Chapter 1: Understanding Computer Vision

For decades, we have been immersed in a world filled with images and videos. The advancements in technology, including cameras and smartphones, have made it commonplace to capture moments and share them with others. Concurrently, researchers and engineers have been striving to enable computers to "see" and extract meaningful information from visual data—this field is known as Computer Vision. It involves endowing machines with the capability to interpret visual information.

General Overview of Computer Vision

Computer Vision is a specific application of Deep Learning that relies on a substantial dataset. The algorithm processes this data to identify patterns, allowing it to recognize or locate objects within images. A common method for achieving this is through Convolutional Neural Networks (CNNs). These networks employ mathematical convolution to break down images into pixels, applying filters to extract pertinent information from those pixels.

This process is iterative; the algorithm continuously revisits the images to minimize loss, similar to other Deep Learning techniques.

Most Common Tasks in Computer Vision

Let's briefly explore some of the fundamental tasks associated with Computer Vision before diving deeper into how to start learning this field.

  1. Image Classification: This task answers the question, "Does this image feature a horse, zebra, or dog?"
  2. Object Detection: A more advanced task, object detection builds upon image classification to determine the presence of a specific class and localizes it using regression algorithms to draw a bounding box around the identified object.

Computer Vision is deeply integrated into our everyday lives, making its presence felt across various sectors: from sports and healthcare (like cancer detection and cell analysis) to agriculture (monitoring crops and animals) and transportation (self-driving cars detecting pedestrians and signs).

Chapter 2: Becoming a Computer Vision Engineer

Many aspiring engineers assume that the path to studying Computer Vision begins with an immediate focus on Deep Learning and its primary architectures. However, it's important to recognize that Computer Vision has a rich history that predates the Deep Learning era.

Key Areas to Focus On:

  • Programming Skills: Proficiency in programming is essential. While both Python and MATLAB are viable options, Python is recommended due to its versatility.
  • Foundational Knowledge in Machine Learning: Before venturing into Deep Learning and Computer Vision, it's crucial to have a solid understanding of Machine Learning principles. Not all Computer Vision challenges are addressed with Deep Learning; traditional methods often utilize libraries such as scikit-learn.
  • Mathematical Proficiency: A strong grasp of math, geometry, and linear algebra is particularly beneficial, especially in traditional Computer Vision approaches. This field often involves concepts related to angles, matrices, and calculus.

Helpful Resources for Learning

Once you've established the necessary skills, consider the following resources that can aid your learning journey:

  1. Introduction to Computer Vision — Georgia Tech: This free course on Udacity explores foundational concepts in Computer Vision, including cameras, angles, light, and feature extraction.
  2. Advanced Computer Vision — deeplearning.ai: Once you have a robust understanding of Machine Learning and mathematics, you can delve into contemporary Computer Vision techniques. Platforms like Udemy and Coursera offer a plethora of courses to choose from.

The first video, "Complete Deep Learning & Computer Vision Roadmap for Beginners," provides a comprehensive overview for newcomers looking to navigate their way through the complexities of this field.

The second video, "How to Learn Computer Vision from Scratch to Become a Computer Vision Engineer," offers valuable insights and tips for those ready to embark on their journey.

Conclusions

Embarking on a career in Computer Vision is a lengthy endeavor; a few courses alone won’t suffice. The key is to continuously build, share, and iterate on your knowledge.
