A Novel Approach of Harris Corner Detection of Noisy Images using Adaptive Wavelet Thresholding Technique
Nilanjan Dey, Pradipti Nandi, Nilanjana Barman
In this paper we propose a method of corner detection for obtaining features which is required to track and recognize objects within a noisy image. Corner detection of noisy images…
Wavelet Based QRS Complex Detection of ECG Signal
Sayantan Mukhopadhyay, Shouvik Biswas, Anamitra Bardhan Roy +1
The Electrocardiogram (ECG) is a sensitive diagnostic tool that is used to detect various cardiovascular diseases by measuring and recording the electrical activity of the heart in…
A Comparative Study between Moravec and Harris Corner Detection of Noisy Images Using Adaptive Wavelet Thresholding Technique
Nilanjan Dey, Pradipti Nandi, Nilanjana Barman +2
In this paper a comparative study between Moravec and Harris Corner Detection has been done for obtaining features required to track and recognize objects within a noisy image. Cor…
Wavelet Based Normal and Abnormal Heart Sound Identification using Spectrogram Analysis
Nilanjan Dey, Achintya Das, Sheli Sinha Chaudhuri
The present work proposes a computer-aided normal and abnormal heart sound identification based on Discrete Wavelet Transform (DWT), it being useful for tele-diagnosis of heart dis…
FCM Based Blood Vessel Segmentation Method for Retinal Images
Nilanjan Dey, Anamitra Bardhan Roy, Moumita Pal +1
Segmentation of blood vessels in retinal images provides early diagnosis of diseases like glaucoma, diabetic retinopathy and macular degeneration. Among these diseases occurrence o…
A Novel Session Based Dual Steganographic Technique Using DWT and Spread Spectrum
Tanmay Bhattacharya, Nilanjan Dey, S. R. Bhadra Chaudhuri
This paper proposed a DWT based Steganographic technique. Cover image is decomposed into four sub bands using DWT. Two secret images are embedded within the HL and HH sub bands res…
