The example introduced in this article is to use java to obtain the color value of the image, and then we identify the verification code based on the image. This is a basic verification code that can only be recognized.

Some time ago did a model identification of small projects, the idea is to use the K-means algorithm and the word bag model to do.In recent years, the method of image recognition is very much, this way only record my idea of the project, the core idea is K-means algorithm and vocabulary tree.Unfortunately did not do a thorough development of the ideas before the document, can only follow the memory of the g

I personally think that the free java implementation method is the most convenient way to generate Web snapshots. Snapshots of large webpages can be generated. Great! Import the jar package before using the code. Three jar packages: swt-3.6M3-win32-win32-x86.jar, DJNativeSwing-SWT.jar, DJNativeSwing. jar
