Yolov9-textregions-handwritten
A yolov9 instance segmentation model for segmenting text-regions in handwritten running-text documents
Model Details
Model Description
This model was developed for segmenting text-regions in handwritten running-text documents. It is meant to be implemented in an HTR-pipeline where one first segment text-regions, then text-lines within the regions, and then feed these text-lines to an HTR-model.

Uses
Direct Use
Segment text-regions in handwritten running-text documents
Downstream Use [optional]
As part of an HTR-pipeline for transcribing entire pages of handwritten running-text documents. See Swedish Lion Libre for example usage with the HTRflow package
How to Get Started with the Model
How to Load and Use the YOLOv9 Instance Segmentation Model
Below is the Python code to load and use the trained YOLOv9 instance segmentation model using the Ultralytics repo:
import torch
from ultralytics import YOLO
# Load the trained YOLOv9 model
model = YOLO('path/to/your/model.pt') # Update with the correct path to your trained model
# Load an image
img = 'path/to/your/image.jpg' # Update with the path to the image you want to use
# Perform instance segmentation
results = model(img)
# Display results
results.show() # Show image with predicted masks
# To get the raw predictions (bounding boxes, masks, etc.)
for result in results:
print(result.boxes) # Bounding boxes
print(result.masks) # Segmentation masks
Usage with the HTRflow package
See the model card for Swedish Lion Libre for example usage with the HTRflow package, or refer to the documentation for HTRflow

Evaluation

Metrics
Standard metrics for instance segmentation. Note that evaluation of segmentation as part of an HTR-pipeline should be measured by what effect it has on the following HTR, that is, CER and WER. For implementation and evaluation of entire HTR-pipelines, please check out HTRflow, the Swedish National Archive's open-source package for HTR and OCR projects.
