Visualizing Yolov5's layers using GradCam

Overview

YOLO-V5 GRADCAM

I constantly desired to know to which part of an object the object-detection models pay more attention. So I searched for it, but I didn't find any for Yolov5. Here is my implementation of Grad-cam for YOLO-v5. To load the model I used the yolov5's main codes, and for computing GradCam I used the codes from the gradcam_plus_plus-pytorch repository. Please follow my GitHub account and star the project if this functionality benefits your research or projects.

Installation

pip install -r requirements.txt

Infer

python main.py --model-path yolov5s.pt --img-path images/cat-dog.jpg --output-dir outputs

NOTE: If you don't have any weights and just want to test, don't change the model-path argument. The yolov5s model will be automatically downloaded thanks to the download function from yolov5.

NOTE: For more input arguments, check out the main.py or run the following command:

python main.py -h

Examples

Open In Colab

cat&dog

cat&dog

cat&dog

Note

I checked the code, but I couldn't find an explanation for why the truck's heatmap does not show anything. Please inform me or create a pull request if you find the reason.

TO Do

  1. Add GradCam++
  2. Add ScoreCam
  3. Add the functionality to the deep_utils library
