• The AGIUSEP 2022 Crowd Counting Challenge requires participating algorithms to count persons in each frame.
  • The goal of counting algorithms is to estimate the number of people in an image. We will provide a dataset with pairs of RGBT images. Each algorithm is evaluated through computing the number of people, mean absolute error (MAE) and mean squared error (MSE) between the predicted number of people and ground-truth in evaluation.
