Abstract

A computer implemented method of performing video surveillance on a computer system, wherein the computer system comprises a video and a display with a graphical user interface, the graphical user interface including a source window to view play back of the video, the surveillance method comprising: determining an area of interest of a frame of the video based upon a selection of the area of interest within the source window, and generating a plurality of windows within the graphical user interface, each of the windows displaying the area of interest of the frame of the video at a point in time, wherein the graphical user interface includes controls to manipulate the playback of the video from a point in time relative to each displayed portion.

Claims

1. A computer implemented method of detecting activity within a video on a computer system, wherein the computer system includes a video and a display with a graphical user interface, the surveillance method comprising:

acquiring a reference frame from the video;

acquiring a comparison frame;

comparing the pixels of the reference frame to the pixels of the comparison fame to detect pixels that have changed;

showing at least a portion of the video on the graphical user interface;

showing the change in pixels on the graphical user interface by coloring the changed pixels with a pre-defined color; and

gradually altering the pre-defined color to reveal the color of the changed pixels prior to the coloring.

2. The method of claim 1, further including the step of determining the brightness of the pre-defined color based upon the number of pixels that have changed.

3. The method of claim 1, wherein the correlation between the brightness of the color and the number of pixels that have changed is determined based upon an input by a human operator.

4. The method of claim 1, including the step of showing the color of the changed pixels prior to the coloring in response to an input by a human operator.

5. The method of claim 1, wherein the reference frame is selected by a human operator.
