IP Command

IP commands perform image processing work, such as image cleanup, format conversion, or feature detection.

Remarks

IP Commands are used to construct IP Profiles, and are also used as stand-alone properties on some Grooper types.

Some IP Commands modify the images they process, while other IP Commands simply detect features in an image, without modifying the image in any way.

Each IP Command defines a set of supported pixel formats. If an image with an unsupported pixel format is encountered, the command will take no action.

List of IP Command Types

Name	Description
Border Cleanup
Auto Border Crop	Detects black borders around the edge of an image, crops the image to remove the border, and cleans up remaining edge artifacts.
Auto Border Invert	Detects dark borders around the edge of an image and inverts or fills the area occupied by the border.
Border Fill	Drops out artifacts around the edge of an image.
Crop	Crops borders of an image by a specified amount.
Color Adjustment
Adjust Saturation	Adjusts the saturation (color intensity) in an image.
Adjust Tint	Adjusts the tint in an image.
Auto Adjust Levels	The Adjust Levels command corrects the tonal range and color balance by adjusting the shadow, midtone, and highlights of an image.
Auto Color Balance	Automatically corrects the color and contrast of an image.
Auto White Balance	Automatically adjusts the white point in an image.
Brightness Contrast	Modifies the brightness and/or contrast of an image.
Color Dropout	Replaces pixels in a specific color range with a replacement color.
Colorize	This command can be used to replace the hue, saturation and luminance values in an image with those of the specified base color.
Contrast Stretch	Adjusts the contrast of an image so that the lightest pixels are 100% white, and darkest pixels are 100% black.
Gamma Adjust	Controls the gamma correction level.
Invert	Inverts images which are negated.
Posterize	Generates an image made up of primary and secondary colors of the source image.
Solarize	Use this command to adjust the curves to generate a classic "solarize" effect.
Swap Channels	Converts RGB to BGR.
Feature Detection
Barcode Detection	Detects and reads barcode data.
Blank Page Detection	Detects whether an image is blank.
Box Detection	Detects checkboxes in an image and reads their check state.
Color Detection	Detects whether an image contains color, grayscale, or black and white content, optionally converting the image to the detected color depth.
Corner Detection	Detects corners formed by lines in an image.
Edge Detection	Performs Canny edge detection.
Hough Lines	Detects lines at arbitrary angles in an image using a Hough Transform.
Line Detection	Detects the horizontal and vertical line structure in a document image.
Patch Code Detection	The Detect Patch Codes command is used to determine if an image contains a patch code. This command is frequently used for Separation. This command returns true if a patch code is detected and false if one is not.
Shape Detection	Detects regions within an image which are similar to a sample image.
Sticky Note Detection	Detects color sticky notes, optionally flagging the pages on which they are detected.
Feature Removal
Barcode Removal	Removes barcodes from an image.
Blob Removal	Removes blobs from the image which meet specific size and fill requirements.
Box Removal	Removes checkboxes from an image.
Halftone Removal	Removes halftone regions from an image.
Hole Punch Removal	Removes circular hole punch artifacts from an image.
Line Removal	Removes horizontal and vertical lines from an image.
Negative Region Removal	Detects rectangular negated regions in an image and either inverts or removes them.
Scratch Removal	Digitally removes scratches occurring on film-based media such as microfilm, microfiche, aperture cards, or 35mm slides.
Shade Removal	Removes rectangular shaded regions from a color or grayscale image.
Shape Removal	Detects and removes regions of an image which match one or more trained image templates.
Speck Removal	Removes small specks from an image.
Format Conversion
Auto Convert	Changes the color depth of an image to match the content of the image.
Convert	Changes the color format of an image.
Threshold	Converts an image to black and white using a variety of thresholding methods.
Image Analysis
Analyze Photo	Extracts a set of classification features from the visual content of an image.
Auto QA	Automatically flags images which meet certain criteria, such as being too dark, too light, or too busy.
Compute Moments	Calculates Hu Moments for an image.
Extract Features	Divides an image into an NxN matrix of cells and generates a vector of N*N features.
Histogram	Calculates an image histogram.
Measure Entropy	Measures the entropy (amount of change) in an image.
Projection Profile	Generates a projection profile.
Image Transforms
Auto Deskew	Detects the skew angle of text in an image, and rotates the image to compensate.
Auto Orient	Determines the correct orientation for an image and rotates the image by analyzing the orientation of the characters on the page.
Extract Page	Extracts a page from a carrier image.
Resize	Resizes an image.
Rotate	Rotates an image by a given angle.
Warp	Extracts a quadrilateral shape from an image, and warps it to a rectangular output image.
Miscellaneous
Binarize	Converts an image to 8-bit black and white using various thresholding methods.
Classify Image	Compares an image against a set of sample images and classifies the image based upon which sample image it is found to be most similar to.
Dilate Erode	Applies a dilation (thicken) or erosion (thinning) filter to the image.
Execute Profile	Use this command to execute another IP Profile.
Extract Channel	Extracts a single channel from the source image..
Filter	Applies a filter to an image.
Randomize Defects	Applies randomized defects to an image.
