Pattern Recognition Demo


Location

$NitroSDK/build/demos/prc

Compilation

Move to the $NitroSDK/build/demos/prc directory and enter:

% make

Executable (.nef, .srl files) will be generated in

$NitroSDK/build/demos/prc/sample_name/bin/platform/target/.

For example:

$NitroSDK/build/demos/prc/characterRecognition-1/bin/ARM9-TEG/Release/

Execution

Navigate to the $NitroSDK/build/demos/prc/sample_name/bin/platform/target/ directory and perform one of the following:

Description

characterRecognition-1 Recognizes input from the touch panel as characters.
This sample program illustrates a procedure for running a time-consuming recognition API in the background with another thread.
characterRecognition-2 Recognizes input from the touch panel as characters.
It is possible to compare various recognition engines and parameters, and confirm recognition results and calculation times.
It also has a simple tool that creates a pattern sample list.

Operation

When using a TEG board, if no touch panel device is attached characterRecognition-1, characterRecognition-2 will not function properly.

characterRecognition-1, characterRecognition-2 attempt to read touch panel calibration values from the non-volatile memory (NVRAM) in the retail product. If they cannot properly read, they will terminate in error. In this case, use the boot menu in the retail product or BootMenu.srl to store calibration results in NVRAM.

When using characterRecognition-2 as a simple tool for creating pattern sample lists, refer to the demo tool pdic2c.pl.
