Discrete Wavelet Transform is a data transformation method that represents in the time domain and frequency domain. This appears to overcome weakness of Fourier transform which only able provide one information limited certain windowing . The type wavelet used Haar Wavelet. Identification periodicity using Periodogram analysis with Fisher's Test statistics. transformed decomposed into two compo...

The basic ideas of the wavelet transformation are sketched. Some applications in (statistical) physics are indicated. nal draft (2.2.96) (submitted to COMPLEXITY)

The wavelet transformation borrowed from signal analysis compresses and analyses the correlationinformation obtained from complex reaction processes in a new way. It reveals information on scaling and clustering.

In the image fusion scheme presented in this paper, the wavelet transforms of the input images are appropriately combined, the new image is obtained by taking the inverse wavelet transform of the fused wavelet co-efficients. The idea is to improve the image content by fusing images like computer tomography (CT) and magnetic resonance imaging (MRI) images, so as to provide more information to th...

Image registration plays an important role in the diagnosis of dental pathologies such as dental caries, alveolar bone loss and periapical lesions etc. This paper presents a new wavelet based algorithm for registering noisy and poor contrast dental x-rays. Proposed algorithm has two stages. First stage is a preprocessing stage, removes the noise from the x-ray images. Gaussian filter has been u...

-Steganography is a term used for covered writing. Steganography can be applied on different file formats, such as audio, video, text, image etc. In image steganography, data in the form of image is hidden under some image by using transformations such as ztransformation, integer wavelet transformation, DWT etc and then sent to the destination. At the destination, the data is extracted from the...

While visual texture classification is a widely-researched topic in image analysis, little is known on its counterpart i.e. the haptic (touch) texture. This paper examines the visual texture classification in order to investigate how well it could be used for haptic texture search engine. In classifying the visual textures, feature extraction for a given image involving wavelet decomposition is...

PQ analysis for detecting power line disturbances in real-time is one of the major challenging techniques that are being explored by many researchers. In order to understand the causes of electronic equipment being damaged due to disturbances in power line, there is a need for a robust and reliable algorithm that can work online for PQ analysis. PQ signal analysis carried out using transformati...
