Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
The valuation represents a 31% increase from the $6.1 billion valuation the 13-year-old company achieved in April of last year, when it raised a $575 million round led by Franklin Templeton for partly the same purpose: purchasing shares from employees, including to help them cover the taxes associated with converting expiring restricted stock units (RSUs, a form of equity compensation) into shares.
