Examples
Crop 3-D Volume
Load a 3-D volume into the workspace.
D = load('mristack');
V = D.mristack;Display the image.
fullViewPnl = uipanel(figure,'Title','Original Volume'); volshow(V,'Parent',fullViewPnl);
Crop the volume using imcrop3, specifying the size and position of the cuboidal crop region.
Vout = imcrop3(V,[30 40 10 100 100 10]);
Display the cropped image.
fullViewPnl = uipanel(figure,'Title','Cropped Volume'); volshow(Vout,'Parent',fullViewPnl);
Crop 3-D Image Volume Using Fixed Off-Center Spatial Extent
Load a 3-D MRI image. Use the squeeze function to remove any singleton dimensions.
S = load('mri.mat','D'); volumeData = squeeze(S.D);
Display the image.
fullViewPnl = uipanel(figure,'Title','Original Volume'); volshow(volumeData,'Parent',fullViewPnl);
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.
fullViewPnl = uipanel(figure,'Title','Cropped Volume'); volshow(croppedVolume,'Parent',fullViewPnl);
Center Crop 3-D Image to Target Size
Load a 3-D MRI image. Use the squeeze function to remove any singleton dimensions.
load mri;
D = squeeze(D);Display the image.
fullViewPnl = uipanel(figure,'Title','Original Volume'); volshow(D,'Parent',fullViewPnl);
Specify the target size of the cropping window.
targetSize = [64 64 10];
Create a center cropping window that crops the specified 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 in a display panel.
fullViewPnl = uipanel(figure,'Title','Cropped Volume'); volshow(Dcrop,'Parent',fullViewPnl);
