Image Processing

38 datasets

Computer vision depends on labeled images. The classic benchmarks here are MNIST for handwritten digits, ImageNet in its WordNet hierarchy, Google's Open Images with segmentation masks, the KITTI Vision Benchmark Suite and the Caltech Pedestrian Detection Benchmark. Fine-grained sets include the Oxford-IIIT Pet Dataset, Stanford Dogs and the ETHEC butterfly images, and LILA offers over 10 million labeled images for biology and conservation, many from camera traps.

Other entries cover faces (YouTube Faces, the 10k US Adult Faces Database), human motion (HumanEva), underwater gestures, cervical cytology, 360-degree stereo video and historic newspaper illustrations from Newspaper Navigator. Licences are often non-commercial: KITTI, SVIRO, CCAgT and ETHEC are CC BY-NC, and ImageNet requires accepting its terms. Images themselves may carry separate copyright from the annotations. Face datasets raise consent questions, so check how the photos were collected before training on them.
