First Claim
Patent Images
1. An apparatus comprising:
- a processor circuit configured to generate a component table while performing a connected component labeling process on a digital image; and
an ID recycle circuit in communication with said processor circuit and configured to minimize a number of entries in said component table generated by said processor circuit, wherein said ID recycle circuit is configured to (i) present a recycled label value as a new ID value for a newly detected object when a label value to be recycled is available and (ii) generate a new unique label value as the new ID value for the newly detected object when no label value to be recycled is available.

Abstract
An apparatus includes a processor circuit and an ID recycle circuit. The processor circuit may be configured to generate a component table while performing connected-component labeling on a digital image. The ID recycle circuit is generally in communication with the processor circuit. The ID recycle circuit may be configured to minimize a number of entries in the component table generated by the processor circuit.

11. A method of connected component labeling comprising:
-
generating a component table while performing a connected component labeling process on a digital image; and minimizing a number of entries in said component table by recycling ID labels no longer associated with objects in said digital image, wherein (i) when a label value to be recycled is available, the label value to be recycled is presented as a new ID value for a newly detected object, and (ii) when no label value to be recycled is available, a newly generated unique label value is presented as the new ID value for the newly detected object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
