Review Questions

• How does computer vision utilize machine learning to improve image analysis?
  • Computer vision employs machine learning algorithms to enhance its ability to analyze images by learning from vast amounts of visual data. Through training on labeled datasets, these algorithms identify patterns and features within images, enabling the system to recognize objects or actions with greater accuracy. This relationship between computer vision and machine learning allows for continuous improvement over time as the system gains more exposure to diverse image sets.
• Evaluate the impact of advancements in computer vision technology on journalism practices.
  • Advancements in computer vision technology significantly enhance journalism by automating the analysis of visual content, enabling journalists to quickly sift through vast amounts of imagery for relevant stories. For instance, it can help in verifying photos or videos by detecting alterations or identifying subjects within them. These tools enable more efficient news gathering processes and improve fact-checking efforts, thereby enhancing the overall credibility of journalistic work.
• Assess the ethical implications of using computer vision in public surveillance systems.
  • The use of computer vision in public surveillance systems raises significant ethical concerns regarding privacy and civil liberties. While this technology can enhance security measures and crime prevention efforts, it also poses risks of misuse and overreach by authorities. Issues such as mass surveillance without consent can lead to societal distrust and the potential for discrimination against certain groups. Therefore, balancing the benefits of enhanced safety with the protection of individual rights is essential when implementing such technologies.
