FIL.ImageDifferenceImage

Computes an image of differences between a moving pattern and the input image.

Namespace:FilNet
Assembly:FIL.NET.dll

Syntax

C++
C#
 
public static void ImageDifferenceImage
(
	FilNet.Image inImage,
	FilNet.Image inPatternImage,
	FilNet.DistanceMeasure inDistanceMeasure,
	FilNet.Image outImage
)

Parameters

Name Type Range Default Description
inImageFilNet.ImageInput image.
inPatternImageFilNet.ImagePattern to be compared with input image.
inDistanceMeasureFilNet.DistanceMeasureMeasure of distance.
outImageFilNet.ImageOutput image.

Description

The operation computes the difference between inImage and inPatternImage. The inPatternImage is aligned at each location of the inImage and the similarity between the inPatternImage and the corresponding part of the inImage is estimated using the inDifferenceMeasure as in ImageDifference filter. The result is stored in the pixel of the outImage that corresponds to the location at which the center of inPatternImage was aligned to the inImage.

Examples

A sample inImage.

A sample inPatternImage.

The resulting outImage.

The locations in the inImage corresponding to the darkest points of the outImage.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8 (for inDistanceMeasure = MeanError).

This operation is optimized for SSE3 technology for pixels of types: UINT16 (for inDistanceMeasure = MeanError), UINT8 (for inDistanceMeasure = MeanSquaredError), REAL.

This operation is optimized for SSE4 technology for pixels of types: INT16, UINT16 (for inDistanceMeasure = MeanSquaredError).

This operation is optimized for AVX2 technology for pixels of types: UINT8, INT16, UINT16, REAL.

This operation is optimized for NEON technology for pixels of types: UINT8, UINT16 (for inDistanceMeasure = MeanError), INT16 (for inDistanceMeasure = MeanError), REAL.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Hardware acceleration settings may be manipulated with Settings class.
