imgutils.detect.text

Overview:

Detect text in images.

Models are hosted on deepghs/text_detection.

../../_images/text_detect_demo.plot.py.svg

This is an overall benchmark of all the text detect models:

Warning

This module has been deprecated and will be removed in the future.

It is recommended to migrate to the imgutils.ocr.detect_text_with_ocr() function as soon as possible. This function uses a higher-quality text detection model provided by PaddleOCR, resulting in improved performance and higher efficiency.

detect_text

imgutils.detect.text.detect_text(image: str | PathLike | bytes | bytearray | BinaryIO | Image, model: str = 'dbnetpp_resnet50_fpnc_1200e_icdar2015', threshold: float = 0.05, max_area_size: int | None = 640)[source]

Detect text regions in the given image using the specified model and threshold.

Parameters:

  • image (ImageTyping) – Input image.

  • model (str) – Model name for DBNET or DBNET++.

  • threshold (float) – Confidence threshold for text detection.

  • max_area_size (Optional[int]) – Max area size when doing inference. Default is 640, which means if the image’s area is over 640x640, it will be resized. When assigned to None, it means do not resize in any case.

Returns:

List of detected text bounding boxes, labels, and scores.

Return type:

List[Tuple[Tuple[int, int, int, int], str, float]]

Warning

This function is deprecated, and it will be removed from imgutils in the future. Please migrate to imgutils.ocr.detect_text_with_ocr() as soon as possible.

Deprecated since version 0.2.10: Use the new function imgutils.ocr.detect_text_with_ocr() instead
