We show that in creating the projection matrix we need not necessarily use the actual image, but can use some perturbed version of it to move the solution in the direction we desire. In this example we show how we can increase the sharpness of the resulting digital zoom operator by adding a small amount of a Sobel operator to the original training image. This leaves the possibility of applying various operators to the training image to produce a solution closer toward our desired solution. Our example is again done for a 5X zoom with blur.
