FastSAM: A Fast and Accurate Instance Segmentation Model


FastSAM is a recently released instance segmentation model that offers a powerful combination of speed and accuracy. It is based on the SAM model developed by Meta AI, but FastSAM is specifically designed to be significantly faster while maintaining comparable accuracy.

How FastSAM Works

FastSAM follows a two-step process to achieve instance segmentation:

  1. Object Detection: FastSAM first detects objects in an image using the SAM object detection algorithm. It divides the image into a grid of cells and predicts the bounding boxes and class labels for each object in the grid.
  2. Segmentation: Once the objects are detected, FastSAM utilizes a segmentation algorithm to create a mask for each object, defining the boundaries of the object in the image. The mask is a binary image that assigns a value of 1 to pixels belonging to the object and 0 to pixels outside the object.

Benefits of FastSAM

FastSAM offers several benefits:
