The raster images in the top row appears more faded and coarse for each instance
further to the right.
The first image (left most) must be smooth and clear
The second image (second from the left) must contain the same colours as
the first image but have course outlining around the objects.
The third image (second from the right) must contain colour that is very faded
but have course outlining around the faded objects.
The last image (right most) must be completed faded such that all the colour
in the first image appears to have gone to white. Some course outlining should
appear in the image.
The top row has no checkerboard pattern visible where the filtered results are.
The rectangle with a green gradient going from left to right appears
more faded for each instance further to the right.
The first image (left most) must be a rect filled with a linear gradient that
transitions from solid green to transparent green.
The second image (second from the left) must be identical to the first image.
The third image (second from the right) must contain a linear gradient that transitions
from a solid faded green to transparent faded green.
The last image (right most) must contain a linear gradient that transitions from
solid white to transparent white.
The bottom row must show 95% of the checkerboard pattern where the filtered results are
since the gradients are transparent.
