The Segmentation configuration as it is in medInria v2.0.1 is just a preview of the canvas on which segmentation algorithms will be added in the future. The only algorithm available as the moment of writing is a manual painting tool.
The configuration itself has a visalisation area in which any type of layout can be used: Single, Multi, Custom. The segmentation can be run on any View. On top of the toolbox container is a slection toolbox, which contains all the segmentation plugins loaded when medInria was started. At the moment only one called Paint Segmentation is available as a preview. Once an algorithm is chosen, its controsl are visible in a specific toolbox.
All the usual view properties are accessible.
The painting tool will allow 2 colors to be used.
However you don't necesseraly need the second colour. It has been added there first as a seed for an other algorithm needing seed points inside and outside a region. Here you may only use 1 color if you wish.
The generated mask will have three values: 0 for non painted values, 1 for green and 2 for red. If you only use green then the value is only one.
Once you are done, you may export the mask to the database.
The Paint Toolbox has several buttons and fields.
Once you have created your database item by clicking on the corresponding button, a mask is usable in the application. However if you want to save it for later use, you are encouraged to save it in the database, or export it to some external storage device.
To do so go to the browser and use the commands there to save or export the data. Be careful to choose a format that allows "unsigned char" values if you try to export it.
