extracting subvolume in different shapes
显示 更早的评论
Hello all. As we know, by using 'subvolume' function we can extract volume data in cuboid form which is controlled by the limits . I want to ask that, IS there any process with we can extract subvolumes with 'subvolumes' function in different shapes such as - cylinder,sphere,conical etc. ? Thank you :)

Well yes and no. As you probably know, an image must be rectangular. However you can mask the volume by some oddball shape so that everything else is zero, and then you can extract the bounding box. So it will be rectangular but the shape will be surrounded/filled with zeros from the shape out to the boundaries of the image.

The image must have flat sides, like a box. It can't have round sides, like an apple or a cylinder. Though you can have an apple in a box where the apple has some gray levels and the "air" between the apple and the box sides has gray level of zero. Does that analogy work for you???

If you can segment them separately, you can just and the segmented images
binaryIntersections = binarySphere & binaryCylinder;

Them you should get some background in the logical operations such as AND and OR. Try this link: https://www.google.com/?gws_rd=ssl#q=logical+and+matlab
