Size recognition system with method for determining price of a commodity

摘要

The present system and apparatus use image processing to recognize object size with a scene. The system includes novel image processing apparatus and method to segment one or more object images from a background image of the scene. A processed image (that can be used to characterize size features) of the object(s) is then compared to stored reference images. The object size is recognized when a match occurs. The system can recognize object sizes independent of number of objects present and the objects may be touching each other and overlapping. The system can be trained to recognize object sizes that it was not originally programmed to recognize.
