AverageImages
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.

Hardware Acceleration
This operation is optimized for SSE2 technology for pixels of types: UINT8, UINT16, REAL.
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 here: Error Handling
| Error type | Description |
|---|---|
| DomainError | Image sizes are not equal in AverageImages. |
| DomainError | Image formats are not the same in AverageImages. |
