In my opinion, the download link of AHU-Crowd may be wrong. The AHU-Crowd was proposed in paper of Dense crowd counting from still images with convolutional neural networks, not Crowd Saliency Detection via Global Similarity Structure. Moreover, I download the dataset by the download link, which does not contain the point annotations. If someone want to download the AHU-Crowd, you can contact the author of Dense crowd counting from still images with convolutional neural networks. I had tried it, the author is nice to provide the download link.
