How to increase the font size of the bounding box in Tensorflow object detection module?

Find "visualization_utils.py"
This exist in "research/object_detection/utils"
And find below code, modify font size.
If it is not working, change path to absolute path.
Or copy font file to project folder.

Thank you.
try:
#font = ImageFont.truetype('arial.ttf', 24)
font = ImageFont.truetype('/Library/Fonts/Arial.ttf', 100) #leon modify
except IOError:
font = ImageFont.load_default()


Font size up

Thank you.



 


Image data : background images

This is background images those are 12,439.
I used this images for negative data when I train face detection model.

This is random images and there is no specific object.
So it will be use for background image or negative image.

google object detection api error: ModuleNotFoundError: No module named 'pycocotools’

You might see this error : No module named 'pycocotools’, when you try to start train.
I refer to my solution.
Good luck!

Error:
ModuleNotFoundError: No module named 'pycocotools’

Solution :
git clone https://github.com/cocodataset/cocoapi.git
cd cocoapi/PythonAPI
make

cp -r pycocotools <path_to_object_detection_api>/models/research/


google object detection api error : object_detection/protos/model.proto:12:5: "Ssd" is not defined.

You might meet this error : "object_detection/protos/model.proto:12:5: "Ssd" is not defined.", when you try below command.

# From tensorflow/models/research/
protoc object_detection/protos/*.proto --python_out=.


I solved this error to use below work.

# Make sure you grab the latest version
curl -OL https://github.com/google/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip
