Coding of fingerprint images using binary subband decomposition and vector quantization
(SPIE, 1998-01)In this paper, compression of binary digital fingerprint images is considered. High compression ratios for fingerprint images is essential for handling huge amount of images in databases. In our method, the fingerprint ... -
Linear/nonlinear adaptive polyphase subband decomposition structures for image compression
(IEEE, 1998-05)Subband decomposition techniques have been extensively used for data coding and analysis. In most filter banks, the goal is to obtain subsampled signals corresponding to different spectral bands of the original data. ... -
Polyphase adaptive filter banks for subband decomposition
(IEEE, 1998-05-06)Subband decomposition is widely used in signal processing applications including image and speech compression. In most practical cases, the goal is to obtain subband signals that are suitable for data compression. In this ... -
Subband coding of binary textual images for document retrieval
(IEEE, 1996)Efficient compression of binary textual images is very important for applications such as document archiving and retrieval, digital libraries and facsimile. The basic property of a textual image is the repetitions of small ...
