Image processing on Android - what libraries can I use?

I need it specifically for image distortion (filters, blurring, etc also welcomed ;) ). Do you know some libraries with appropriate license (Apache, MIT, LGPL also), that I can use? Propriety libraries with reason开发者_StackOverflow社区able prices - open to them also. Can be in C also.

thanks in advance, danail

You may want to check out OpenCV which is developed by Intel. It seems to be very mature and well-documented. Of course, it is also open-source.
