Create randomized cuboidal cropping window

Syntax

Description

[win](#mw%5Fcdcb0b8c-e3a1-4c9c-bb2f-591986e9a095) = randomCropWindow3d([inputSize](#mw%5Fd104df6c-2bed-4270-9e02-9fe5a528a83c),[targetSize](#mw%5F7389ada8-c42b-482c-b9d7-f3c043a082aa)) 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 selected from a random position in the input image.

example

Examples

collapse all

Read a 3-D MRI volume. Use the squeeze function to remove any singleton dimensions.

load mri; D = squeeze(D);

Display the volume.

Specify the target size of the cropping window.

Create a random crop window that crops the input volume from a randomly-selected position.

win = randomCropWindow3d(size(D),targetSize);

Crop the volume using the random crop window.

Display the cropped volume.

Input Arguments
