CNN_FT: The CNN model fine-tuned on the real image data only.

CNN_Syn: The CNN model fine-tuned on the synthetic images only. This baseline reflects how close the synthetic images are to the real data.

CNN_wo_FT: The features of the pre-trained GoogleNet without fine-tuning. For this baseline, we fix the parameters of all the hidden layers during fine-tuning. In other words, only the output layer is fine-tuned.

Furthermore, we benchmark several commonly used image feature representations for baseline comparison. For each feature representation, we train a one-vs-all multi-class linear SVM classifier on the training set. The hyper-parameters of the SVM are determined via fivefold cross-validation. GIST. The GIST descriptor [177] is computed based on 32 Gabor-like filters with varying scales and orientations. We use the implementation by [177] to extract a 512-D GIST feature, which is a concatenation of averaged filter responses over a 4 × 4 grid.
