ABSTRACT:
An image processing system receives a series of pixel elements representative of a scanned image. The system converts the pixel elements into a vector representation of the scanned image. The vector representation of the scanned image is compared with known vector representations. Based upon this comparison, the image processing system performs various functions such as providing an output or controlling the system. The image processing system may be used for mark sense recognition in which mark information is decoded from learned forms based upon a key. An output is provided based upon a comparison between the marks and the key.
