Here’s your Learning Path to Master Computer Vision in 2023

Introduction

There are an overwhelming number of resources out there these days to learn computer vision concepts. How do you pick and choose from a multitude of tutorials? Which is worth investing your time in?

If these questions sound familiar, you’ve come to the right place. We understand the pain and effort it takes to go through hundreds of resources and settle on the ones that are worth your time. That’s one of the primary reasons we launched learning paths in the first place.

Until last year, we focused broadly on two paths – machine learning and deep learning. But our community wanted more granular paths – they wanted a structured learning path for computer vision as well.

And that’s understandable. The demand and value of a computer vision expert is sky high in the industry. Specialize in computer vision and it’s different facets, and you will see a plethora of recruiters trying to get their hands on you.

I remember when I started my own computer vision journey. I was referring to multiple resources simultaneously – books, articles (of which there weren’t many at the time), YouTube videos, among other things. It was a scattered path to mastering computer vision.

Hence, I was delighted to get the chance to put together this structured computer vision learning path for you. Before we get into it, let’s understand the framework I’ve put together to streamline your learning journey.

Our Framework for the Computer Vision Learning Path

Each month has a structure to it as well. This is how we have categorized the different aspects you need to know for each month:

• Objective: What will you learn in that month? What are the key takeaways? How will your computer vision journey progress? We mention this at the start of each month to ensure you know where you stand and where you will be at the end of that particular month
• Time Suggested: How much time on average you should spend on that section per week
• Resources to Learn: A collection of the top resources for the computer vision topics you will learn in that month. This includes articles, tutorials, videos, research papers, and other similar resources
