Abstract: This paper presents a robust approach to non-rigid object tracking in video sequences. The object to track is described by a 2-dimensional point distribution model whose landmarks correspond to interest points that are automatically extracted from the object and described by their geometrical position and their local appearance. The approach is novel in that we describe the appearance locally instead of using the raw texture information. This provides a natural way to robustly handle partial occlusions. A second contribution is that we present a method that allows to learn the model automatically. Our algorithms have been successfully tested on several video streams taken from soccer games and video surveillance footage. They have been implemented with the aim of achieving near real-time performance.

TL;DR: The problem the authors are addressing in Alvey Project MMI149 is that of using computer vision to understand the unconstrained 3D world, in which the viewed scenes will in general contain too wide a diversity of objects for topdown recognition techniques to work.
The Hungarian method for the assignment problem
TL;DR: This paper has always been one of my favorite children, combining as it does elements of the duality of linear programming and combinatorial tools from graph theory, and it may be of some interest to tell the story of its origin this article.
Active shape models—their training and application
TL;DR: This work describes a method for building models by learning patterns of variability from a training set of correctly annotated images that can be used for image search in an iterative refinement algorithm analogous to that employed by Active Contour Models (Snakes).

TL;DR: An algorithm for tracking multiple targets in a cluttered environment is developed, capable of initiating tracks, accounting for false or missing reports, and processing sets of dependent reports.
