Abstract
Image processing elements forming an image processor for automatic inspection of circuits. Each processing element for performing a thinning algorithm passes along a data bit and a flag bit to each succeeding processing element. The flag bits permit a conditional deletion of a data bit. Within each processing element a feedback bit is used to indicate when a previous bit has been deleted. The skeletonized image is reviewed for identification of circuit geometries and counting the number of separate blobs. A report is generated in response to the identified geometry and blob count.
