# Mathematica

Mathematica 12 was released a few days ago.  It has been over a year since version 11.3 came out in March 2018. The long wait appears justified since the new release boasts of numerous improvements and new features across several areas. You may want to read this blog post by Stephen Wolfram. In the area of […]

About 10 days ago, I received an update for Mathematica. The latest version is 11.3.0. As usual, I looked through the list of new features in this release. There are several new features, but one of them attracted my attention immediately: There is a new function FindTextualAnswer that, given a piece of text and a question, can […]

In the previous post I showed how we can use Mathematica to analyse screenplays, and gave some interesting statistics about the various characters and scenes from the movie The Prestige. In today’s post, I want to continue that discussion by sharing some more statistics, and then look at another movie, The Bourne Ultimatum. We concluded […]

I have a close relative who is an aspiring movie screenplay writer. During one of our recent meetings, he shared with me with a lot of interesting information about screenplay writing and its challenges. He even lent me a few good books to read further. One of the books is Essentials of Screenwriting by Richard […]

This is the  third and the last in the series of articles on checking image overlap using Mathematica. Let us take a quick look at the images that we are using as samples (image1 and image3 in the first row, image3 and image4 in the second row): The first technique we will consider today is […]

In the previous post, we discussed one technique to check the overlap between two given images of equal dimensions. In today’s post, let us look at another idea that uses Mathematica’s ImageCorrespondingPoints function. As per the documentation, the ImageCorrespondingPoints function finds a set of matching interest points between two given images and returns their coordinates. Internally […]

Recently I had to solve a seemingly simple problem: Given two images, can we find out if there is any overlap between the two? Where does such a requirement arise? One use case is in photogrammetry, where in order to build an orthomosaic from multiple images, there must be at least 70% overlap between consecutive images. […]

There are many interesting functions in Mathematica for working with language data, not just in English but in many other languages too. The DictionaryLookup[] function is a good starting point. Let us see what languages are supported as part of dictionary lookup: That is a good collection. It is nice to see that our National […]
