Abstract
Official abstract text for this publication.
A method for identifying objects in a digital image includes tracing chain codes associated with the contour of the object; a series of states is maintained, and the next chain codes in the contour are accepted only if they comply with allowed chain codes for each state. Certain chain codes trigger a transition into a next state. If a disallowed chain code is encountered, the process halts.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for identifying an object in a digital image stored in a computer memory as an array of pixels, the method comprising: traversing the pixels corresponding to a contour of an unknown object in the digital image, wherein traversing comprises: i. loading a next chain-code symbol in the contour into a computer memory; ii. maintaining a current state if the next chain-code symbol in the contour is within a first set of chain-code symbols; iii. trans…
