Default Parameters

The default 'Image - Clean Up (Document)' flow action parameters are detailed below:

• Filename: The filename of the source PDF document (including the file extension)
• File Content: A Base64 encoded representation of the PDF document
• Clean Operations: Configures which 'Clean Operations' should be executed.

By default, the 'Clean Operations' setting is set to 'Default', which will apply the following clean-up operations:

• Deskew - Detects the skew angle and rotates to remove that skew
• Despeckle - Automatically detects speckles and removes them
• Auto Rotate - Automatically detects orientation and rotates so that the text is upright oriented

Advanced Parameters

The advanced 'Image - Clean Up (Document)' flow action parameters are detailed below:

NOTE: These settings will only apply when the 'Clean Operations' value is set to ''Specific"

• Auto Rotate - Automatically detects orientation and rotates so that the text is upright oriented
• Deskew - Detects the skew angle and rotates to remove that skew.
• Despeckle - Automatically detects speckles and removes them.
• Adjust Brightness and Contrast - This action analyzes an image and automatically adjusts brightness and contrast based on the analysis.
• Remove Border - Locates border pixels and removes the pixels from the image.
• Smooth Background - This works only on color and grayscale images. This operation smoothes background colors to eliminate or de-emphasize noise.
• Smooth Objects - This only works on bitonal images; it looks at groups of pixels, finds isolated bumps and pits in the edges of those objects, and fills them in.
• Remove Dot Shading - This action will remove shaded regions from bitonal images.
• Image Detergent - Image Detergent works by changing pixels of similar color values to a central color value, which has the result of smoothing the image wherever regions of those colors appear.
• Average Filter - Performs a 3x3 Average filter smoothing operation on the image, placing the output in the center of the window.
• Remove Hole Punch - Detects and removes hole punch marks from a bi-tonal image.
• Binarize - Computes all necessary parameters by analyzing the input data before actually performing the binarization. The algorithm is tuned to typical document images, consisting of dark text on a brighter background. It is robust to shadows, noise, and background images.
