Hello, could you tell me how the density map is generated

[zhiyuanyou]

Hi～

Could you give me more information about this density map?

[vasanth4224]

Dear admin,
How to generate density map in crowd using pretrained model?

Please read Sec. 1.4, Sec. 1.4 4), & Sec. 1.1 in README. You should run eval.sh or eval_torch.sh under this directory: https://github.com/zhiyuanyou/SAFECount/blob/main/experiments/Mall/ for evaluation and visualization.

If your question is about the implementation details of visualization, you can see: https://github.com/zhiyuanyou/SAFECount/blob/main/utils/vis_helper.py

bro, could you please help me with this error?

Please see Sec. 1.1 in README, which writes in detail:

• cd the experiment directory by cd experiments/Mall
• eval by running sh eval_torch.sh 1 0 with the format of sh eval_torch.sh #NUM_GPUS #GPU_IDS.
