Today, I was looking for some screenshots I wanted to use for a presentation, and rather than looking through all 1478 of my uploaded camera photos ( ls -1 ~/Dropbox/Camera\ Uploads/ | wc -l ), I decided to write a quick bash script to use the tesseract OCR tool to help me out.

I wanted to use https://github.com/jbochi/python-tesseract so first I installed the dependencies.

sudo pip install PIL
brew install tesseract
cd ~/Dropbox/git/
git clone [email protected]:jbochi/python-tesseract.git
~/Dropbox/git/python-tesseract/tesseract.py ~/Dropbox/Camera\ Uploads/2013-06-06\ 21.55.03.png 
chmod 700 ~/Desktop/find-images-with-text.sh

g = period growth rate, eg, % MOM growth
S = starting size
E = ending size
n = number of periods elapsed between S and E

We know that to compute E from S, g, and n, we can use the equation:

E = S * (1 + g) ^ n

var words = document.body.innerText.trim().replace(/\s+/gi, ' ').split(' ').length;
var avgwpm = 275;  /* 275 words per min avg adult read speed */
console.log(words.toString() + " words / " + Math.round(words/avgwpm).toString() + " min read");
