Abstract
An object detector that includes a number of weak classifiers can be trained using a subset (a 'working set') of training data instead of all of the training data. The working set can be updated so that, for example, it remains representative of the training data. A decision to update the working set may be made based on the false positive sample rate—if that rate falls below a threshold value, an update of the working set can be triggered.
