2D Example Meshes

The directory containing the 2D input data is located in the 2D folder of Medical_Imaging_Data.

The image data were acquired from Centers for Disease Control and Prevention

COVID-19-23354

• Input image : Dimensions (3,000x2,000) with spacing (1x1)
• Uniform with Min-Edge = 15: 82,981 triangles
• Adaptive with Min-Edge = 15: 67,920 triangles

Commands to generate meshes :

Uniform with Min-Edge = 15 : Output Mesh

docker run -v $(pwd):/data/ crtc_i2m tessellate2d --input ./Medical_Imaging_Data/2D/COVID-19-23354.tif --uniform --min-edge 15 --output ./COVID-19-23354,uniform,e=15.vtk

Adaptive with Min-Edge = 15 : Output Mesh

docker run -v $(pwd):/data/ crtc_i2m tessellate2d --input ./Medical_Imaging_Data/2D/COVID-19-23354.tif --min-edge 15 --output ./COVID-19-23354,w=0.1,e=15.vtk

Mesh generated based on the images published at Centers for Disease Control and Prevention. For the uniform meshes, the edge-size corresponds to 15 pixels. The adaptive meshes were created by controlling the size of the elements based on the difference in the intensity of the pixels

COVID-19-23311

• Input image : Dimensions (2,460x2,460) with spacing (1x1)
• Uniform with Min-Edge = 20: 47,028 triangles
• Adaptive with Min-Edge = 20: 34,080 tetrahedra

Commands to generate meshes :

Uniform with Min-Edge = 20 : Output Mesh

docker run -v $(pwd):/data/ crtc_i2m tessellate2d --input ./Medical_Imaging_Data/2D/COVID-19-23311.tif --uniform --min-edge 20 --output ./COVID-19-23311,uniform,e=20.vtk

Adaptive with Min-Edge = 20 : Output Mesh

docker run -v $(pwd):/data/ crtc_i2m tessellate2d --input ./Medical_Imaging_Data/2D/COVID-19-23311.tif --min-edge 20 --output ./COVID-19-23311,w=0.1,e=20.vtk

Mesh generated based on the images published at Centers for Disease Control and Prevention. For the uniform meshes, the edge-size corresponds to 20 pixels. The adaptive meshes were created by controlling the size of the elements based on the difference in the intensity of the pixels.
