Exploring how SAM and GroundingDino Increase Opportunities to Accelerate Semi- and Fully Automated Bounding Box Data Labeling
Going from a complex segmentation model to a simpler bounding box object detection model using SAM may seem like a bit of overkill, but there are some instances where an object detection model is favored over a segmentation model. For example, if we have a photo of a street with a bunch of pedestrians, a detection model can provide insight into how many people are there, their location in the frame, and how they interact with each other; segmentation masks wouldn’t give us as useful information since they would just be silhouettes of standing or walking people. Another benefit is that object detection models are designed to be more robust to variations in object size, rotation, and aspect ratio, making them ideal for identifying objects with diverse geometries. Lastly, when computational resources are limited, object detection models tend to be less computationally intensive than segmentation models, which can require more processing power and memory to run efficiently.
