1.9. Image Processing Configuration

These instructions provide a more detailed look at the Symphony Profiler Image Processing configuration settings, all of which are available by navigating to Edit > Preferences in the Symphony Profiler Processor.

The Symphony Profiler Processor can identify and remove blank pages from your scanned documents.   Many scanners already have this capability, in which case we recommend that you let the scanner do the work of removing blank pages.   If you have a scanner that does not do this, and you are going to be scanning double sided, here is how to configure the Processor to remove pages:

• Leave "Threshold" at the default

Tip: This threshold defines how sensitive the blank page detection algorithm is.   The higher the number, the less sensitive it is.   The default value should be fine for most cases, but if the scanner is dirty, or you are seeing some 'bleed through' of content from the front side, you may need to increase this number.   At this point, we recommend you provide Trumpet with a document containing any blank pages that were not correctly identified, and we will analyze it and provide a recommended threshold level.

• Leave Required block count set at the default

Tip: The block count also defines how sensitive the blank page detection algorithm is.   The lower the block count, the more sensitive the processor will be to remove blank pages.   For example, if the Required Block Count is set to 1 Symphony Profiler is more likely to treat a page as non-blank than if the Required Block Count is set to 8.     At this point, we recommend you provide Trumpet with a document containing any blank pages that were not correctly identified, and we will analyze it and provide a recommended Block Count.

• Determine what Symphony Profiler should do with blank pages

• Leave blank pages alone:   If a file contains blank pages (e.g. when scanning duplex), all blank pages in the document will remain.   This is the default setting, and is recommended unless the scanner does not provide blank page removal
• Remove blank page following cover:   Symphony Profiler will remove blank pages only following the cover page when scanning duplex
• Remove all blank pages:   This will remove all blank pages including the one immediately after the cover and any others that are blank
