Summary
On the OpenCV 5 (5.x) branch, TextDetectorCNN.Create(modelArch, modelWeights) fails. The class still exists, but OpenCV 5's DNN module removed the Caffe importer:
OpenCvSharp.OpenCVException : Caffe importer has been removed. Please use ONNX-converted models or use an older OpenCV version.
TextDetectorCNN (textboxes) shipped Caffe .prototxt + .caffemodel weights, which can no longer be loaded.
Affected tests
Text.TextDetectorTest.CreateText.TextDetectorTest.Detect
Workaround
Both tests are marked Skip on 5.x.
TODO
- Decide the OpenCV 5 story for
TextDetectorCNN: provide an ONNX-converted model, or deprecate/remove the wrapper.
- Re-enable or remove the tests accordingly.
