Detailed Description

Algorithms and classes for handling label maps.

Label Maps

A label map is a 2D or 3D image of 8-bit unsigned char where the pixel values indicate a pixel-wise classification of the underlying coordinate. Usually a label map corresponds to another image of the same size in the same coordinate system so that you have a per-pixel correlation/mapping. Generally, any image can be intepreted as a label map. However, the ImFusion SDK will check the Modality of an image: only if an image has the `LABEL` modality, it will consider an image as label map and for instance activate a special render path for the visualization. You can attach a LabelDataComponent to the SharedImageSet holding a label map to store additional information on the label data and configure its appearance in the views.

Label Map Visualization

Both the default slice rendering and direct volume rendering views support a special render path for displaying label maps. This will be activated for any image that has the LABEL LABEL modality set. In this case, the renderer will not evaluate the DisplayOptions2d or DisplayOptions3d, but the LabelDataComponent instead, which carries the individual label colors and visibility flags for individual label values.
