The available free libraries are sometimes close, sometimes very far + from “easier”. IM is an unexplored solution and proposed as a simple and clean + one. It is another Imaging tool with a different approach to the many + possibilities in the area. Its organization was designed so it can be used for + teaching Imaging concepts. We invite you to try it.</p> + <p>First we list some libraries mainly target for storage, then some + scientific libraries, and then a small comparsion of IM and those libraries.</p> + <hr> + <p>Here are some free storage libraries:</p> + <p><b>Imlib2</b></p> + + <p class="info">Last Update 2003-09 / Version 1.1.0<br> + <a target="_blank" href="http://www.enlightenment.org/pages/imlib2.html"> + http://www.enlightenment.org/pages/imlib2.html</a> <br> + Language C<br> + Documentation is terrible.

Many + image processing operations.</p> + + <hr> + <h3>Comparsion</h3> + <p>The idea behind IM was to create a toolkit that was not so complex as + OpenCV, neither so big as VTK, but that can be used as a solid base to the + development of thesis and dissertations, as for commercial applications. </p> + <p>As the academic environment is very heterogeneous the IM project choose + some directives:</p> + <ul> + <li>Portability (Windows and UNIX)</li> + <li>C API</li> + <li>Totally Free, Open Source</li> + <li>Focus in Scientific Applications</li> + <li>Easy to Learn</li> + <li>Easy to Reuse</li> + </ul> + <p>Considering these directives there are only a few similar toolkits. Making + some exceptions the following should be mentioned: </p> + <ul> + <li>JAI - Java, Sun.com</li> + <li>VIGRA - C++ / STL Based, University</li> + <li>VIPS - Large Images / Macros, University</li> + <li>VTK - C++ / Huge / Visualization, Kitware.com</li> + <li>OpenCV – “best” similar choice, Intel.com </li> + </ul> + <p>Today OpenCV and VTK are the most professional and complete choices of free + libraries that are similar to IM. But they are more complicated than IM. For + instance VTK it is very large, it has about 700 C++ classes. </p> + <p>Although OpenCV has many resources, its code is very hard to reuse. The + simplicity of the IM code, mainly the image processing routines, make it a + good reference to be reused by other applications extracting only the code + needed with little changes. And can be used as an complement to learn image + processing algorithms and techniques.</p> + <hr> + <p>This page was last updated in Sep 2004.</p> + + +</body> + +</html> |
