Abstract:
1. A system comprising: a processor and a memory of a computing device; and at least one module on the computing device configured to cause the processor to: receive an output of a face detector, the face detector detecting faces using Haar features, the output comprising a set of regions that the face detector has determined include faces; extract from each region of the set of regions, at least one descriptor of a not-Haar feature; and send the at least one descriptor of the not-Haar feature to a post-filter classifier placed at a terminating end of a face detection pipeline to categorize the output as a face or false positive, wherein the post-filter classifier is a trained support vector machine, wherein the post-filter classifier is trained using a set of training regions output from the face detector, the set of training regions including regions that do include a face and regions that are mistakenly classified by the face detector as including faces.
