First question is how to upsample to generate the final output heatmap?
Nevertheless, that's only my viewpoints. Experiment results says louder !
I apologize for my ambiguous expression. my question is that the NET 's last layer output is 64x48,which is(W/4,H/4). how about change the last layer output to 256x192,which is (W,H). so that orig-img (W,H)->(W/2,H/2)->(W/4,H/4)->.....->(W/4,H/4)->(W/2,H/2)->(W,H),(pre-heatmap)
pixel to pixel match between orig-img and pre-heatmap will increase AP ?
Thanks for your response .
Excuse me... I'm now confused ... how do you change the last layer output to 256x192 ?
for exmaple 1,add some intermediate layer(W/2,H/2) by (Bilinear upsampling / Deconv/Skip-connection ) 2,and(Bilinear upsample / Deconv/Skip-connect) it to(W,H).
emmmm... then I think the above comments are my response... Generally, I tend to think it won't work considering efficiency and effectiveness.
@chenyilun95,Thank you,I get it. I note that most people make the last layer output to 64 64 (Hourglass Net etc.), 6448(yours). so the best practice of last layer output is (W/4,H/4)? Thanks for your response ,I will close this issue.
Hi @chenyilun95,great work! how about generate heatmap size the same as original image (img :256x192 , heatmap: 256x192)? will it increase AP due to pixel to pixel match? Thanks.
