Cutout: Stroke-based Matting

Use this method to crop images that have a white, gray, or black background. This method can also be used to crop out areas of an object that also belong to the background.

First Application Example — Cropping Objects on White Surfaces: Select your image from album-mode and click the option labeled “Cut Out” in the menu bar.

Section with the calculated segments: The image has now been segmented into separate sections according to their brightness levels, edges and coloration. Now click on the white  background to crop the object.

The object is now perfectly cropped. The selected area now shows a green tint, the background is blue. Now click on the matting-button to remove the background. Then, click "Apply" and choose a new background for your object.

Second Application Example: Combining Inside/Outside Edge Matting with the segmentation-method to flawlessly remove sections from the inside area. Select the Image you would like to work with and click the Cut Out-button. Now choose the Inside/Outside Matting method and select the inside and outside edges as usual. The cropped result now looks like this:

We immediately see that the sky between hat and arm still has to be removed. In addition, a small part of the arm was cut away and needs to be added again.

In order to incorporate the sky-area into the outside-calculation, simply designate this area with the blue segmentation. The green segment selection should now be used to bring back the missing part of the elbow in the cropped result. Clicking "Execute" followed by "Apply" will finalized your edits. The result speaks for itself!
