We address the problem of normal reconstruction for a transparent object, where the integrated surface is an overall shape of the target object that preserves salient features and fine structures if present on its exterior surface. Such detail-preserving exterior surface representation is adequate for vision and robotics applications where transparent objects are to be grabbed by a robotic arm, or avoided by a navigating robot in a cluttered scene. In our paper, our goal is different from photorealistic rendering or high-accuracy reconstruction of transparent objects, where custom equipment, calibrated and mechanical capture are often deemed necessary to achieve precision as high as to trace the complex refractive light-transport paths exhibited by the target object. On the other hand, when an adequate shape without
