1. Visual Results

To access the original image file, please click on the thumbnail. Some comparable results of our method are marked in the red color. By setting the region number k=2 and capturing 600 images, our method can produce better results among the three real transparent objects.

Runtime listed in our paper and this document only includes the matte extraction time, which does not include data acquisition time or the time of loading images into computer memory. Please note that our results obtained by the DFT are ran on one core because of expensive memory cost of the DFT, whereas all other results are ran on 8 cores.
