Abstract

An alert and tracking system implemented on a computing device with a processor is presented. The system comprises a display with a viewing portion and a raster portion comprising a plurality of rasters. The system also comprises an image receiver configured to receive a first image and a second image, wherein the first image is received before the second image is received. The system also comprises a processing unit. The processing unit is configured to receive the second image. The processing unit is also configured to compare the second image to the first image. The processing unit is also configured to detect a change between the second image and the first image, wherein the detected change is indicative a moving object. The processing unit is also configured to update the viewing portion to display the second image. The processing unit is also configured to update the raster portion, wherein updating the raster image comprises adding a new raster to the plurality of rasters, wherein the new raster comprises a row of pixels corresponding to a compressed view of the image.

Claims

1. An alert and tracking system, implemented on a computing device with a processor, the system comprising:

an image receiver configured to receive a first image comprising a first two-dimensional grid of portions and a second image comprising a second two-dimensional grid of portions, wherein the first image is received before the second image is received;

a display comprising;

a viewing window comprising a third two-dimensional grid of portions; and

an alert and tracking window offset from the viewing window, the alert and tracking window comprising a fourth two-dimensional grid of portions wherein a first dimension of the fourth two-dimensional grid of portions is a first spatial dimension corresponding to a second spatial dimension of the third two-dimensional grid of portions; and

wherein the processor is configured to;

receive the first image and the second image;

detect a change between the second image and the first image and identify a changed portion from one of the second two-dimensional grid of portions that contains the change, wherein the detected change is indicative of a moving object;

update the viewing window to display the second two-dimensional grid of portions in the third two-dimensional grid of portions; and

update the alert and tracking window to display a highlighted portion that spatially corresponds in one dimension to the changed portion displayed in the viewing window.

2. The system of claim 1, wherein the display further comprises a zoom portion configured to display a zoomed portion of the second image.

3. The system of claim 1, wherein updating the viewing window comprises highlighting the detected moving object.

4. The system of claim 1, wherein updating the viewing window comprises providing an indication of a past location of the detected moving object.

5. The system of claim 4, wherein the indication comprises displaying a plurality of past locations of the detected moving object.

6. The system of claim 4, wherein the indication comprises an indication of a speed of the detected moving object.

7. The system of claim 1, wherein the processing unit is configured to update the viewing window and the alert and tracking window in substantially real-time.

8. The system of claim 1, and further comprising:

a storage component configured to store each of the first and second images.

9. The system of claim 8, wherein the processing unit is further configured to, based on the detected change, calculate a location of the detected moving object, wherein the location is stored in the storage component, and wherein the processing unit is further configured to allow a user to review the stored location information for the detected moving object.

10. The system of claim 1, wherein each of the first and second images are part of a video feed.

11. The alert and tracking system of claim 1, wherein the alert and tracking window comprises:

a plurality of highlighted portions that spatially correspond in the one dimension to a number of past locations of the detected moving object, wherein the number of past locations are based on a first spatial resolution; and

wherein the alert and tracking system comprises;

a user actuatable mechanism that allows a user to change the first spatial resolution to a second spatial resolution.

12. A method of displaying movement of a detected object, the method comprising:

receiving an image comprising an indication of the detected object;

comparing the image to a previously-captured image;

detecting, utilizing a processing component, a change, wherein the change comprises detecting that the detected object has moved between a first time, when the previously-captured image was taken, and a second time, when the image was taken;

displaying an indication of the change, wherein displaying comprises generating a plurality of emphasized image portions and displaying the plurality of emphasized image portions in an alert and tracking window; and

displaying the image in a viewing window that is offset from the alert and tracking window spatially in first direction along a first axis such that the plurality of emphasized image portions of the alert and tracking window substantially align with the indication of the detected object in the viewing window in a second axis that is perpendicular to the first axis.

13. The method of claim 12, wherein displaying the image in a viewing window also comprises displaying an indication of a past location of the detected object.

14. The method of claim 12, further comprising:

displaying an indication of a previous change in the alert and tracking window that is offset from the plurality of emphasized image portions in a second direction that is opposite the first direction along the first axis.

15. The method of claim 12, wherein displaying the image in a viewing window also comprises displaying an indication of a projected future location of the detected object.

16. The method of claim 12, wherein the image comprises a frame of a video feed.

17. A tracking system comprising:

a camera configured to capture an image of a moving object;

a computing device with a processor configured to receive the image;

the processor further configured to generate;

a viewing window comprising the image, the viewing window having two spatial dimensions; and

an alert and tracking window comprising an emphasis indication for the moving object in the image wherein the alert and tracking window is offset from the viewing window in a first direction and aligned with the viewing window in a second direction, such that the emphasis indication aligns with a location of the moving object in one of the two spatial dimensions; and

wherein the processor displays the viewing window and alert tracking window on a display.

18. The system of claim 17, and further comprising:

a data storage unit that stores a location of the moving object, calculated by the processor based on additional images of the moving object captured by the camera; and

a playback controls that allow a user to review the stored location.

19. The system of claim 17, wherein the processor is configured to receive and analyze the image in substantially real-time.

20. The system of claim 17, wherein the camera is a video camera.

21. The system of claim 17, wherein the alert and tracking window and viewing window comprise different portions of a single display screen.

22. The system of claim 17, and further comprising a zoom portion.
