An interactive interface for using OpenCV's GrabCut algorithm for image segmentation.

Overview

Interactive GrabCut

An interactive interface for using OpenCV's GrabCut algorithm for image segmentation.

Setup

Install dependencies:

pip install numpy opencv-python

Usage

python interactive_grabcut.py images/car.jpg masks/car.png

Controls

First, select a bounding box around the object being segmented:

q: quit/done.
r: reset.
left-click-down: start bounding box.
left-click-up: end bounding box.

Mark foreground and background regions on the image. Press g to re-run GrabCut:

q: quit/done.
r: reset.
f: Switch to marking foreground.
b: Switch to marking background.
u: undo.
g: Re-run GrabCut segmentation.
left-click-down: start marking region.
left-click-up: end marking region.
