Computer Vision = Field of AI that helps computers understand image
Trains machines to see, interpret, and make decisions from visuals
Works by converting images into numerical (pixel) data
Uses machine learning, deep learning, and pattern recognition
Can detect and identify objects, faces, shapes, text, etc.
- Helps in classifying and labeling what the system “sees”
Object detection
Object detection = Computer vision technique
It can identify objects and locate their position in images
Works by drawing a bounding box around each detected object
Also assigns a class label (e.g., car, person, dog) to each object
Helps computers what and where objects are in a scene
Combines classification + localization in one process
Segmentation
Segmentation means dividing a large group into smaller groups
Each group has similar or common characteristics
Makes it easier to understand, manage, or target the groups
Marketing: Dividing customers based on age, income, interests.
Operating Systems: Splitting a program into memory segment.
Biology: Dividing an animal’s body into repeated segments
Classification
Sorting or grouping items based on shared features or rules
It is used to organize objects, data, organisms, or information
Each group is called a class or category
It helps in easy understanding, searching, and decision-making
Can be used for living things, emails images, documents, etc.
