Method and apparatus for improving image retrieval and search using latent semantic indexing
A method of creating an image database and searching the database is disclosed. A term-document matrix that includes at least two different domain features is created. Latent semantic indexing is applied to the term-document matrix to decompose the term-document matrix. Then a plurality of new vectors are added to a decomposed document matrix of the term-document matrix using a fold-in technique to complete the creation of the searchable image database. Consequently, images are retrieved from the image database by providing a query vector. The query vector is compared against each one of a plurality of document vectors of the decomposed document matrix. Finally, a plurality of images that are similar to the query vector are returned

Abstract
A method of creating an image database and searching the database is disclosed. A term-document matrix that includes at least two different domain features is created. Latent semantic indexing is applied to the term-document matrix to decompose the term-document matrix. Then a plurality of new vectors are added to a decomposed document matrix of the term-document matrix using a fold-in technique to complete the creation of the searchable image database. Consequently, images are retrieved from the image database by providing a query vector. The query vector is compared against each one of a plurality of document vectors of the decomposed document matrix. Finally, a plurality of images that are similar to the query vector are returned
