🧠 Computer Vision: Image Classification and Object Detection
Computer vision, a branch of artificial intelligence, enables machines to interpret and analyze visual data. Among its numerous applications, Image Classification and Object Detection are fundamental tasks.
Image Classification
Image classification involves identifying and categorizing an image into a predefined class or category.
How It Works:
The model takes an image as input.
It processes features such as color, texture, and patterns using convolutional layers in a neural network.
The model outputs a label corresponding to the most probable class.
Applications:
Facial recognition systems.
Disease detection in medical imaging (e.g., detecting tumors).
Identifying species in ecological research.
Key Technologies:
Convolutional Neural Networks (CNNs).
Pretrained models like ResNet, VGG, and MobileNet.
Object Detection
Object detection extends image classification by not only identifying objects within an image but also determining their locations using bounding boxes.
How It Works:
Combines classification and localization techniques.
Outputs the object class and its coordinates (x, y, width, height).
Techniques like selective search and anchor boxes are used to propose regions of interest.
Applications:
Autonomous vehicles (detecting pedestrians, traffic signs, and vehicles).
Retail (inventory tracking, product identification).
Security systems (intrusion detection, crowd analysis).
Key Technologies:
Region-Based CNN (R-CNN), Fast R-CNN, and Faster R-CNN.
YOLO (You Only Look Once) for real-time detection.
SSD (Single Shot Multibox Detector).
Key Differences
Aspect | Image Classification | Object Detection |
|---|---|---|
Output | Single class label per image | Class labels and bounding boxes |
Focus | Entire image as one entity | Identifying multiple objects in an image |
Complexity | Relatively simple | More computationally intensive |
Conclusion
While image classification answers "what is in this image," object detection answers "what objects are in this image, and where are they located?" Together, these technologies enable advanced applications like self-driving cars, healthcare diagnostics, and surveillance systems, driving the evolution of AI-powered solutions.
