I would like to use lines in captured photos to detect and correct image skew. How would I do this in Go? Most of the packages I've seen on github don't seem to support edge detection or some way to figure out a contiguous line or perhaps a couple markers like QR codes use.

Currently I started working on a personal project where you will constantly receive images, similar or not. Every new image received do I need to loop through absolutely every other image already saved to compare ssim?
The answer is No you can't recover the image from SSIM and Yes you'd have to loop over all images for comparison.
However you may look at image compression to have faster evaluation of the SSIM.
Some example images would be welcome for a better answer.

Now I am struggling in rendering point cloud in WebGL. Once the file size get larger than 200 MB, the browser will crash. I am now using Points in Three.js to render my data.
Is there any way to optimise it or good library I can use to do this case?
This is very broad topic where you can do many ridiculous optimizations.

I want to store user's current location when they log in and display only those users on map which are at a particular distance away from current_user(say 20km).
Popular ruby Geocoder gem has similar functionality. Please checkout the Ryan's screencast for detail.

Recently I came across a online tool, which given a summation calculates its formula. I have tried for many such summations and has given me correct answer.
I was curious as to which algorithm does it use to solve it.
EDIT: It turns out the tool uses wolframaplha api's. But even if you search on wolfram alpha you will get the same result.

I wonder how it is possible to make a visual presentation of algorithm.
I found a very good visualization in Wikipedia like following:
If you know how to make a similar presentation, please let me know.
There are lots of libraries in various languages that can be used to visualize whatever you want, but according to this page:

The picture you're looking at was:
Created with: Ruby 1.8.4, RMagick.
