| Abstract: |
The present system and apparatus uses image processing to recognize object size within a scene. The system includes novel image processing apparatus and methods 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.

First Claim:
Show all 5 claims |
We claim:
1. A method for characterizing size features of a commodity, said method comprising the steps of:
- scanning at least one target object illuminated with a light of a first brightness to acquire a first image and scanning said at least one target object illuminated with a light of a second brightness different from said first brightness to acquire a second image, said target objects being produce of a same variety or type and at a same position when said first and second images are acquired, wherein a visual input device is used for receiving a scanned scene image, the scene image including the image of the at least one target object and a background image;
- scanning at least one target object taking a first digitized image of the at least one target object illuminated at a higher level and taking a second digitized image of the at least one target object illuminated at a lower level;
- identifying visual characteristics by segmenting the at least one target object from the background image using a processed scene image generated from a combination of the first and second digitized images;
- identifying visual characteristics associated with said first and second images of the at least one target object in the scene image;
- segmenting the at least one target image from the background image by comparing said first and second images; and
- processing the segmented target image and classifying said at least one target object, by size, using the identified visual characteristics.
