First Claim
Patent Images
1. A computer-implemented method for processing one or more video frames, comprising:
- obtaining, by a computer, one or more video frames;
generating, by the computer, one or more blobs using the one or more video frames;
identifying each of the one or more blobs to be a respective one of a plurality of different target types, the identifying carried out by the computer; and
employing calibration information to filter, by the computer and based on size, each of the one or more blobs to confirm that each of the one or more blobs is the respective one of the plurality of different target types.

Abstract
Provided is a computer-implemented method for processing one or more video frames. The meth can include generating, by a processor, a change in value of one or more pixels obtained from the one or more video frames; classifying, by the processor, the change in value of the one or more pixels to produce one or more classes of the change in value of the one or more pixels, wherein the one or more classes include one or more of a stationary target, a moving target, a target insertion, a target removal, or a local change; and constructing, by the processor, a listing of detected targets based on the one or more classes.
