Blurred Test Solves Several Cases

Testing the blurred images again i found a human error in my code due to reusing code from elsewhere in the program. It is now fixed and actually shows a good improvement in that all images are classified as Present if they truly are present. I have yet to see a test/sample case where the images have been incorrectly classified.

Also with the new blurred image code the images are now actually picking up previous blurred images too. Showing that a careful selection of varying conditions from illumination to blurred tests will give results that a usable throughout the system. Ideally a larger set of training data would be used rather than the minimal 12 training images currently working with, yet this gives reasonable results to the minimum degree of accuracy required...100% coverage of all target images, yet still allows through a few similar images that are not truly targets (i.e true negatives).
