What are the masters options available for getting into computer vision and image processing research from an electronics background? Having done bachelors in electronics and instrumentation and a research experience in the field of image processing and computer vision and some publications in the same, what are the possible MS options where I can study computer vision and image processing? Can I opt for MS in robotics, computer science, signal processing?

My confusion is regarding the fact that I was a bachelors student in a different field. Would it be difficult for me to change to a masters program in this other field?
There are Masters of Science programs in Computer Visions and even Computer Science that you can definitely look into. I'm not sure if your preference is to attend school online or on campus. I'm not sure of your location or budget either, so this answer will sound quite generic. However, I have included Georiga Tech's program. The Georgia Tech link is just a course in Computer Visions that's part of their Master of Science in Computer Science program. I believe their program is $7,000 (if it hadn't increased) and it's fully online. I've included their online Masters site link.
