2D IMAGE ANALYZER

摘要

The invention relates to a 2D image analyzer comprising an image scaler, an image generator, and a pattern finder. The image scaler is designed to scale an image according to a scaling factor. The image generator is designed to generate an overview image which has a plurality of copies of the received and scaled image. Each copy is scaled by a different scaling factor. In the process, the respective position can be calculated using an algorithm which takes into consideration a distance between the scaled images in the overview image, a distance from the scaled images to one or more of the boundaries of the overview image, and/or other predefined conditions. The pattern finder is designed to carry out a characteristic transformation and classification of the overview image and to output a position where the searched pattern maximally matches the specified pattern. Optionally, a post-processing device can also be provided for smoothing and correcting the position of local maxima in the classified overview image.
