Some improvements (center sample) about FCOS (FCOS: Fully Convolutional One-Stage Object Detection).

fcos_plus's Issues

i use conda env,show some error?

/home/Desktop/FCOS_PLUS-master/maskrcnn_benchmark/csrc/cpu/vision.h:3:29: fatal error: torch/extension.h: No such file or directory
#include <torch/extension.h>

能问一下你的code 和 论文中的有区别吗

我看到FCOS的两个版本的论文 都引用了你的 code 地址

Using ctr sampling without "centerness".

Hello,

Thank you for your nice work.
Have you ever tried a model using ctr. sampling that does not have "centerness" branch?
As someone else mentioned in the issue, the centerness score of the sampled center points will be similar.
I wonder whether the "centerness" itself still gives an improvement.

Best,

Ahyun Seo

ious = (area_intersect + 1.0) / (area_union + 1.0) why add1.0

'list' object has no attribute 'resize'???

how to set the dataset ?? i set it by using maskrcnn-benchmark version... please help me !!

How do you implement center sample

has anyone tried ctr. reg? I found it isn't work in my trying and didn't know where the error is

I change the centerness head to regression head, but found it isn't work in my experiment, is someone else did this experiment?

how to train on own datasets?

my datasets have 7 classes.

what's the meaning of "dense locations?"

Is the pretrained model same as "catalog://ImageNetPretrained/MSRA/R-50"?

Does center sample share the same thought with foveabox??

How to set parameter "radius" of center sample

About center sampling

Thanks for your great work! The center sampling method is quite like the sampling method in FoveaBox, is that wright?

does center sampling set the label of un-chossen location to 0?

In many text detection or other anchor-free methods，when we shrink gt to get new "center location", the original zone of gt which not be chosen is set to "ignore". But when I read this code, I find it's set to 0 (neg) directly. do I misunderstand this code or IT IS?
many thanks for you!

What does Multi-scale training mean。。。

I am little confused about the mutil-scale training, do you mean that use the crop or else to enhance the train set and use 2X at the same time? Did the original FCOS use this trick too？or just the 2X.

Request to share models in google drive

Can anyone , please share the trained models(.pth files) in google drive.

about the benefit of center sampling in FCOS

Why does center sampling bring so much improvement? Do you think training with center samples can lead to a better classification branch and regression branch in FCOS?

Moreover, center-ness scores of the center samples could be very close, so using center-ness during inference or not in FCOS_PLUS may lead to similar results?

Can’t calculate the Params and FLOPs of Backbone

I used thop,torchstat and ptflops to caculate the Flops of the model, but all of the results shows there is 0 params and 0 flops in ResNet and FPN. Why did this happen and how can I calucalte the Flops of model correctly. Thank you!
