Entropy Based Measure of Camera Focus

Proceedings of the thirteenth Electrotechnical and Computer Science Conference, 2004
A new measure for assessing camera focusing via recorded image is presented in this paper. The proposed measure bases on calculating entropy in image frequency domain, and we call it frequency domain entropy or FDE. First an intuitive explanation of measure is presented, and next tests for some classical properties that such measure should meet are conducted and commented.
