 Build image pyramids
 ====================

-This example shows how to build image pyramids.
+The `build_gauassian_pyramid` function takes an image and yields successive
+images shrunk by a constant scale factor. Image pyramids are often used, e.g.,
+to implement algorithms for denoising, texture discrimination, and scale-
+invariant detection.
