How do you get the position information for images?

Hi!
What a great work. Could you tell me how did you get the pre-trained position information for images?Thansk a lot!

Faster rcnn model can automatically get both the visual features (2048-dim vector) and the position information. The position information about region contains four values: the coordinates (x,y) of left-up point and the width/height of this region.

Hi HaoYang,
I wonder that how do you get the raw region information(x, y, w, h). Did you run Faster rcnn by yourself or get it from other sources? How to align the region information with the precomputed features from SCAN?
Thank you very much.

Hello, Hao Yang. Thanks for your excellent work and code. However, I have some questions about the paper and code. Firstly, I wonder how you transfered the coordinates to 15 dims like your comments describing in model_attention.py, as I know, the coordinates of a box should be 4-dim. For another, in your paper, you suggest that equally the whole image 𝐼 is splited into 𝐾×𝐾 blocks 𝐵, but I have not find this part in your code release.

hello，I also have such doubts. Have you solved them? If it is settled, I wonder if you can leave a contact way to discuss it?

Looking forward to receiving your reply
