## A novel Region of Interest Extraction Layer for Instance Segmentation |
|
|
|
By Leonardo Rossi, Akbar Karimi and Andrea Prati from |
|
[IMPLab](http://implab.ce.unipr.it/). |
|
|
|
We provide configs to reproduce the results in the paper for |
|
"*A novel Region of Interest Extraction Layer for Instance Segmentation*" |
|
on COCO object detection. |
|
|
|
## Introduction |
|
|
|
<!-- [ALGORITHM] --> |
|
|
|
This paper is motivated by the need to overcome to the limitations of existing |
|
RoI extractors which select only one (the best) layer from FPN. |
|
|
|
Our intuition is that all the layers of FPN retain useful information. |
|
|
|
Therefore, the proposed layer (called Generic RoI Extractor - **GRoIE**) |
|
introduces non-local building blocks and attention mechanisms to boost the |
|
performance. |
|
|
|
## Results and models |
|
|
|
The results on COCO 2017 minival (5k images) are shown in the below table. |
