Computer Vision Fundamentals

Study Notes

Computer Vision

Definition: Computer Vision is a field of Artificial Intelligence (AI) that focuses on enabling computers to interpret and understand visual information from the world.

Key Applications:

Image Recognition: Identifying objects, people, and scenes within images.
Object Detection: Locating specific objects within images or videos.
Image Segmentation: Dividing images into their constituent parts or objects.
Facial Recognition: Identifying individuals based on their facial features.

Techniques:

Convolutional Neural Networks (CNNs): Designed to process data with grid-like topology, such as images.
Image Processing: Enhancing, transforming, or manipulating images to prepare them for analysis.
Deep Learning: Using neural networks to learn complex patterns in images.

Types of Computer Vision:

Traditional Computer Vision: Focuses on rule-based methods and hand-crafted features.
Deep Learning-based Computer Vision: Employs neural networks to learn features and make predictions.

Real-World Applications:

Self-Driving Cars: Computer vision enables vehicles to detect and respond to their surroundings.
Medical Imaging: Computer vision helps analyze medical images, such as X-rays and MRIs, to diagnose diseases.
Surveillance Systems: Computer vision is used in facial recognition, object detection, and tracking.
Quality Control: Computer vision is used to inspect products on production lines.

Challenges:

** Occlusion**: Objects may be partially or fully obscured, making detection and recognition challenging.
Variability in Lighting: Changes in lighting can affect image quality and interpretation.
Image Noise: Random variations in image data can impact analysis accuracy.

Future Directions:

Edge AI: Deploying computer vision models on edge devices, such as smartphones or cameras, for real-time processing.
Explainability: Developing techniques to understand and interpret computer vision models' decisions.
Multimodal Fusion: Combining computer vision with other AI modalities, such as natural language processing or speech recognition.
