    Study Notes

    Computer Vision

    • Definition: A field of artificial intelligence that enables computers to interpret and understand visual information from the world.

    • Key Concepts:

      • Image Processing: Techniques to enhance or manipulate images for analysis (e.g., filtering, edge detection).
      • Feature Extraction: Identifying and describing key attributes of images, such as shapes and textures.
      • Object Detection: Locating and classifying objects within an image or video (e.g., YOLO, SSD algorithms).
      • Image Classification: Assigning a label to an entire image based on its content (e.g., identifying cats vs. dogs).
      • Semantic Segmentation: Dividing an image into parts and classifying each part (e.g., differentiating foreground from background).
    • Applications:

      • Autonomous Vehicles: Using cameras and sensors to navigate and respond to the environment.
      • Medical Imaging: Analyzing X-rays, MRIs, and CT scans for diagnosis.
      • Facial Recognition: Identifying or verifying individuals based on facial features.
      • Augmented Reality: Integrating digital information with the real world through visual overlays.
    • Techniques:

      • Convolutional Neural Networks (CNNs): A deep learning architecture particularly effective for image-related tasks.
      • Transfer Learning: Reusing pre-trained models on new tasks to save time and resources.
      • Generative Adversarial Networks (GANs): Using two neural networks to generate new images based on learned distributions.
    • Challenges:

      • Variability: Handling changes in lighting, perspective, and occlusions in images.
      • Data Quality and Quantity: Need for large, diverse datasets for training effective models.
      • Interpretability: Understanding how models arrive at decisions can be complex.
    • Future Trends:

      • Real-time Processing: Enhancing the speed and efficiency of computer vision applications.
      • Integration with Other AI Fields: Combining computer vision with natural language processing for more contextual understanding.
      • Ethical Considerations: Addressing privacy concerns and biases in image recognition systems.
