This study aims to provide a low cost solar still using locally available materials to meet
small-scale fresh water demand in the coastal, arid and remote regions. In this study a …

Naturally, with the mounting application of biometric systems, there arises a difficulty in
storing and handling those acquired biometric data. Fingerprint recognition has been …

In the present work we analyze the performance of orthogonal and biorthogonal wavelet
filters for image compression on variety of test images. The test images are of different size …

This paper is intended for choosing the wavelet suitable for volumetric image compression
using 3D Discrete Wavelet Transform. Here we will be comparing few of the basic and major …

Wavelet transform combined with the set partitioning coders (SPC) are the most widely used
fingerprint image compression approach. Many different SPC coders have been proposed in …

Image Processing is dealing with images containing lots of points. By Interpolation of these
points to form different curves are taken under consideration in this paper. The curve …

Wavelets are defined as mathematical functions that segment the data into different
frequency levels. We can easily capture the fine and coarse details of an image or signal …

The gigantic and radical developments in the field of Science and Technology and the
associated improvements in the living standards of people demand to protect data to evade …

In this paper we propose a fingerprint image compression method based on the wavelet
transform and SPIHT coder. The proposed method employs the proposed technique of …
