VANO: 16bit data reading
hi,

For your question below (attached) I need to understand better what 16bit data you are talking about for VANO.

VANO needs to use two images, one is the original image for
segmentation, and one is the mask (labelfield) image.

VANO already supports 16bit mask image, which has only one channel,
but is used as the indexing image to indicate various image objects.
The software automatically detects 16bit (vs 8bit) and opens it.

For the original image for image segmentation, VANO supports 8bit data
(or 3 channels). It is of course possible to support 16bit data, but
it needs a transferring function to convert 16bit to 8bit for display.
There are many possible ways to do so; thus for the simplicity of the
software, I have left that to the user who can convert as a
preprocessing step. Thus there are two solutions which are not hard.
(1) VANO is open src and you can easily add your own transferring
function. (2) tell us what exactly is the transferring function you
want, and when I get a chance I will add it.

best,

Hi,

Is it possible to read and annotate 16-bits data.
In fact, it is possible using V3D, but with VANO, I couldn't find a
way to read correctly 16-bits 3D tif data.

Any hint?

Thanks into advance,
