Blending of the different color channels is changed to alter the snake's color channel sensitivity. For instance, we can make snakes sensitive to the excess of blue color, which is useful with our blue background. Skin can then be easily contoured. Snakes are useful in many circumstances, particularly in the presence of high contrast such as bones on CT images. It helps users, but does not replace them, since the user validation of labeling is an important task.
Label is composed of two windows.
The first window shows a 3D view of the voxel map with organs under reconstruction. The voxmap is represented by its bounding box and a plan inside this bounding box. This plan corresponds to a slice inside the voxmap. A scrollbar allows the user to move this plan. The second window shows a 2D view of the current slice with the cross-sectional contour of the object corresponding to this slice.
