Open Word 2010/13, click the Insert tab and select Picture to add an image to a document. Select the Format tab to open the toolbar in the shot below. On the left of that toolbar there’s the Remove Background option.
Select the Remove Background option. When you select that option, much of the image will probably turn purple as shown below. The purple areas of the image highlight the background that will be cut out of the picture. Those areas of the picture that aren’t purple will be retained.

Alternatively, you can also mark areas to keep on the image. Press the Mark Areas to Keep button on the Remove Background tab. Draw lines with the pencil to remove purple from the image.
When you’ve finished editing, press the Keep Changes option on the Remove Background tab. That will remove all the purple background. It will leave just the selected foreground in the image as below.
