Image processing system
First Claim
Patent Images
1. An image processing system for recognizing and interpreting scanned images, comprising:
- a facsimile scanner for receiving an optically scanned image and providing an image output representative of a bit map of the image, the facsimile scanner including a connection for connecting to an image source and an optical scanner for optically scanning images;
a memory for storing image related information;
learn form means coupled to the facsimile scanner and the memory for producing a learned form by receiving the image output, learning positional information relating to acceptable mark positions and storing the learned form in the memory;
build key means coupled to the facsimile scanner and the memory for building a key by receiving the image output, correlating mark information in the image output with the learned form and storing the key in the memory;
score marks means coupled to the facsimile scanner and the memory for interpreting marked images in the image output by comparing marked images with the key and the learned form and providing a score output related to the comparison; and
output means for outputting the score output.

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.
