How to Handle PDF in Python

We all must be familiar with PDFs. In fact, they are one of the most important and widely used digital
media. PDF stands for Portable Document Format. It uses .pdf extension.
Why Python for PDF processing?
As you know PDF processing comes under text analytics. Most of the Text Analytics libraries or frameworks are
designed in Python only. This gives leverage to text analytics. One more
thing you can never process a pdf directly in existing frameworks of Machine
Learning or Natural Language Processing. Unless they are proving an explicit
interface for this, we have to convert pdf to text first.
So, in this article I will
take you through some of the basic process of pdf in python.
Python
can also read PDF files and print out the content after extracting the text
from it.
For
that we have to first install the required module which is PyPDF2. Below is the
command to install the module. You should have pip already installed in your
python environment.
pip install pypdf2
When it successfully gets
installed, we can read PDF files using the methods available in the module.
import PyPDF2
pdfName = 'path\InsideAlMl.pdf'
read_pdf = PyPDF2.PdfFileReader(pdfName)
page = read_pdf.getPage(0)
page_content = page.extractText()
print page_contentWhen
we run the above program, we get the following output −
How to Do Face Animation Using Ai(Mo-Cap, for short) is
the process of recording with camera real-life movements of people for the
purpose of recreating those exact movements in a computer-generated scene. As
someone who is fascinated by the use of this tech in game development for
creating animations, I was thrilled to see the massive improvements brought to
this tech with the help of Deep Learning.
In this article, I want
to share a quick overview of the recently published NeurIPS paper “First Order Motion Model for Image Animation” by A. Siarohin et. al. and demonstrate how its
application to the Game Animation Industry will be “game-changing”.
Reading Multiple Pages
To
read a pdf with multiple pages and print each of the pages with a page number we
use the loop with getPageNumber() function. In the below example we the PDF
file which has two pages. The contents are printed under two separate page
headings.
import PyPDF2
pdfName = 'Path\Tutorialspoint2.pdf'
read_pdf = PyPDF2.PdfFileReader(pdfName)
for i in xrange(read_pdf.getNumPages()):
page = read_pdf.getPage(i)
print 'Page No - ' +
str(1+read_pdf.getPageNumber(page))
page_content = page.extractText()
print page_contentWhen
we run the above program, we get the following output −
Page No - 1
MotionScan
Technology
It was way back in 2011
when the game L.A. Noire came out with absolutely amazing life-like
facial animations that seemed so ahead of every other game. Now, almost a
decade later, we still haven’t seen many other games come anywhere close to matching
its level in terms of delivering realistic facial expressions.

PDF: https://arxiv.org/pdf/2003.00196.pdf
In this research work,
the authors present a Deep Learning Framework to create animations from a
source image of a face, by following the motion of another face in a driving
video, similar to the MotionScan technology. They propose a self-supervised a training method that can use unlabeled data-set of videos of a particular
category to learn the important dynamics that define motion. Then, then show
how these motion dynamics can be combined with a static image to generate a
motion video.
I hope after you enjoyed reading this article and finally,
you came to know about How to Handle PDF in Python.
