Wavelet-based Image Enhancement Techniques for Improving Visual Quality of Ultrasonic Images

Medical imaging is concerned with the development of the imaging devices that help to identify different aspects of the tissue and organs based on various properties and reveal new properties of the tissue and internal structure. Ultrasonic devices are frequently used for medical imaging and the images produced by these devices often have to be converted to a form that is better suited for image analysis and understanding, which are referred as ‘image enhancement techniques’. In this paper, three techniques are proposed for edge enhancement, image enlargement and image fusion. All the algorithms have the common goal of improving the visual quality of ultrasonic images and are based wavelets and other image processing techniques. The proposed models were tested vigorously using various test images obtained and the experimental results proved that the proposed models produce significant improvement over the existing traditional systems.
