Question

I had been reading a webpage on Image Compression (Lossy and Non-lossy).

Now this is my problem, I was successful in making a project on Face detection using opencv – however – my Project Guide is not satisfied – my project simply captures the frames from a Capture device [ webcam ] and passes frames in a function to detect the Faces in those frames and outputs the detect frames in Windows.

My Project Guide wants me to implement some algorithm either of image compression or morphing , etc. but was not happy on seeing such heavy usage of the Library –

So what I would like to know – is it possible to code using C or C++ – image compression algorithms? If yes would not the code size be huge? (my project is supposed to be a minor one)

Please help me out, suppose I want to use the RLE compression using C++ how should I go about it?

Answer 1

You want to invent your own image compression or implement one of the standard ones?
( I assume this is for some sort of class/assignment, you wouldn’t do this in the real world!)

You can compress simple images a little using something like Run-Length, especially if you can reduce the number of colours ie. a cartoon or graphic, but for a real photo style image it isn’t going to work – that’s why complex lossy techniques like jpeg or wavelets were invented.
