Implementation of Integer-Based Wavelets Using Java Servlets

摘要

In this paper, we will discuss applications of Java servlets as a web-based tool for illustration of integer-based new-generation wavelets (lifting) techniques used in the Digital Image Processing instructions and research. The graphical user interface of the application designed as part of this project appears as a web page in the browser of the user's choice. This web page displays several options that the user can use to perform the lifting analysis on digital images. The current options are: the choice of lifting scheme, choice of decomposition or reconstruction, and the level of decomposition or reconstruction. Although input/out images can be in various formats, for the purpose of web browsing, all images are stored in JPEG or GIF formats. Also, the front-end of the tool allows users to choose the inverse or forward transform and the location on the local hard disk from/to which images will be read/written.
