Improve matching performance from 0.78 to 0.95 using Gauss and gray images, and to 0.98 using blur with 7x7 kernel. I propose using the Gauss 5x5 one, is a bit lower matching ration for the test image, but is better for full different images: if I use blur w/ 7x7 kernel, different images become more similar faster, and that is bad for checkneedle().
