Performance Evaluation of Hybrid Dual Tree Complex Wavelet Transform based Signal Denoising Technique

Abstract In this paper, the performance of the signal and denoising techniques using different types of Wavelet Transform techniques is evaluated based on the different performance metrics such as Signal to Noise Ratio(SNR).  A new Complex Wavelet Transform technique called Hybrid Dual Tree Complex Wavelet Transform, has been proposed in this work, so as to […]

A Review on Signature and Logo Identification and Extraction using Automatic Logo Based Document Image Retrieval Methods

Abstract In Present days we are going with paperless environment for the documentation purpose in order to save the lives of trees. The documents may consists of text, symbols, tables, graphs, logos and signatures and other features also. Out of all these features the signature and logos are having their own unique properties in the […]

Satellite Image Classification based on Ensemble Subspace Discriminant method using Random Subspace Algorithm

Abstract Classification of images obtained from satellites is a challenge now-a-days in order to know the information contained by them. This requires the adaption of the present state-of-art classifiers. Correct information can be retrieved only with good classification method. But single classifier may not meet the requirement, so that ensemble techniques are preferable. For classification […]

Denoising of ECG signals using Multiwavelet Transform

Abstract These days, as the rate of heart ailments expanding progressively, electrocardiogram [ECG] an essential apparatus to analyze the different issues relating to heart. Yet, the recorded ECG frequently contains ancient rarities like electrical cable commotion, gauge clamor, and muscle antiquities. Subsequently denoising of ECG signals is vital for exact analysis of heart ailments. To […]
