A Motion Compensation Algorithm Based on Non-Linear Geometric Transformations and Quadtree Decomposition
In this paper we present an efficient very low bit-rate coder for CIF image sequences at 10 frames/s. The proposed algorithm performs motion compensation using a second-order geometric transformation and a qua...

Multi-view Multi-object Detection and Tracking
Multi-viewtrackers combine data fromdifferent camera views to estimate the temporal evolution of objects across a monitored area. Data to be combined can be represented by object features (such as position, co...

Change Detection for Object Segmentation
Object segmentation based on motion or change detection is the first step in many smart camera applications, such as video surveillance, human computer interaction, and immersive gaming. Efficient and accurate...

Chapter
Recognizing Interactions in Video
Detection and tracking algorithms generates useful information in the form of trajectories from which the behaviors and the interactions of moving objects can be inferred through the analysis of spatio-tempora...

Trajectory Clustering for Scene Context Learning and Outlier Detection
We present a scene understanding strategy for video sequences based on clustering object trajectories. In this chapter, we discuss a set of relevant feature spaces for trajectory representation and we critical...

Simultaneous Detection and Tracking with Multiple Cameras
Tracking targets using multiple cameras is an important processing step for applications such as sports analysis, traffic monitoring, behavior detection and event recognition. The multi-camera tracking problem...
