This is done using RMagick's quantize method. In fact, that's the first thing we want to do because Tesseract works best with black-and-white images. RMagick is a library for Ruby that allows us do a variety of graphics operations in our program, such as changing an image's color.
tif files for every page in the original PDF. You should see a file called data.swf with a size of more than 1MB.Ĭlick the printer icon, circled in red, and print the file as a PDF.
Visit the Lilly faculty registry and observe your browser's traffic through Firebug (see my previous tutorial). This can be done (though not as easily) with Adobe Acrobat Pro.

We came up a way to download the file and programmatically to extract tabular data from it. However, when we began work on Dollars for Docs, Lilly was only providing data in the FlashPaper format. In any event, Lilly now provides their data as a PDF, with copyable text. Scott MacGregor called the characterization "misleading, as it was never our intention to make it difficult for people to access information" and said that preserving integrity of the data was the reason for not making it downloadable initially. PharmaShine, a company that maintains a commercial database of physician payments, said it had to manually retype the entire list.Įli Lilly disagrees with the Times' story's characterization that it had "purposely made its report impossible to download." In an e-mail to ProPublica, Lilly spokesman J. However, Lilly was criticized in an April 2010 New York Times article for using a proprietary and discontinued format - Adobe's "FlashPaper" - which made the data virtually impossible to download or copy.

Reassemble these (hundreds of) text files in the same order that you divided the main image, creating a (text) spreadsheet of the data.Ī caveat: The code examples provided here are specific to the FlashPaper version of Eli Lilly's doctor payment disclosures, such as the black outlines of its table cells.Įli Lilly became the first major drug company to post its physician payments online in July 2009. Perform optical character recognition on each cell to translate the image into a textfile.Ĥ. Break the image apart along those lines to create (hundreds of) individual image files, one for each cell.ģ. Determine the positions of the lines that divide the rows and columns on a page.Ģ. In this tutorial, we'll explain how to write a program to extract the data into tabular format.
When a PDF contains just images of text, as they do in scanned documents, then the problem isn't just how to convert them into neat tabular data, but how to extract any text, period. However, those only handle PDFs that have actual text embedded within them. (,, , ], 'tag', 0.In the previous guide, we describe several methods for turning PDFs into data usable for spreadsheets.

EasyOCR is created by the company named Jaided AI company. EasyOCR supports 42+ languages for detection purposes. EasyOCR like any other OCR(tesseract of Google or any other) detects the text from images but in my reference, while using it I found that it is the most straightforward way to detect text from images also when high end deep learning library(PyTorch) is supporting it in the backend which makes it accuracy more credible. What is EasyOCR?ĮasyOCR is actually a python package that holds PyTorch as a backend handler. OCR is a technology that enables you to convert different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera into editable and searchable data. OCR is actually a complete process under which the images/documents which are present in a digital world are processed and from the text are being processed out as normal editable text. OCR is formerly known as Optical Character Recognition which is revolutionary for the digital world nowadays. This article was published as a part of the Data Science Blogathon What is OCR?
