Ontonix Develops Rotation-Invariant Image Complexity Analysis

The analysis of image complexity has been around for over a decade, and numerous examples are available in the present blog. An image is an N x M matrix of pixels and is easy to analyze with, for example, OntoNet, the QCM engine from Ontonix. The first step is to transform an image to greyscale and then to determine the intensity of each pixel on scale ranging, for example, from 0 to 255.

There is a problem, however. If the image is rotated, even slightly, the result changes. Imagine, for example, that we are dealing with MRI images and suppose that two different images, taken at different times, are available, such as the ones below.

If the goal is to identify small local changes, or even large overall differences, this will surely pose a problem. While image complexity is invariant to translations, this is certainly not the case for rotations.

To obviate the problem, a new technique has been developed, which is based on specific mathematical transformations of the original image. The computational requirements are evidently higher than in the traditional approach. The new approach works for all sorts of images, including satellite imagery, infrared, etc.

The new Image Complexity Analysis is available only as a service.

Established originally in 2005 in the USA, Ontonix is a technology company headquartered in Como, Italy. The unusual technology and solutions developed by Ontonix focus on countering what most threatens safety, advanced products, critical infrastructures, or IT network security - the rapid growth of complexity. In 2007 the company received recognition by being selected as Gartner's Cool Vendor. What makes Ontonix different from all those companies and research centers who claim to manage complexity is that we have a complexity metric. This means that we MEASURE complexity. We detect anomalies in complex defense systems without using Machine Learning for one very good reason: our clients don’t have the luxury of multiple examples of failures necessary to teach software to recognize them. We identify anomalies without having seen them before. Sometimes, you must get it right the first and only time!
