Method and system for video collection and analysis thereof
View Patent ↗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.
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.
