High-speed stroboscope for specular reflection removal of DC illumination

Separation between specular reflection components and diffuse reflection components is an important subject in robotics and machine vision. Hence, the author's group has developed a method to separate a diffuse image from an image of high-speed video with specular reflection components. The method is based on an estimation technique based on luminance variation due to flicker of a light with an AC source. However, the method has a serious issue that it is limited for lights with an AC source. This study gets rid of the limitation by implementing a high-speed strobe light to the camera and produce flickers by artificial means. Experimental results show the validity of the proposed method.
