Testing Processes

Once you have configured processes and image enhancements, you can test them on a sample image before scanning large numbers of documents. For best results when testing processes, add a custom sample image that represents a typical document you will be scanning for the document class. Once a process is configured, you will have the option to Test Processes or Test Current Process.

• Test Processes will test all the processes in the tree up to the process you have selected. The results will be displayed on the sample image or Text Pane and in the Processing Information Pane. You can adjust or add processes and enhancements until you are satisfied with the results.
• Test Current Process tests only the currently selected process. The results will be displayed on the sample image or Text Pane and in the Processing Information Pane. You can adjust the settings for that process and test until you are satisfied with the results.

You can use Test Processes and Test Current Process alternately to view and adjust the results of the processes you are configuring.

Example: Buster wants to perform Optical Character Recognition (OCR) on documents during processing. He configures OmniPage OCR in Page Processing and a representative sample image for the document class. He clicks Test Current Process and opens the Text Pane to see the results. He discovers that the results contain some errors. He notices that there are some extra speckles on the scanned document that may be interfering with the character recognition, so he decides to use the Despeckle image enhancement to remove them. He configures Despeckle and clicks Test Current Process to see the results on the sample image. It seems to have removed most of the speckles, so he selects OmniPage OCR in the Session Configuration Pane and selects Test Processes. Because Despeckle is configured before OmniPage OCR, this will test the effects of Despeckle on OmniPage OCR. Buster notices that the Despeckle has removed some segments of characters, such as periods and the dots on the letter i. He selects Despeckle in the Configuration Pane and in the Tasks Pane adjusts its properties so it removes only smaller speckles. He selects OmniPage OCR in the Configuration Pane again and clicks Test Processes. Now the OmniPage OCR is accurate, and Buster feels confident that the session is configured correctly to meet his goals.
