Merge Text Boxes
[简体中文](./docs/README_zh.md) | English
### Introduction
This repo is mainly used to merge peer text boxes. The code is modified from the [merge_text_boxs](https://github.com/zcswdt/merge_text_boxs) project and further organized and expanded.
### Installation
```bash
pip install merge_text_boxes
```
### Usage
```python
import copy
import cv2
import numpy as np
from merge_text_boxes import MergeTextBoxes
rects = [
[144, 5, 192, 25],
[25, 6, 64, 25],
[66, 6, 141, 25],
[193, 5, 275, 33],
[269, 30, 354, 50],
[26, 30, 182, 52],
[185, 28, 265, 55],
[25, 56, 89, 76],
[93, 56, 229, 78],
[232, 56, 262, 76],
[264, 52, 343, 81],
]
show_image = np.zeros([100, 500, 3], np.uint8) + 255
connector = MergeTextBoxes(max_dist=15, overlap_threshold=0.2)
new_rects = connector(rects, 500)
tmp_img = copy.deepcopy(show_image)
for rect in rects:
cv2.rectangle(tmp_img, (rect[0], rect[1]), (rect[2], rect[3]), (0, 0, 255), 1)
cv2.imwrite("origin.png", tmp_img)
for rect in new_rects:
cv2.rectangle(show_image, (rect[0], rect[1]), (rect[2], rect[3]), (255, 0, 0), 1)
cv2.imwrite("res.png", show_image)
```
