How to Outline an Object with Computer Vision
Blog post from Roboflow
Object outlining, also known as segmentation, is a computer vision technique that identifies the precise boundaries of objects within images or videos, enabling applications in various fields such as autonomous vehicles, medical imaging, and image editing. Unlike object detection, which uses bounding boxes to locate objects, segmentation traces the exact pixel-level shape, which is crucial for tasks requiring high precision, like identifying pedestrians for self-driving cars or distinguishing tumors from healthy tissue in medical scans. Modern segmentation models, such as YOLOv8 and SAM3, are capable of delivering high accuracy and speed, although challenges such as occlusion, complex shapes, and hardware limitations persist. These models require balancing the trade-off between computational power and processing speed, especially for real-time applications. Segmentation techniques also facilitate advanced image editing by allowing precise manipulation of individual objects, and improve warehouse inventory management by enhancing object tracking and automation. The exploration of segmentation models like RF-DETR Seg and SAM3 opens up new possibilities for enhancing the accuracy and effectiveness of computer vision projects.
