 Download converted weights here:

+Weights from caffemodel were converted with [caffe-tesnorflow](https://github.com/ethereon/caffe-tensorflow), source code of coverter was modified to fit batch normalization, which is annotated as 'BN' in original prototxt

+Interpolation layer is implemented in code as custom layer
+
+## Important
+
+This implementation is not working properly despite calculations are made without errors(output image is very very bad).
+I can't figure out which causes such behavior, so help and proposals are appreciated.
