Review Questions

• How does parallel computing enhance the performance of computer vision applications?
  • Parallel computing enhances the performance of computer vision applications by distributing complex computational tasks across multiple processors or cores. This allows for faster processing of large datasets, such as high-resolution images or video streams. By leveraging parallel architectures, algorithms can run simultaneously, significantly reducing the time needed for tasks like object recognition and scene understanding, which are critical for real-time applications.
• Discuss the challenges faced by computer vision systems in interpreting visual data and how parallel computing could address these issues.
  • Computer vision systems face several challenges when interpreting visual data, including variations in lighting conditions, occlusion of objects, and background clutter that can confuse recognition algorithms. Parallel computing can help address these issues by enabling more sophisticated algorithms to be applied simultaneously across different segments of an image or frame. This distributed approach allows systems to analyze multiple perspectives or features at once, improving overall accuracy and robustness in challenging environments.
• Evaluate the potential societal impacts of advancements in computer vision technology, particularly regarding privacy and security concerns.
  • Advancements in computer vision technology could have profound societal impacts, especially concerning privacy and security. As facial recognition and surveillance systems become more prevalent, there are growing concerns about individual privacy rights being infringed upon. Additionally, the ability to analyze vast amounts of visual data raises questions about data security and the potential for misuse. Balancing technological progress with ethical considerations will be essential to ensure that computer vision contributes positively to society while mitigating risks associated with surveillance and personal privacy.
