An Innovative Lossless Compression Method for Discrete-Color Images

An Innovative Lossless Compression Method for Discrete-Color Images Abstract In this paper, we present an innovative method for lossless compression of discrete-color images, such as map images, graphics, GIS, as well as binary images. This method comprises two main components. The first is a fixed-size codebook encompassing 8×8 bit blocks of two-tone data along with […]


Enhanced Ridge Structure for Improving Fingerprint Image Quality Based on a Wavelet Domain

Enhanced Ridge Structure for Improving Fingerprint Image Quality Based on a Wavelet Domain Abstract Fingerprint image enhancement is one of the most crucial steps in an automated fingerprint identification system. In this paper, an effective algorithm for fingerprint image quality improvement is proposed. The algorithm consists of two stages. The first stage is decomposing the […]
