The present invention relates to a device, system and method for image segmentation of an image of a scene including a subject. To improve the segmentation, the device comprises a receiver (210) configured to receive electromagnetic radiation reflected from a scene including a subject, a polarization unit (220) configured to apply a first polarization on the received electromagnetic radiation to generate first polarized radiation and to apply a second polarization, which is different from the first polarization, on the received electromagnetic radiation to generate second polarized radiation, a sensor unit (230) configured to generate a first image from the first polarized radiation and a second image from the second polarized radiation, and a segmentation unit (250) configured to identify areas of different materials in the scene from a combination of the first and second images.
