Implement slightly different SegNet in tensorflow, successfully trained segnet-basic in CamVid dataset
for model detail, please go to https://github.com/alexgkendall/caffe-segnet
Due to indice unravel still unavailable in tensorflow, the original upsampling method is temporarily replaced by deconv( or conv-transpose) layer. this model is still under construction, mainly use for personal research
note: seq_slice.py is small script for data preprocessing and can be totally ignored
