OCT_GUI.Visualization.Heatmap.
calculateHeatmap
(segmentation)[source]¶ Calculating RPEDC distance map from a given segmentation
Parameters: - segmentation: ndarray
given segmentation as tif file
Returns: - heatmap_rpedc: ndarray, int32
2D image of RPEDC distances

OCT_GUI.Visualization.Heatmap.
calculateMetrics
(heatmap, threshold, voxelsize_transversal, voxelsize_axial)[source]¶ Calculating drusen volumes, color-code decreasing by volume, and create list of volumes. There is a bug when it comes to more than 255 drusen (uint8 limit).
Parameters: - heatmap: ndarray
given segmentation as tif file
- threshold: scalar, int
threshold from slider
- voxelsize_transversal: scalar, float
transversal resolution
- voxelsize_axial: scalar, float
axial resolution
Returns: - drusenmap: ndarray, int32
heatmap with colorcoded drusen
