1. A method of garment image segmentation, in which an image of a garment is cut, separated or segmented from a background image, the method including the steps of: (i) receiving image data, the image data including an image of the garment, and the background image, in which the background image does not include the image of the garment; wherein the image data includes depth information corresponding to when the garment is scanned or imaged to provide the depth information; (ii) using the depth information in a processing system to automatically differentiate pixels in the image data that correspond to the garment from pixels in the image data that do not correspond to the garment; (iii) cutting, separating or segmenting a cut image of the garment from the background image; and (iv) using the cut image of the garment to generate a virtual 3D image of the garment.
