TEMPERATURE ARTIFACT CORRECTION

摘要

A system and method of generating a template of at least one artifact for use in image correction is disclosed. An image containing the artifact is generated using at least two homogeneous exposures, each generated at a different detector operating temperature. The local variance of grey values at each pixel position in the image is calculated. Each pixel in the image is then classified. A binary image is generated based on the classification. The template is then formed based on both the binary image and the image data containing the artifact.
