This paper presents a new method of threshold estimation for ECG signal denoising using wavelet decomposition. In this method, threshold is computed using the maximum and minimum wavelet coefficients at each level. Using this threshold and well known Hard thresholding process, the significant wavelet coefficients from each level are selected and denoised(More)
The ECG digital signal processing evolved in last decade and the need to store and transmit ECG signal data is continuously increasing. This paper involves analysis of an enhanced ECG compression and de-compression method. The method is evaluated on the basis of different compression and quality parameters like compression ratio (CR), percent root mean(More)
Breast cancer is the second leading cause of death for women all over the world. Screening mammography is currently the best available radiological technique for early detection of breast cancer. However the presence of artifacts can disturb the detection of breast cancer and reduce the rate of accuracy in the computer aided detection (CAD) systems. For(More)
The need to store and transmit ECG signal data is continuously increasing. Due to limited storage capacity and limited transmission bandwidth, there is a need to compress ECG signal. This paper involves review of existing ECG compression methods and enhancements are proposed to simplify them for portable ECG recorder. The portable devices or embedded(More)
Mammography is an X-ray imaging technique for diagnosing breast tumour. Segmentation of tumour in the mammogram images are difficult task because they are poor in contrast and the lesions are surrounded by tissue with similar characteristics. In this paper, an automatic detection algorithm is proposed to segment the suspicious masses or lesions. Mammogram(More)
e16013 Background: Nimotuzumab with chemoradiation is found to be efficacious and safe in treatment of locally advanced squamous cell carcinoma of head and neck (LASCCHN). We did retrospective analysis of head and neck cancer patients at single center treated with this combination from December 2006 to December 2010. METHODS Sixteen patients of SCCHN from(More)
Mammography is an X-ray imaging technique for diagnosis breast tumor. Segmentation of tumor in the mammogram images are difficult task because poor contrast and lesions are surrounded by tissue with similar characteristics. Feature extraction from mammogram images is critical task for classification of cancer. In this paper methodology to classify breast(More)
Pneumonia is cause of death of millions of children under 5 years every year. Pneumonia is contagious disease which easily spread through air. Inspite of its severity the conventional methods used for diagnosis of pneumonia are costly and not easily available in resource poor regions. This paper presents a simple tool for diagnosis of pneumonia using cough(More)
Electromyograph (EMG) is a recording of electrical activity of the skeletal muscles. Various muscle related and neuromuscular diseases are diagnosed by analyzing an EMG signals. In this work, neuromuscular diseases such as amyotrophic lateral sclerosis (ALS), myopathy and normal subjects are analyzed by using discrete wavelet transform (DWT). In time domain(More)
