shanghai tech dataset

[cryax]

Hi can you share your shanghai data set? I downloaded this data set from http://cs-chan.com/downloads_crowd_dataset.html but got a totally different format with your preprocess.

Hi,

You need to write to the original authors for obtaining the ShanghaiTech dataset. The link that you have shared is different from the ones I used in my experiments.

Hi sorry for this mistake.

The dataset can be downloaded from here: Dropbox: https://www.dropbox.com/s/fipgjqxl7uj8hd5/ShanghaiTech.zip?dl=0 Baidu Disk: http://pan.baidu.com/s/1nuAYslz

Hey. I downloaded the shanghaitech dataset via dropbox. I opened the .mat files using scipy.io. However when I print the obtained file after the conversion, the terminal output is a bunch of array elements. Can someone explain me what does that mean? python load_matfile.py {'image_info': array([[array([[(array([[163.48483516, 341.77022977], [211.56475524, 442.02197802], [333.29902098, 517.72227772],
