The theoretical bases of Machine Vision provide the groundwork for developing algorithms and systems that can analyze and interpret visual data effectively. The theoretical bases of machine vision include several key concepts and principles like:
- Image Formation: Understanding how images are captured through sensors, including concepts like perspective projection, lens optics, and lighting conditions.
- Image Processing: Techniques for enhancing and manipulating images, such as filtering, noise reduction, histogram equalization, and edge detection.
- Feature Extraction: Methods to identify and quantify relevant features in images, including geometric shapes, textures, and colors, using techniques like contour detection and SIFT (Scale-Invariant Feature Transform).
- Pattern Recognition: Algorithms that classify and identify objects or patterns within images, often using machine learning methods like neural networks, support vector machines, or decision trees.
- Deep learning/Neural networks: Neural networks are computational models inspired by the human brain, designed to recognize patterns and learn from data. Neural networks learn through a process called training, where they adjust their weights based on the error of their predictions using algorithms like backpropagation.
- Computer Vision Algorithms: Fundamental algorithms for tasks such as object detection, segmentation, and tracking, including deep learning approaches like convolutional neural networks (CNNs).
- 3D Reconstruction: Techniques to infer three-dimensional structures from two-dimensional images, involving concepts like stereo vision and depth estimation.
- Geometric Transformations: Theoretical foundations for manipulating image coordinates, including translation, rotation, scaling, and perspective transformations.
- Machine/Deep Learning: Theoretical underpinnings of supervised, unsupervised, and reinforcement learning, which are used to train models for various vision tasks.
- Human Vision Models: Insights from biology and psychology that inform how machines can mimic human visual perception, including color theory and visual attention mechanisms.
