Wavelets: Biomedical applications

Abstract

The aim of this paper is to highlight the biomedical applications of wavelet transform and corresponding research efforts in imaging techniques. A brief introduction of wavelet transform and its properties that are vital for biomedical applications touched by various researchers has been discussed. Application of electrocardiography in terms of QRS complex is briefly spotlighted. Recent survey of wavelet expansion in medical imaging is another facet of this paper, which includes biomedical image denoising, image enhancement and functional neuro-imaging, including positron emission tomography and functional MRI.
