Image retrieval requires a system to find information relevant to a
query which represents images containing faces of the same person appearing in
the query image. In this paper, we aim to build a scalable face image retrieval
system. For this purpose, we develop a new scalable face representation using
Gray level co-occurrence
matrix (GLCM)
features at different orientation
(45,60,90 degrees),gray level and moment invariant features,
orientation histogram features and Law’s texture features. The extracted features are
trained and classified by feed forward back propagation neural network and
Support vector machine
(SVM) classifier to rank the candidate images. The performance of the
designed face image retrieval system will be analyzed in terms of Accuracy and
retrieval rate .The performance of the proposed retrieval system will be
compared with existing system. In this proposed system we aim to build a scalable
face image retrieval system. For this purpose, we develop a new scalable face
representation using both local and global features. In the indexing stage, we
exploit special properties of faces to design new component based local
features, which are subsequently quantized into visual words using a novel
identity-based quantization scheme. We also use a very small Hamming signature
(40 bytes) to encode the discriminative global feature for each face. In the
retrieval stage, candidate images are firstly retrieved from the inverted index
of visual words. We then use a new multi-reference distance to re-rank the
candidate images using the Hamming signature. On a one million face database,
we show that our local features and global Hamming signatures are complementary
the inverted index based on gray level and moment invariant features provides
candidate images with good recall, while the multi-reference re-ranking with
global Hamming signature
leads to good precision.
