A Benchmark Dataset and Evaluation for Non-Lambertian and Uncalibrated Photometric Stereo
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019Classic photometric stereo is often extended to deal with real-world materials and work with unknown lighting conditions for practicability. To quantitatively evaluate non-Lambertian and uncalibrated photometric stereo, a photometric stereo image dataset
