Low resolution images

[mazatov]

I'm trying to run this on low-resolution images that contain one human. The images are about ~ 50x100 pix, so much smaller than the model boxsize. The program doesn't work very well on such low-resolution images. The majority of them do not have joints detected well. Though heatmaps appear to be ok.

I was wondering if someone would have any tips on how to modify the program to perform better on low res images. Thanks.
Here's an example of an image that didn't work.
