Image Segmentation

Definition

Image segmentation divides an image into multiple regions with semantic meaning. It includes semantic segmentation (pixel-level classification) and instance segmentation (distinguishing individual objects of the same class), and is widely used in medical imaging analysis and autonomous driving.

Usage Example

Automatically segment tumor regions in medical CT scans to assist doctors in diagnosis.

Object Detection

Object detection is a core task in computer vision that not only identifies objects present in an image but also precisely locates them, typically using bounding boxes. YOLO and Faster R-CNN are the leading object detection algorithms.
