    This study introduces a novel Text-CNN model for scene text detection, improving accuracy by focusing on text regions and using multi-level supervision. The new system enhances robustness against complex backgrounds, achieving state-of-the-art results.

    Area of Science:

    • Computer Vision
    • Machine Learning
    • Artificial Intelligence

    Background:

    • Deep learning models struggle with scene text detection due to background clutter dominating text features.
    • Existing methods lack discriminative power and robustness in complex image environments.

    Purpose of the Study:

    • To develop a novel text-attentional convolutional neural network (Text-CNN) for improved scene text detection.
    • To enhance the extraction of text-related regions and features, overcoming background interference.

    Main Methods:

    • Proposed a novel Text-CNN architecture focusing on text-specific feature extraction.
    • Developed a multi-level learning mechanism using text region masks, character labels, and binary text/non-text information for training.
    • Introduced contrast-enhancement maximally stable extremal regions (MSERs) for improved low-level text detection.
