OCR Using Azure Computer Vision API

I have been getting some good feedback on Azure’s Computer Vision API, in particular, the OCR functionality. Although I am not working on any project that requires this functionality at the moment, I thought it would be a good idea to check out the service – just to be “future ready”! This article is not […]

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. […]
