# Image Confusion

As you increase the number of degrees of freedom and as you enlarge the zone for an individual degree of freedom, you increase the number of potential matches in a run-time image.

The following figure shows one effect of enabling a degree of freedom on the confusion of the image. With the scale degree of freedom disabled, only a single instance is found. With scale enabled, the top of the pattern is a fair match for a scaled instance of the entire pattern.

In general, the larger the run-time space, both in terms of the size of the zone and in terms of the number of enabled degrees of freedom, the greater the potential for image confusion.
