imcrop3

Load a 3-D volume into the workspace.

load("mristack")

Display the image.

volshow(mristack);

Specify the size and position of the cuboidal crop region. Then, crop the volume using imcrop3.

cropRegion = [30 40 10 100 100 10];
Vcropped = imcrop3(mristack,cropRegion);

Display the cropped image.

volshow(Vcropped);

Load a 3-D MRI image. Use the squeeze function to remove any singleton dimensions.

load('mri.mat','D');
volumeData = squeeze(D);

Display the image.

volshow(volumeData);

Create a Cuboid object and specify the cropping window size in all three dimensions.

c = images.spatialref.Cuboid([30,90],[30,90],[1,20]);

Crop the image based on the Cuboid dimensions.

croppedVolume = imcrop3(volumeData,c);

Display the cropped image.

volshow(croppedVolume);

Load a 3-D MRI image. Use the squeeze function to remove any singleton dimensions.

load mri;
D = squeeze(D);

Display the image.

volshow(D);

Specify the target size of the cropping window.

targetSize = [64 64 10];

Create a center cropping window that crops an image from its center.

win = centerCropWindow3d(size(D),targetSize);

Crop the image using the center cropping window.

Dcrop = imcrop3(D,win);

Display the cropped image.

volshow(Dcrop);
