Checking Image Overlap with Mathematica – Part 3

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 […]

Checking Image Overlap with Mathematica – Part 2

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 […]

Checking Image Overlap with Mathematica

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. […]

Working with Linguistic Data in Mathematica

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 […]

Cloud Computing with Mathematica

Mathematica provides excellent support for cloud computation, and most of the time, it is a very simple and intuitive process. Today, let us look at some examples of cloud deployment. For using Mathematica’s cloud capabilities, you need an appropriate subscription. I use Mathematica Desktop, which comes with some free cloud credits. OK, let us get […]

Computer Vision with Mathematica

Over the past several weeks, I have been discussing many interesting features of Mathematica. As a continuation, today, I would like to show some cool functionality in the domain of computer vision and machine learning. The function ImageIdentify[] tries to identify the object in the given image. According to the documentation, Mathematica knows about more […]

Natural Language Processing in Mathematica

Welcome back. Today I am going to share with you some of the nice capabilities of Mathematica in the area of Natural Language Processing (NLP). Let us start with words. What if we wish to know the various definitions of the word image? Here is the answer. Mathematica gives the various senses of the word and the […]

Geo Computation in Mathematica

Mathematica has many useful features when it comes to Geo Computation. I wanted to check out some of these features for today’s post. I travel between Chennai and Bengaluru on official work. So, let us start by determining the on-road distance between these cities. It turns out that this is the distance when you travel […]

CUDA and Mathematica

Recently I purchased a high-end desktop computer for my image processing project. Since many computations tend to take several hours to execute, I wanted to accelerate the calculations to the extent possible by adding a GPU. I chose NIVIDA’s GeForce GTX 1080 processor-based card. Although I will be using C++ for my work, because Mathematica 11 […]

Using Julia to Interact with Mathematica

Mathematica is a powerful environment for symbolic and numerical computation. I have been using it for many years now. In this post I had explained how we can use Mathematica bundled with Raspberry distribution to control littleBits devices. When I saw that there is support in Julia for interacting with Mathematica, I decided to investigate it […]
