I am enrolled in undergraduate program of BS(Computer Sciences). Right now, I am in my final year and since our first semester, we are taught C++ and we've been working in C and C++. So, right now, I've full grip over C++ including all of its concepts like Structs, Classes, Inheritance, Polymorphism, etc.
Regarding Image processing (MATLAB), I took Upwork Test of Digital Image Processing and ranked among Top 20%. I've developed a couple of projects that involved Image processing. You can view them in my portfolio. I developed them in MATLAB.
