My final project for the Computational Photography class at GaTech.
Multi-scale image contrast/detail manipulation
Operating on images at multiple scales is conventionally done using multi-scale decompositions, such as the Laplacian pyramid [Burt and Adelson 1983]. Such techniques decompose an image to multiple detail layers at different scales in a pyramid like fashion.
This project demonstrates how a laplacian pyramid based on the bilateral filter [Tomasi and Manduchi 1998; Durand and Dorsey 2002] can be used for exaggerating details in an image.
I made a simple program in OpenCL that allows for interactively manipulating images at 3 different detail layers and the color base layer.

Excerpt from my class slides
The Mac version is more up-to-date (with added pre-smoothing option), and should now run as a drag-n-drop App!
New version 0.7
-Misc internal tweaks
-(updated Mac Only, linux update will come soon)
