FAQs

You should review their portfolio to see if they have worked on projects similar to yours, involving OpenCV and related technologies. Look for evidence of experience in image processing, computer vision, and specific domains relevant to your project, such as robotics or augmented reality. Additionally, assess their problem-solving skills and understanding of real-time image processing challenges.
Begin with a comprehensive project brief that outlines your objectives, desired outcomes, and specific OpenCV functionalities you need. Schedule an initial meeting to discuss the project in detail, allowing the freelancer to ask questions and provide their insights. Establish clear milestones and deliverables, and agree on a communication plan, including regular updates and methods for feedback throughout the project.
Prepare a technical assessment or a small task related to your project that requires the use of OpenCV's features. This allows you to gauge the freelancer's coding skills and familiarity with the library. Additionally, ask for code samples from previous projects and check for the quality of code, such as clarity, efficiency, and use of best practices in OpenCV.
