centerCropWindow3d

Create cuboidal center cropping window

Syntax

win = centerCropWindow3d(inputSize,targetSize)

Description

win = centerCropWindow3d(inputSize,targetSize) determines the window to crop from a 3-D input image of size inputSize such that the size of the cropped image is targetSize. The coordinates of the window are centered in the input image.

Center Crop 3-D Image to Target Size

Open Live Script

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);
