I want to know heatmap value's range

[2p990i9hpral]

I want change heat map range to 0~255 for heatmap visualization.

I guessed heatmap range is 0~1 and tried multiply 255, but it was not.
When multiplied by 255, the heatmap's maximum value was about 30.

pleas let me know about heatmap value's range!

Yon can calculate the max-value and min-value from multi channels of heatmap. I think it is 0~1 after sigmoid function

unfortunately when I saw heatmap value its range is about 0.00000007 ~ 0.1
I can not set a threshold between joints and not joints.
In other words, I can't classify is person exist in image using heatmap

Thank you for your reply and I am sorry to bother you.

Maybe you should install the latest version of dsntnn. This kind of error has not occurred to me before.

I checked the version of my dsntnn. it is already 1.0.1

can you visualize some heatmap results to me

plt.imshow(heatmaps[0, 8].data.cpu().numpy())
plt.show()

according to the visualization results, i think you can use a threshold to filter the low-score keypoint
