Review Questions

• How does computer vision utilize algorithms to interpret visual data?
  • Computer vision utilizes a variety of algorithms designed to process visual data by breaking down images into their component parts. These algorithms can detect edges, shapes, and colors to identify patterns or objects within the image. By using methods like feature extraction and machine learning techniques, computer vision systems can classify images and make decisions based on the visual information they analyze.
• Evaluate the impact of deep learning on the advancement of computer vision technologies.
  • Deep learning has significantly transformed computer vision technologies by providing more sophisticated models capable of understanding complex visual data. With neural networks having multiple layers, these systems can automatically learn features from raw images without the need for manual feature extraction. This advancement has led to dramatic improvements in accuracy for tasks like object detection and facial recognition, making computer vision applications much more reliable in real-world scenarios.
• Analyze the ethical implications of deploying computer vision systems in public spaces.
  • The deployment of computer vision systems in public spaces raises several ethical concerns, including privacy violations and surveillance. These systems often rely on collecting vast amounts of visual data from individuals without their consent, potentially leading to misuse or unauthorized tracking. Additionally, biases present in the training data can result in unfair treatment or misidentification of certain groups. Therefore, it's crucial to implement robust ethical frameworks and regulations that govern the use of computer vision technology to protect individual rights while ensuring public safety.
