Thanks for your reply Andrew.
Then, let me change my question.
For these Cortex-M processors, is there an alternative libraries (instead of OpenCV) for face recognition
which can be compiled/build with Keil-MDK 5?

Interesting, something called the "ARM Compute Library" is going to become available: www.electronics-eetimes.com/.../1
It will be open source, and it will contain some machine learning and computer vision capabilities. Let's see how much applies to the Cortex-M world vs. Cortex-A with Mali GPU...
