Finding character bounding boxes

Aspose.OCR for Python via .NET can perform character-by-character recognition and automatically detect bounding boxes of each recognized character using recognize_characters() method.

The method returns a list of CharacterRecognitionResult objects containing each recognized character along with its coordinates in each image.

Property	Description
characters	A list of recognized characters and their coordinates (top-left corner, width and height).
image_index	Sequence number of the image on the page. When working with single-page images, this value is always 0.
page	Page number. When working with single-page images, this value is always 0.
source	The full path or URL of the source file. If the file is provided as a stream, an array of pixels, or a Base64 string, this value will be empty.

Example

The following code example shows how to detect characters in an image:

# Instantiate Aspose.OCR API
api = AsposeOcr()
# Add image to the recognition batch
input = OcrInput(InputType.SINGLE_IMAGE)
input.add("source.png")
# Detect words
results = api.recognize_characters(source, DetectAreasMode.COMBINE)
for c in results[0].characters:
    print("Found character " + c.Value + " by coordinates: left - " + c.Coordinates.X + " |  top - " + c.Coordinates.Y + " | width - " + c.Coordinates.Width + " | height - " + c.Coordinates.Height)
