Hi,
My Background: Manager, Designs. Image Processing Expert.
I've implemented k-means algorithm to detect infected areas in a fruit. This was done in Java and in C++. I've also worked on other classification algorithms. Please look at my profile for my complete work and my portfolio for a few sample images.
As far as your project,
1. i'd recommend trying this algorithm in MATLAB. MATLAB is C based and it's primarily to test algorithms with minimal syntax. You can also plot and see data easily.
2. I've also done tutoring for C and Java online and none of my clients have had any issues with my english (i do have an indian accent). We can do a test skype call to see if you can understand me well. K-means algorithm itself is a simple one and should be done in a couple of hours.
Feel free to ask any questions you have, i'll be more than happy to answer.
Thanks for your time and consideration.
Best Regards,
Venkat
