Systems and methods for identifying regions within an image having similar continuity values
First Claim

1. An apparatus, comprising:
- a first comparator that compares an edge continuity value of a pixel of each line to edge continuity values of pixels within a first neighborhood of the pixel to generate compare results; and
an assigner that assigns a blob identification of a blob to the pixel based on the compare results to associate the pixel with the blob.

Abstract
A blob identifier uses edge continuity signal to analyze to how to combine the current pixel into an existing or into the background image, or start a new blob. The blob identifier outputs a lists of blob identifiers on a line-by-line basis.
