Top Snow Computer Vision Models

The models below have been fine-tuned for various snow detection tasks. You can try out each model in your browser, or test an edge deployment solution (i.e. to an NVIDIA Jetson). You can use the datasets associated with the models below as a starting point for building your own snow detection model.

At the bottom of this page, we have guides on how to count snow in images and videos.

Guide: How to Track Snow Crossing a Line

You can count how many snow have crossed a line using the supervision LineCounter method.

The following code snippet counts the number of snow that cross a line in a video.

To use the snippet below, you will need to run pip install roboflow supervision. Replace the project name and model name with any model trained on Universe, such as those listed above. 

import numpy as np
            import supervision as sv
            import roboflow
            
            SOURCE_VIDEO_PATH = "snow.mp4"
            TARGET_VIDEO_PATH = "snow_out.mp4"
            
            # use https://roboflow.github.io/polygonzone/ to get the points for your line
            LINE_START = sv.Point(0, 300)
            LINE_END = sv.Point(800, 300)
