Wine & Cheese visited again

A while back we talked about the jpeg artifacts in an image give to me by my good friend Justin Lau. Apparently, my solution did not please him very much. So, I am revisiting the poster again. Here is the output I got with my new algorithm. I will revisit the algorithm again as I know Justin's objections in advance.

The code that generated the following output is up for auction. (Minimum bid is $2500)

Meanwhile, I will keep thinking about how to approach the quality of the poster obtained in pdf format.

Output of my new algorithm that corrects jpeg artifacts

Compare the above result to the original image below ...

The original image with severe jpeg artifacts.

Holiday wine & cheese event is fun

Today, my dear friend Justin Lau, showed me a jpeg poster that he complained was not very good.Of course ! It produces strange artifacts. Below is the poster he showed me:

Original poster

Here is the detail of the artifact:

So, I asked him if I could try to correct the image. And this is what I got with the parameters: 0.01, 6 and 8 in my new algorithm, which is also for auction ($1000 minimum bid).

Complete poster corrected ... sort of see this post also!
