Abstract
The present invention relates to a method for visually detecting and tracking an object through a space. The method chooses modules for a restricting a search function within the space to regions with a high probability of significant change, the search function operating on images supplied by a camera. The method also derives statistical models for errors, including quantifying an indexing step performed by an indexing module, and tuning system parameters. Further the method applies a likelihood model for candidate hypothesis evaluation and object parameters estimation for locating the object.
Claims14
A method for visually locating and tracking an object through a space, comprising the steps of:
- choosing a plurality of modules for restricting a search function within the space to a plurality of regions with a high probability of significant change, the search function operating on images supplied by a camera;
- deriving statistical models for errors, including quantifying an indexing step performed by an indexing module, and tuning system parameters;
- and
- applying a likelihood model for candidate hypothesis evaluation and object parameters estimation for locating the object.
A computer program product comprising computer program code stored on a computer readable storage medium for, for locating and tracking objects through a space, the computer program product comprising:
- computer readable program code for causing a computer to choose a plurality of modules for a restricting search functions within a context to a plurality of regions with a high probability of significant change within the space;
- computer readable program code for causing a computer to derive statistical models for errors, including quantifying an indexing step, and tuning system parameters;
- and
- computer readable program code for causing a computer to apply a likelihood model for candidate hypothesis evaluation and object parameters estimation for locating the object.
