TextTron is a simple light-weight image processing based text detector in document images.
Project description
TextTron-Lightweight-text-detector
1. Introduction
TextTron is a simple light-weight image processing based text detector in document images. TextTron detect text with the help of Contours applied on a preprossed image. This meant for fast text detection without using any machine learning or deep learning model. Though this will not work well in scene text detection, only meant for document images
2. Quick Start
1. Requirements: numpy & opencv-python
pip install numpy
pip install opencv-python
2. Install the package
$pip install TextTron
Code is developed under following library dependencies
OpenCV = 4.1.2
NumPy = 1.17
3. Usage
3.1 API
i. Import the neccessary libraries and read the image
import cv2
from TextTron import TextTron
img = cv2.imread(PATH)
ii. Pass the numpy or cv2 image to the TextTron
TT = TextTron(img)
TT = TextTron(img, low=196,high=255,yThreshold=15,xThreshold=2) # Change this till you get good result
iii. Get the text bounding boxes
tbbox = TT.textBBox
iv. Get the ploted image (optional)
plotImg = TT.plotImg
v. If you want to set/decide best parameter for your case (optional)
TextTron.setParameters(img)
