Abstract

In many circumstances software processing is the best and suitable way of improving image contrast, hence image quality. Different biomedical instrumentation and apparatuses encompass post processing units capable of optimal outcomes. However, in particular cases, especially for contour analysis, the above outcomes are not sufficient. Therefore, an alternative can be envisaged in designing image enhancer and intensifier to compensate image processing limitations. This aspect is very important regardless of computational costs of this alternative. This paper proposes some criteria of design image enhancer and intensifier for biomedical applications. Moreover, the hardware has been used for improving the quality of cardio-vascular image constrast with acceptable outcomes. The images come from different instrumentations, namely, diagnostic ultrasound and echocardiograph. In addition, a specific algorithm has been implemented by means of a variational approach based on Mumford & Shah functional to solve the magnification or zooming problem for a given digital image. The numerical solution of the system of elliptic PDEs associated with the MS functional can provide simultaneously noise suppression, extraction of shape and magnification of the image.
