Abstract
An image recognition process applied to a photograph is preceded by a pre-processing step which identifies parts of the image which are in focus. The recognition process is then limited to those parts. The pre-processing typically operates by creating a measure of high spatial frequency activity and applying a threshold to them.
Chatting, David. (2008). Image processing system/network which performs recognition process only upon regions having higher high spatial frequency content (U.S. Patent No. 7333672). U.S. Patent and Trademark Office. https://idiyas.com/patent/badge/7333672
