Faster interpretation of the original COCOEval
Project description
Faster-COCO-Eval
Disclaimer
I often use this project, but I saw it abandoned and without a public repository on github. Also, part of the project remained unfinished for a long time. I implemented some of the author's ideas and decided to make the results publicly available.
Faster-COCO-Eval base
This package wraps a facebook C++ implementation of COCO-eval operations found in the pycocotools package. This implementation greatly speeds up the evaluation time for coco's AP metrics, especially when dealing with a high number of instances in an image.
Comparison
For our use case with a test dataset of 5000 images from the coco val dataset. Testing was carried out using the mmdetection framework and the eval_metric.py script. The indicators are presented below.
Visualization of testing comparison.ipynb available in directory examples/comparison Tested with yolo3 model (bbox eval) and yoloact model (segm eval)
Type | COCOeval | COCOeval_faster | Profit |
---|---|---|---|
bbox | 18.477 sec. | 7.345 sec. | 2.5x faster |
segm | 29.819 sec. | 15.840 sec. | 2x faster |
Usage
This package contains a faster implementation of the
pycocotools COCOEval
class.
To import and use COCOeval_faster
type:
from faster_coco_eval import COCO, COCOeval_faster
....
For usage, look at the original COCOEval
class documentation.
Usage plot curves
from faster_coco_eval import COCO
from faster_coco_eval.extra import Curves
cocoGt = COCO(....)
cocoDt = cocoGt.loadRes(....)
cur = Curves(cocoGt, cocoDt, iou_tresh=0.5, iouType='segm')
cur.plot_pre_rec(plotly_backend=False)
Setup dependencies
- numpy
- plotly (optional if extra.Curve usage)
