This makes it adequate for small-scale speech applications where flexibility is of the utmost importance, e.g. assistive technology for the speech impaired.

This paper proposes a Bag of Visual Words (BoVW) based approach for keyword spotting on the Mongolian historical document images. In this paper, the first step is dividing the scanned Mongolian historical document images into word images by some preprocessing steps, such as connected component analysis, binarization
This paper proposes novel spectral methods for learning latent semantics (i.e. high-level features) from a large vocabulary of abundant mid-level features (i.e. visual keywords), which can help to bridge the semantic gap in the challenging task of action recognition. To discover the manifold structure hidden among mid
