encoder as a backbone our part in the FCN so so here the results are reasonably good so if you just use image net features which is you pre train a classifier or an image net and then you fine-tune it on Pascal the results are like seventy eight point two percent for classification and 56 twenty-eight percent for deduction forty eight percent for segmentation and context encoder the fine tuning to pascal classification is not that good it gets only fifty six point five percent which is way lower than supervised but it's
