AverageImages

Module:	FoundationLite

Averages two images pixel by pixel.

Name	Type	Description
inImage1	Image	First input image
inImage2	Image	Second input image
inRoi	Region *	Range of pixels to be processed
outImage	Image	Output image

Description

The operation computes the average of two images. Each outImage pixel is equal to the average of the corresponding pixels of the input images.

In multichannel (color) images each pixel channel is processed separately.

The operation requires that the images being processed have equal format and dimensions, otherwise an error with appropriate description occurs. To obtain an image of desired dimensions one can use ResizeImage or CropImage filter. To alter the pixel type of an image one can use ConvertPixelType filter. ConvertToMultichannel and AverageChannels filters allow to alter the number of image channels.

Examples

AverageImages performed on the sample images.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT16, UINT16, REAL.

This operation is optimized for AVX2 technology for pixels of types: UINT8, SINT16, UINT16, REAL.

This operation is optimized for NEON technology for pixels of types: UINT8, SINT8, UINT16, SINT16, SINT32.

This operation supports automatic parallelization for multicore and multiprocessor systems.

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type	Description
DomainError	Image formats are not the same in AverageImages.
DomainError	Image sizes are not equal in AverageImages.
DomainError	Region exceeds an input image in AverageImages.
