# High Sensitivity Mode

PatMax can be run in standard mode or high sensitivity mode. Check your images for contrast and noise. Good quality images should be run in standard mode but if your images have poor contrast or are noisy, you may get better results using high sensitivity mode. Keep in mind however, high sensitivity mode generally requires more execution time than standard mode.

When you use high sensitivity mode you can also set the sensitivity parameter which allows you to specify your image quality. The sensitivity parameter is a number in the range 1.0 through 10.0 where lower numbers specify better quality images and higher numbers specify poor quality images. The default is 2.0. You may need to experiment with this parameter range to see which setting produces the best results for your images. See the discussion in the section High Sensitivity Mode.
