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.
Claims18
A computer-implemented method for processing one or more video frames, comprising:
- computing, by a processor, a change in value of one or more pixels obtained from a first video frame and a second video frame 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.
A device for processing one or more video frames, the device comprising:
- a memory containing instructions;
- and
- at least one processor, operably connected to the memory, that executes the instructions to perform operations comprising:
- computing, by a processor, a change in value of one or more pixels obtained from a first video frame and a second video frame 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.
A non-transitory computer-readable storage medium containing instructions which, when executed on a processor, perform a method for processing one or more video frames, the method comprising:
- computing, by a processor, a change in value of one or more pixels obtained from a first video frame and a second video frame 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.
