Temporal noise reduction and local contrast amplification

摘要

The present invention relates to a method for processing images, wherein images scanned by at least one detector device are processed, and to a device for carrying out the method. According to the present invention, an image is produced from a sequence of chronologically successive individual images by temporal averaging of when individual images. During a classification step of the method, structured image areas are identified in an image and high pass filtering occurs in another step of the method in the identified structured image areas of the resulting image. Temporal averaging enables detector noise to be reduced and subsequent high pass filtering, which is previously and selectively limited to structurally recognized images, increases the resolution virtually, thereby enhancing the overall image quality.
