Title: FOREGROUND OBJECT DETECTION
Abstract:
This disclosure is directed to techniques for performing image segmentation that include capturing an image of an illuminated object, and applying an object region identification algorithm to a difference image based on the image of the illuminated object. In one example, a method includes receiving, by a computing device, a first image of an environment; receiving, by the computing device, a second image of the environment, wherein the second image includes an object not present in the first image of the environment; generating, by the computing device, a difference image from the first image and the second image; identifying, by the computing device, an object region of the difference image; generating, by the computing device and based on the object region of the difference image, a mask; and applying, by the computing device, the mask to the second image of the environment to generate an image of the object.
