Image processing |
摘要 |
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. |
