Area of Science:

  • Computer Vision
  • Artificial Intelligence
  • Document Analysis

Background:

  • Chinese seal text recognition is crucial for efficient document processing.
  • Low accuracy is attributed to image blurring, occlusion, and limited datasets.
  • Existing methods struggle with these challenges.

Purpose of the Study:

  • To develop robust models for accurate Chinese seal text detection and recognition.
  • To address limitations of existing methods, particularly with small datasets and image degradation.
  • To improve overall efficiency in administrative document workflows.

Main Methods:

  • Improved Differentiable Binarization (DBnet) model (DB-ECA) incorporating efficient channel attention (ECA) and delayed downsampling for text detection.
  • Lightweight Seal Text Recognition (LSTR) model utilizing a lightweight CNN, self-attention, and Connectionist Temporal Classification (CTC) for text recognition.
  • Developed a novel homemade dataset for experimental validation.

    • Main Results:

    • DB-ECA outperformed five common detection models with precision (90.29%), recall (85.17%), and F-measure (87.65%).
    • LSTR achieved the highest accuracy (91.29%) compared to five recent recognition models.
    • LSTR demonstrated advantages in parameter efficiency and inference speed.

    Conclusions:

    • The proposed DB-ECA and LSTR models significantly enhance Chinese seal text recognition accuracy and efficiency.
    • These models offer effective solutions for real-world scenarios with data scarcity and image quality issues.
    • The developed models represent a notable advancement in automated document processing and administrative efficiency.
