Recognition method and recognition device for sheet-type medium

摘要

The present invention relates to a recognition method and a recognition device for a sheet-type medium. The method comprises: step 1, collecting image information; step 2, splitting from the image information collected image information of an object-to-be-recognized; step 3, reconstructing image data of a feature area, extracting a feature on the reconstructed image data, and forming an eigenvector; and, step 4, sending the eigenvector into a standard data-trained classifier, and acquiring a recognition result. The method has an image reconstructed on the basis of feature area prior information, improves image quality, facilitates increased recognition accuracy, and, because only the image area that requires feature extraction is reconstructed, reduces storage space consumption. This not only saves large amounts of storage space and time and increases resource utilization rate, but also increases recognition accuracy and achieves an improved balance between resource and efficiency.

1. A sheet-medium recognition method comprising:
step 1, collecting image information; step 2, separating image information of an object to be recognized out of the collected image information; step 3, reconstructing image data of a feature region, and extracting a feature from the reconstructed image data to form an eigenvector; and step 4, inputting the eigenvector into a classifier trained through standard data to acquire a recognition result.
