Bug

It's wired, when i use easyocr on huggingface or demo site, the result is much better than with docling. Do not understand what happened, but i am trying debug code and also want to know the answer from developers?

Reproduce

Here is my code

from docling.backend.pypdfium2_backend import PyPdfiumDocumentBackend
from docling.datamodel.base_models import InputFormat
from docling.datamodel.pipeline_options import PdfPipelineOptions
from docling.document_converter import DocumentConverter, PdfFormatOption

pipeline_options = PdfPipelineOptions()
pipeline_options.do_ocr = True
pipeline_options.do_table_structure = True
pipeline_options.ocr_options.use_gpu = False
pipeline_options.table_structure_options.do_cell_matching = True
pipeline_options.ocr_options.lang=["vi"]

doc_converter = DocumentConverter(
    format_options={
        InputFormat.PDF: PdfFormatOption(
            pipeline_options=pipeline_options, backend=PyPdfiumDocumentBackend
        ),
        InputFormat.IMAGE: PdfFormatOption(
            pipeline_options=pipeline_options, backend=PyPdfiumDocumentBackend
        )
    }
)

test2 = doc_converter.convert("/home/jonas/Pictures/Screenshots/1.png")
print(test2.document.export_to_dict())
