Summary of Video 1 did not include any frames from the second half of the video. After comparing the sequence with that of Video 2, it was noticed that unlike Video 2, Video 1 starts when the person is in the scene. Therefore, the frames from the second half of the video seem 'normal' and not detected as significant frames. Therefore we tried [http://videos.cctvcamerapros.com/security-camera-videos/ppro-9475-box-camera.html Video 3] which similarly to Video1 is shot in day light but starts with no person in the scene. | Summary of Video 1 did not include any frames from the second half of the video.

In this set of experiments, we investigate applications of our algorithm to summarization of surveillance videos. The algorithm is modified to build the feature matrix using only H and S elements in the HSV color space. The sample videos are taken from CCTV Camera Pros
Video 1 shows a day view of a car, someone approaches the car and steals something from inside and runs away. Video 2 is similar but shot at night. For both videos the first frame which is totally dark and the final advertisements are dropped and not processed. From each a %1 summary is produced.
| Video | #Frames | Key Frames | Summary Image |
| #1 | 490 | 2, 4, 7, 146, 200 | summary1.bmp |
| #2 | 540 | 2, 4, 205, 416, 522 | summary2.bmp |
| #3 | 420 | 10, 132, 396, 416 | summary3.bmp |
Summary of Video 1 did not include any frames from the second half of the video. After comparing the sequence with that of Video 2, it was noticed that unlike Video 2, Video 1 starts when the person is in the scene. Therefore, the frames from the second half of the video seem 'normal' and not detected as significant frames. Therefore we tried Video 3 which similarly to Video1 is shot in day light but starts with no person in the scene.
