Online courses to learn image processing and recognition?

I am a complete newbie in the field of both image processing/recognition as well as ML in general.

My aim is to learn the fundamentals and then eventually be able to build commercial applications around it. Right now I am a software developer in a consultancy services company and bored of my job to no end. So advice

I googled around quite a lot but would love to hear inputs by people seasoned in the field. (I get it that /r/MachineLearning might not be the best place, so do let me know if any specific subreddits are better suited for this. I also just asked the same thing in /r/compsci ). Thanks for reading!
