Image Enhancement

Use these options to improve the quality of imported images by automatically rotating them to the correct orientation, deleting blank pages or performing various image clean-up operations.

Deskew[edit | edit source]

Straightens the page, correcting any skew that might have occurred during scanning.

Despeckle[edit | edit source]

Cleans the image, removing stray pixels and marks. The enhanced despeckle included with the Full version will also remove shaded backgrounds from images.

Erase Black Borders[edit | edit source]

Removes black borders around the edge of the page that some scanners produce. Only works with black and white TIFF images.

Invert Colors[edit | edit source]

Invert the colors of the image, which make it look like photo negative.

Automatic Rotatation[edit | edit source]

Checking this option will cause SimpleIndex to attempt to detect the proper page orientation and rotate the image automatically to this position.

Automatic rotation uses a “best guess” algorithm to determine the page layout. This works very well with text documents, but accuracy decreases the more tables, handwriting, and pictures you have on the page. It should not be expected to work 100% of the time.

Prior to version 10, this option only worked with black and white TIFF images. All image formats are supported for auto-rotate in 10, though the accuracy is best on images with black and white text on them.

Invert Colors[edit | edit source]

Reverse the colors in the image automatically. This will switch Black with White on B&W images, or create a “negative” image for color.

Rotate Odd (Front) Pages[edit | edit source]

Rotates odd pages the selected number of degrees clockwise. Separate values for even and odd pages allow front and back pages to be rotated independently.

Rotate Even (Back) Pages[edit | edit source]

Rotates even pages the selected number of degrees clockwise. Separate values for even and odd pages allow front and back pages to be rotated independently.

Blank Page Detection[edit | edit source]

This section allows for automatically deleting blank pages from the scanned or process image files. This option is good for scanning mixed batches of single and double-sided pages and removing the blanks automatically.

Minimum File Size (Faster)[edit | edit source]

Automatically deletes blank pages by removing any files smaller than the value specified here (in Bytes). A good setting for this value is 10000, but this can be adjusted to meet the specifics of your scanning environment. If pages are getting deleted that should not be then the number should be lowered. If pages are not getting deleted that should be then the number should be raised.

A value for this field is required for the blank page Autonumber and OCR features to work.

Black Pixel Ratio (More Accurate)[edit | edit source]

Automatically deletes blank pages using the ration of color to white pixels. 1 being the highest and 0 being the lowest, with the recommended range being between 0.001 and 0.010.
