Interesting article about the pixel and it's origins, and how the inventor of pixels wishes that he hadn't created them square.
Now 50 years later, he's making amends by working on a new algorithm using variable sized pixels and applying them to imaging technology.

Quote:Kirschâs method assesses a square-pixel picture with masks that are 6 by 6 pixels each and looks for the best way to divide this larger pixel cleanly into two areas of the greatest contrast. The program tries two different masks over each area â in one, a seam divides the mask into two rough triangles, and in the other a seam creates two rough rectangles. Each mask is then rotated until the program finds the configuration that splits the 6-by-6 area into sections that contrast the most. Then, similar pixels on either side of the seam are fused.
