Differences from the OCV Tool

The OCVMax tool described in this chapter differs from the OCV tool described in the chapter OCV Tool in the following ways:

Image-based training:

For every character your vision application must verify, the OCV tool requires you to generate a font model sampled from one or more acquired images. The OCVMax tool uses an existing font file to define the model for each character, but the font file can be generated from an image or produced synthetically. If you have the font file for the characters in the strings you want to verify, configuring an OCVMax tool is generally quicker than configuring an OCV tool.

Search reliability:

The OCVMax tool uses PatMax technology to search for each character string, allowing greater reliability in locating each string as its position varies in successive images.

Distortion:

The OCVMax tool can handle far more image-to-image character distortion than the OCV tool.
