Abstract: | Content-based image retrieval (CBIR) systems traditionally find images within a database that are similar to query image using
low level features, such as colour histograms. However, this requires a user to provide an image to the system. It is easier
for a user to query the CBIR system using search terms which requires the image content to be described by semantic labels.
However, finding a relationship between the image features and semantic labels is a challenging problem to solve. This paper
aims to discover semantic labels for facial features for use in a face image retrieval system. Face image retrieval traditionally
uses global face-image information to determine similarity between images. However little has been done in the field of face
image retrieval to use local face-features and semantic labelling. Our work aims to develop a clustering method for the discovery
of semantic labels of face-features. We also present a machine learning based face-feature localization mechanism which we
show has promise in providing accurate localization. |
