# Search Parameters

The OCVMax tool uses a variety of search parameters to locate the character strings in the images you acquire. The tool uses image search parameters to locate and identify each character string, and character search parameters to locate individual characters within the string.

By enabling the tuning feature, an OCVMax tool can generate good starting values for these search parameters. You can enable, disable, and alter these values as necessary to improve the ability of the tool to locate and verify good character strings, or to reduce the time necessary for the tool to function successfully. See the section OCVMax Optimization for optimization suggestions.
