Sorry. I'm afraid I don't understand.

What is an "algorithm OOP"?

I'm not sure how the previous post relates to the most recent one. You have blurred QR codes and you want to read them? This sounds like a new problem that isn't related to your previous post.

There are many missing details. Is the blurring uniform? What is the source of the blurring? Have you tried a simple thresholding or other image binarization method? If the Binarize function doesn't work, then this requires much more detail to solve.

The answers to these questions really depend on a lot of context. What do you mean by AutoEnhancing? There's a lot of things that could mean. You're probably not going to beat the speed of HistogramTransform. Maybe if you have a batch of photos you can use the same histogram transform over and over on different images and use out of core image processing functions such as ImageFileApply to apply the transformation. That might be quicker with large or a batch of large images.

A simple and dirty way I've found circles involves using MorphologicalComponents to segment the image into subimages with just a single circle in them. Average the values of the circle's pixels to find the center. Average the distance from the center to each circle pixel to find the cirlce's radius. This works okay for simple applications.
