Hierarchical image gathering technique for browsing surveillance camera images

We propose an image gathering and display method for efficient browsing of surveillance camera images. The proposed method requires large cost to inspect lengthy image sequences taken by a surveillance camera. The proposed method involves generating a still image by gathering the moving parts from image sequences captured by a fixed camera. The gathered images are generated for several intervals of time and are displayed hierarchically. A user can easily browse the scene by observing the images with moving parts. Since detection and recognition of the target objects are performed by a human operator, efficient and reliable browsing can be established.
