Instance Segmentation Model Not Covering Entire Image

[SaulZhang]

Dear authors,

Firstly, thanks for your great work.
Recently, I've encountered an issue while utilizing the script detection/image_demo.py to perform inference using the instance segmentation model. In particular, I noticed that the model consistently overlooks a small portion at the base of the images during the detection phase.
As a consequence, the generated mask appears to fail to cover the corresponding areas of the image. I have attached an illustrative image below to give you a visual representation of the problem at hand.
I'm not quite certain whether this issue originates from the model itself or possibly a complication within the visualization scripts. I would highly appreciate your insights into this problem and any potential solutions you could point me towards.
Looking forward to hearing from you.

Best Regards.
