Focus selection or focus stacking for multi-focal images

[MaximLippeveld]

The CZI images have a Z-dimension. The planes in the Z-dimension have to be converted into one plane. This can be done by selecting one plane, either fixed in config or dynamically using a focus metric. Another option is to fuse the planes with focus stacking.

• Selecting a fixed plane with a config entry
• Dynamically selecting a plane per instance using a focus metric
• Fusing the stack with focus stacking
