Sparrow Parse: Table Data Extraction with Table Transformer and OCR

I explain how we extract data with Sparrow Parse, using Table Transformer to identify table area and build table structure to be processed by OCR. Sparrow Parse implements additional logic to clear-up and improve (removing noise, merging columns, adjusting rows) table structure generated by Table Transformer.

 

Table Header Extraction with Table Transformer

Table Transformer model is able to provide table functional analysis. As result we can identify table header area and build cells to enclose each column header. In the next step with crop each cell and read data with OCR. Finally we get structured data for table header column names.
