We have seen the basics of Image Processing and it’s uses in the 1st post and got started with OpenCV in the 2nd. This post will tell you more about IP using Matlab, the math that is used and that governs the IP algorithms. You might be wondering where math came into the picture right…? (Cause i did too ;))
Everything in IP is based on math too. From every function to every algorithm all use complex mathematical operations to achieve what they do. Even if you merge 2 images, there is an algorithm that is using math to ‘split’ the images into pixels, ‘compare’ each pixels of the 2 and do a weighted ‘addition’! This understanding what goes on behind the scenes is equally important as knowing how to write code. (This is especially for those who thought ‘coding is all I need’ )
If you have Matlab installed then install the image processing and computer vision toolbox. Matlab has a lot of inbuilt functions for IP. View them in the Matlab help, or see here… Computer Vision specialists all make use of in-depth mathematical knowledge to make their algorithms. Every algorithm uses maths. A lot of times the base is Wavelet Transform and fourier transforms. If you’re really interested there are a lot of channels on YouTube that cover the math behind image processing. That’s all for the Image Processing posts, hope it helps you get started !! Comment if there’s any topic you want covered |
