Class DocumentQualityAnalyzerConfiguration

Enable orientation detection. Document orientation will be returned in DocumentQualityAnalyzerResult.orientation.

Default Value

false;
Copy

Inspect small text (typically less than 12 pixels height) when analyzing the document quality. If true, processing will be slower, but when the quality issue with a document is the low resolution of the text, then the issue will be caught.

Default Value

false;
Copy

Maximum image size in pixels, if image is bigger, it will be resized.

Default Value

2000;
Copy

At most this fraction of the image will be processed, range is from 0 to 1. Decreasing this value below 1.0 can lead to faster processing but may result in less accurate prediction, as only a subset of the image tiles will be analyzed.

Default Value

1.0;
Copy

If estimated number of symbols is less than this value, return that document is not found.

Default Value

20;
Copy

If this number of symbols is found and minProcessedFraction of the image is processed, the processing stops.

Default Value

100;
Copy

At least this fraction of the image will be processed, range is from 0 to 1. Decreasing this value below 1.0 can lead to faster processing but may result in less accurate prediction, as only a subset of the image tiles will be analyzed.

Default Value

1.0;
Copy

If detectOrientation is True, minNumberOfRequiredSymbols is found, and orientationConfidence is bigger than this threshold, the processing stops. If the maxProcessedFraction part of the image is processed and orientationConfidence is lower than the threshold, the returned orientation will be 0.

Default Value

0.0;
Copy

quality levels.

Default Value

["VERY_POOR", "POOR", "REASONABLE", "GOOD", "EXCELLENT"];
Copy

Quality thresholds to separate quality levels.

Default Value

[new DocumentQualityThreshold({
    "symbolQuality": 0.5,
    "symbolRatio": 0.5
}), new DocumentQualityThreshold({
    "symbolQuality": 0.7,
    "symbolRatio": 0.3
}), new DocumentQualityThreshold({
    "symbolQuality": 0.85,
    "symbolRatio": 0.3
}), new DocumentQualityThreshold({
    "symbolQuality": 0.9,
    "symbolRatio": 0.1
})];
Copy

If true, will return the quality heatmap as a part of the result. In this case, the entire image will be processed and the minProcessedFraction will be ignored. Useful for debugging situations where the returned quality doesn't appear to match the perceived quality.

Default Value

false;
Copy

Image will be processed in tiles of this size; will be ignored if image is small.

Default Value

300;
