How To Become A Computer Vision Engineer
If you want to become a computer vision engineer, your journey will be filled with many challenges. But don’t worry because you can pull it off with your passion for this field.
1. Get a Strong Foundation
Study first! Once you have a solid knowledge background, you can be confident moving forward.
You should start with a bachelor’s degree in computer science or information systems. These majors provide you with a deep understanding of computer systems and algorithms.
You have many education paths to consider. But whatever you choose, focus on these concepts:
Programming
You need to code when developing computer vision applications. Python is the most popular programming language for computer vision engineers.
C++ is also a good idea. It provides high performance with an extensive library to support machine learning (ML) solutions.
I highly recommend MATLAB. It’s excellent for fast prototyping and generating new ideas. The adaptability to the research environment is another plus.
Image processing methods and tools
Working with image processing is a must. Hence, you need to master image processing methods and tools. After trying tons of them, I like the following options the most:
- TensorFlow: This open-source library is ideal for ML. You can use it to create and manage neural networks. It can also support ML models with complex numerical computation.
- YOLO: I often use this algorithm to spot real-time objects. The core of YOLO is its convolutional neural network.
- Keras: Like TensorFlow, Keras is a free and open-source library. It can help deploy deep learning models.
- PyTorch: As the name suggests, this library aims to support Python Code. You can also use it for image processing and NLP.
Mathematical roots
You must be good at math to become a computer vision engineer. At least, you have to deal well with these foundational mathematics:
- Linear algebra
- Pattern recognition
- Bayesian Probability
- 3D geometry
Computer vision techniques
There are many computer vision techniques to learn. You should start with these first:
- Semantic segmentation: An image has many objects. So, you need semantic segmentation to identify those objects first, then label them into classes. For example, if a picture has five cats, you can segment the cats as a class and name it “cat.”
- Instance segmentation: This concept is completely different from semantic segmentation. All the objects in an image are similar. Thus, you can identify them as distant instances. So, with a picture of five cats, you will segment each cat as an object.
- Object localization: This process occurs when you identify the position of one or more objects in one picture.
- Object detection: After locating the objects, you draw a bounding box around their extent. This technique is “object detection.” It helps you measure the object’s scale and its location in the image.
- Object tracking: A video has moving objects. Thus, you need the object tracking technique to follow them.
- Face recognition: This technique is familiar when you take a picture of yourself or others. It uses deep learning and neural networks to work.
2. Obtain a certificate
You can obtain certifications in computer vision to strengthen your knowledge. There are many online courses to choose from.
Convolutional Neural Networks course (from Coursera)
I have mentioned “neural networks” many times, right? They are important for image processing. So why don’t you dig deeper into this topic?
The Convolutional Neural Networks course from Coursera will teach you how to apply this concept to your visual recognition and detection tasks. The instructors also give tips for writing effective codes for your software.
The course has different sections, each with small questions and assessments to help you follow the program easily. After completing the exercises and assignments, you can earn the certification.
Introduction to Computer Vision (from Coursera)
If computer vision is new to you, try this course. I took it when I first stepped into this industry, and it was amazing.
By the end of the course, you can use Python, OpenCV, and Watson AI to process pictures. You can even handle image classification systems effortlessly.
Moreover, the course gives you free access to cloud environments. Then, feel free to create your computer vision apps there.
Python for Computer Vision (from Udemy)
This course is one of the best options for using Python in computer vision. You can practice with feature matching and face detection techniques in the classes.
In addition, you will study deep learning networks and optical flows. They will surely be your secret weapons when working as a computer vision engineer.
However, this course is for intermediate-level learners. It means you should be familiar with Python before attending the classes.
3. Gain experience
Once you’ve got the techniques, practice using them. Experience will help you become the computer vision engineer that all companies desire.
You can get hands-on experience by joining computer vision projects. You can try these ideas:
