Method for detecting a plurality of instances of an object

摘要

An improved object recognition method is provided that enables the recognition of many objects in a single image. Multiple instances of an object in an image can now be detected with high accuracy. The method receives a plurality of matches of feature points between a database image and a query image (102) and determines a kernel bandwidth based on statistics of the database image (104). The kernel bandwidth is used in clustering the matches (106). The clustered matches are then analyzed to determine the number of instances of the object within each cluster (108). A recursive geometric fitting can be applied to each cluster to further improve accuracy.
