HAKE-HICO is an improved version based on the HICO dataset released by Shanghai Jiao Tong University. The image files of this dataset use the original image files in the HICO dataset. On this basis, the classification annotations for each image are different from those in the HICO dataset and are re-arranged, including part information such as ankles, knees, hands, shoulders, etc.; action information such as standing, walking, jumping, etc.
