Electrocardiogram (ECG) signal has been widely used for heart diagnoses, but it always mixed with various noises. In this paper, we present a denoising algorithm that can be used for real-life ECG signal to increase signal to noise ratio for accurate diagnoses. Our new algorithm is based on a classical wavelet denoising process, which is taken from the(More)
Despite recent advances in brain research, understanding the various signals for pain and pain intensities in the brain cortex is still a complex task due to temporal and spatial variations of brain haemodynamics. In this paper we have investigated pain based on cerebral hemodynamics via near-infrared spectroscopy (NIRS). This study presents a pain(More)
Heart disease is one of the leading causes of death in human beings. A survey shows every year about 900,000 peoples die due to heart diseases worldwide. Carotid pulse is a pressure signal recorded over the carotid artery as it passes near the surface of the body at the neck. An abnormal carotid pulse called the dicrotic pulse occurs when patients suffer(More)
Indexes used for image quality evaluation are provided as computational models to measure the quality of images in a perceptually consistent manner. This paper presents a novel evaluation index for assessing image qualities. The index is a modification of the existing traditional Structural Similarity Index Measure (SSIM) by adding another factor to reflect(More)
Many algorithms have been developed to find sparse representation over redundant dictionaries or transform. This paper presents a novel method on compressive sensing (CS)-based image compression using sparse basis on CDF9/7 wavelet transform. The measurement matrix is applied to the three levels of wavelet transform coefficients of the input image for(More)
