Description: This paperpresent a data-driven, unsupervised method for unusual
scene detection from static webcams. Such time-lapse
data is usually captured with very low or varying framerate.
This precludes the use of tools typically used in
surveillance (e.g., object tracking). Hence, our algorithm
is based on simple image features. This paperdefine usual scenes
based on the concept of meaningful nearest neighbours instead
of building explicit models. To effectively compare
the observations, our algorithm adapts the data representation.
Furthermore, This paperuse incremental learning techniques
to adapt to changes in the data-stream. Experiments on several
months of webcam data show that our approach detects
plausible unusual scenes, which have not been observed in
the data-stream before.

Description: In this thesis we present an operational computer vision system for real-time detection and tracking of human motion. The system captures monocular video of a scene and identifies those moving objects which are characteristically human. This serves as both a proof-ofconcept and a verification of other existing algorithms for human motion detection. An approach to statistical modeling of motion developed by Y. Song is coupled with a preprocessing stage of image segmentation and point feature tracking. This design allows a system that is robust with respect to occlusion, clutter, and extraneous motion. The results of experiments with the system indicate the ability to minimize both false detections and missed detections.
