- 1: Search the scanned image in groups of 2 pixels.
- 2: Search the scanned image in groups of 4 pixels.
- 3: Search the scanned image in groups of 8 pixels.
- To increase the speed of your search, you must take into account the settings listed below.
1. When using the high precision setting, a smaller image should be used.
2. Reduce the size of the scanned image.
3. After considering what the maximum out of position dimension would be, make the
search area as small as possible.
4. If the size of the object is larger than 8 pixels then set the pixel contraction to "3".
