Abstract
Official abstract text for this publication.
Techniques are disclosed that involve the detection of smiles from images. Such techniques may employ local-binary pattern (LBP) features and/or multi-layer perceptrons (MLP) based classifiers. Such techniques can be extensively used on various devices, including (but not limited to) camera phones, digital cameras, gaming devices, personal computing platforms, and other embedded camera devices.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising: detecting a face in an image; determining one or more local binary pattern (LBP) features from the detected face for each of a plurality of local regions by selecting the one or more LBP features from a plurality of LBP features, wherein said selection is based on a boosting training procedure; generating a smile detection indicator from the one or more LBP features for each local region with a multi-layer perceptrons (MLP) b…
