  We address the issue of domain gap when making use of synthetic data to train
a scene-specific object detector and pose estimator. While previous works have
shown that the constraints of learning a scene-specific model can be leveraged
to create geometrically and photometrically consistent synthetic data, care
must be taken to design synthetic content which is as close as possible to the
real-world data distribution. In this work, we propose to solve domain gap
through the use of appearance randomization to generate a wide range of
synthetic objects to span the space of realistic images for training. An
ablation study of our results is presented to delineate the individual
contribution of different components in the randomization process. We evaluate
our method on VIRAT, UA-DETRAC, EPFL-Car datasets, where we demonstrate that
using scene specific domain randomized synthetic data is better than
fine-tuning off-the-shelf models on limited real data.
