Image Processing

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 […]

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. […]
