QuickCSF

A fast, adaptive approach to estimating contrast sensitivity function parameters.

This implmentation is based on:

Lesmes, L. A., Lu, Z. L., Baek, J., & Albright, T. D. (2010). Bayesian adaptive estimation of the contrast sensitivity function: The quick CSF method. Journal of vision, 10(3), 17-17.

Special thanks to Dr. Tianshi Lu at Wichita State University for providing a Matlab implemenation of the fundamental algorithm and Dr. Rui Ni at Wichita State University for the motivation.

Dependencies
