I am assuming, finding the colour coordinates of the colour patches would be easy, and so would the random pixel noise of a grey patch representing 50% grey. This is the reason I intend to try Mathematica, which I have no experience with, but willing it to try. I am not very happy with the Siemens star measurements, as they are not consistent with what I measure manually using PhotoShop for example.

As you can see I am also measuring other parameters of the reproduced test chart, like the colour, Gamma and noise.

But I am now attaching the original real export of a CCTV camera (typically they are HD or 4k resolution) and the measurements that I have made using Matlab. I am not sure why you didn't see the original image I had attached in my last response, as I used the 'Add file to the post'. The last response from Henrik seems to be what I am after, and it is very promising. I am also adding an attachment, a simple explanation on how this resolution is measured. Happy to consider even paying somebody for their time if they can do what I have described in my video in the able mentioned URL link. If anybody can help me in either giving me a list of functions to look at, or perhaps somebody would know exactly how to calculate the above mentioned resolution, I would gladly purchase a full licence of Mathematica and investigate this further. I am under impression that Mathematica is much more powerful, but as with anything new, it is hard for me to find a function or algorithm of how I can measure resolution of a Siemens sine-wave star, which I use in my ViDi Labs test charts ( ) and developed a little program using MatLab to find the circles in an image, and then measure resolution (or MTF = Modulation Transfer Function), based on the 10% Depth of Modulation, as described by the IEC 62676-5 standards. I am new to the Wolfram language, and I only used a trial version of the Mathematica to see if there is a way to replace my Siemens sine-wave star measurement for my test chart, using MatLab.
