Add in the convenience and power of Perl, but without all the special cases and magic conversions. Wrap it up in a clean syntax based in part of Eiffel, and add a few ... http://www.programminglearn.com/578/programming-in-ruby During the preparation of this tutorial, I found that almost all the textbooks on digital image processing have a section devoted to the Fourier Theory. Most of those describe some formulas and algorithms, but one can easily be lost in seemingly incomprehensible mathematics. http://www.programminglearn.com/575/tutorial-on-fourier-theory IPL/C++ (image processing library C++ edition) is a result of two things: the need of useful common image processing routines, and the frustration of not being able to find a satisfactory and free one. http://www.programminglearn.com/573/image-processing-library-c-edition-v12-introduction-tutorial-and-user-guide Image analysis combines techniques that compute statistics and measurements based on the gray-level intensities of the image pixels. You can use the image analysis functions to determine whether the image quality is good enough for your inspection task. Also, you can analyze an image to understand its content and to ... http://www.programminglearn.com/571/image-analysis-and-processing-tutorial
