CMVS is not working

[Atiq-Hashmi]

Hello HaiyangXu, I am having an issue while running cmvs. Bundler and pmvs are working fine but when I run cmvs on same data it gives me error "Error. Normalized cuts produced an empty cluster: 1 -> 0 1". It has processed 14 images before giving this error and when I opened the image # 15 in visualize folder it was weirdly stretched. It's not using all images I provided as input to bundler as well. I am using 61 images for this experiment.

Here is my log file..
