Struct opencv::text::OCRHMMDecoder_ClassifierCallback
source · pub struct OCRHMMDecoder_ClassifierCallback { /* private fields */ }
Expand description
Callback with the character classifier is made a class.
This way it hides the feature extractor and the classifier itself, so developers can write their own OCR code.
The default character classifier and feature extractor can be loaded using the utility function loadOCRHMMClassifierNM and KNN model provided in https://github.com/opencv/opencv_contrib/blob/master/modules/text/samples/OCRHMM_knn_model_data.xml.gz.

Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance
sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold
. Read more
