Beginner friendly: Challenging

Starting a side hustle in Computer Vision for Quality Control Systems would be quite challenging for the average beginner without prior experience or technical skills. This field requires a solid understanding of computer programming, machine learning, and image processing. The setup costs for necessary hardware and software tools can range from $1000 to $5000. It may take around 6 months to 1 year of dedicated learning and practice before seeing any profit. Online resources like specialized courses on platforms such as Coursera or Udemy can help beginners get started, but the complexity of the subject makes it harder than expected for most newcomers. I'd rate it a 1 because the technical knowledge required and the significant time investment make it very difficult for the average person to start earning a profit in this field.
