Can't analyse layout. Make sure 'osd.traineddata' available in 'tessdata'. Empty page!! Empty page!!

Could you provide your code and any tesseract output, if exists, so we could investigate this issue deeply?

Have you seen the tessedit_pageseg_mode (kG8ParamTesseditPagesegMode) parameter? https://github.com/gali8/Tesseract-OCR-iOS/blob/master/TesseractOCR/G8TesseractParameters.m http://www.sk-spell.sk.cx/tesseract-ocr-parameters-in-302-version

I use the demo project，Not output. Or set some parameters?

I meant console output of tesseract.

Hi,

I get the same error (Can't analyse layout. Make sure 'osd.traineddata' available in 'tessdata'.) when i try to set PageSegmentationMode to PageSegmentationModeAuto, any help?

I already download that file here (https://github.com/tesseract-ocr/tessdata/blob/master/osd.traineddata) and put in into the tessdata folder, but no success.

@Jan-M-B which language are you trying to use? Can you post your code?

I have same error. My code

    G8RecognitionOperation *operation = [[G8RecognitionOperation alloc] initWithLanguage:@"nep"];
    operation.tesseract.engineMode = G8OCREngineModeTesseractOnly;
    operation.tesseract.pageSegmentationMode = G8PageSegmentationModeAuto;

    operation.delegate = (id)self;
    operation.tesseract.image = bwImage;
    [operationQueue addOperation:operation];

    operation.recognitionCompleteBlock = ^(G8Tesseract *tesseract) {
        // Fetch the recognized text
        NSString *recognizedText = tesseract.recognizedText;

     };

Can help me.
