Abstract: This paper addresses for the first time, the problem of multi-illumination fusion with crack enhancement. Our models are trained using cycle-consistent losses to combine crack details from several mutually registered multi-illumination images of ceramic tiles, into a single representative image. Using real-world industrial data, we show that the crack locations are enhanced in the fused images, making them easily noticeable for remote inspection, and demonstrate the effectiveness of our method compared to a multi-exposure fusion technique.
