPatch::at | ( | int | x, | |
| int | y | |||
| ) | const [inline] |
Returns the gabor patch value at the given coordinates.
If the patch has been cached, then we just lookup the value out of memory, otherwise we compute it.
Definition at line 77 of file gaborpatch.h.
| void GaborPatch::fillCache | ( | ) |
Force the entire patch to be cached.
As usual, this is a space-time tradeoff... using the cache will make at() lookups faster, but will obviously expend more memory to do so.
