A Clustering and Selection Method using Wavelet Power Spectrum
In this paper, we consider the data mining problem of gene selection based on expression data and propose a method based on wavelet power spectrum. Wavelet power spectrum of the data has been analyzed and on the basis of the observations, a parameter was defined and used to select the features. Our proposed method has been applied on three types of cancer datasets. The results are in comparable...
متن کاملAutomatic Number Plate Recognition Using Haar Wavelet
The tenacity of this paper is logical investigation of prevailing ANPR system research by cataloguing existing methods analyzing and equate old and new techniques. Automatic number plate recognition is a technique to read character from image and isolate number using various processes and practices. Automatic number plate credit is a image processing techniques. In this paper we used efficient ...
متن کاملImage quality measurement using the Haar wavelet
The traditional mean-squared-error (MSE) or peak-signal-to-noise-ratio (PSNR) error measures are mainly focused on the pixel-by-pixel diierence between the original and compressed images. Such metrics are improper for subjective quality or delity assessment, since human perception is very sensitive to correlations between adjacent pixels. In this work, we explore the Haar wavelet to model the s...
متن کاملThe Feature Selection based Power Quality Event Classification using Wavelet Transform and Logistic Model Tree
This paper presents a new power quality event classification technique using wavelet transform and logistic model tree. The proposed method uses the samples of three cycle duration of three line voltage of power quality events. The features of these samples are obtained by using the wavelet transform and a few different feature extraction techniques. The sequential forward selection method base...
متن کاملEnhanced Fractal Image Compression using Haar Wavelet
Fractal image compression offers a high compression ratio with extremely short decompression time. However, it suffered from long compression time. In this paper, a new block classification method based on the Haar wavelet transform is introduced. When used in conjunction with our domain block pool reduction scheme, the enhanced method can improve the speed of compression over 50 times with min...
