Image To Enlarge System Design And Implementation

With the development of computer science and digital image processing technology, more and more image processing software are introduced. However, due to be used in a wider field, there is no software can fully apply to any case. So it has the practical value to complete a image enlarging software. The paper describes how to develop a targeted image processing software in the perspective of designing and implementation, meanwhile, wish to provide a little reference for other image processing software development.The system contains the image amplifier module as the major part, but also including the image edge detection and special effects processing modules, etc. As for the amplifier module, the paper gives a detailed description of different method from some perspective, which refers to the amplification theory, numerical implementation and results of analysis. In the amplifier module, there are 4 kinds of methods used in image magnification. While the bilinear and bicubic interpolation have a fast-speed and acceptable-result, the C&E and Self-Snake model, with good connectivity and clear edge, enlarged image more efficient, the disadvantage is the slow speed. The user can measure the relationship between time spent and amplification quality, so that to make their own choices.The system based on the joint programming under VC++2010 and MATLAB environment. Through MFC (Microsoft foundation Class Library), we complete the function between the system interface design and basic image processing. By calling MATLAB as a system plug-in, we can amplify image in MATLAB environment. The menu and dialog box make the system of user interface friendly.
