sam_topo

Segment anything model for topographic data

• easy to costumize: matplotlib-based GUI
• Segment everything first and then interactive segmentation for individual masks

Installation

Please follow the instructions to install segment-anything: https://github.com/facebookresearch/segment-anything.git

Install sam_topo:

git clone https://github.com/ZhiangChen/sam_topo.git
cd sam_topo
pip install .

Run

1. Run GUI for interactive segmentation

python3 gui.py

2. Use the sam_topo library

from sam_topo.gui import SAM_Topo_GUI
sam_topo_gui = SAM_Topo_GUI(img_path='../data/data/sample_data/beach_hillshade_grayscale.png', 
                            sam_checkpoint = "../data/models/sam_vit_h_4b8939.pth", 
                            model_type = "vit_h", 
                            is_cuda=True)

3. Tiff data preprocessing: SAM requires RGB images. sam_topo.preprocessing provides functions to convert tiff data to color or grayscale images.

Demo

1. Segment everything

2. Visualize individaul mask

3. Delete masks

4. Modify individaul mask
