CImCombine:MaskedMean
The MaskedMean method merges the pixel values excluding 0-valued pixels from the distribution at each point. The value 0 is therefore a mask value.
CImage = CImCombine:MaskedMean( CImageSet ) |
CImageSet contains the collection of images to be combined.
CImage is a new image created by this method.
On success, this method returns a new CImage.
On failure, this method returns nil.
Each pixel in the output image is the mean value of all images except for those with a value of zero (0).
Suppose a CImageSet named S exists. The following script combines the images by the MaskedMean method. The images are normalized by the Median statistic computed inside the central 10% of the image:
|
-- create a CImCombine object |
|
-- central 10% of the image |
|
-- specify CImage and CRect to measure |
|
-- use the MmClip as the normalization statistic |
|
-- scale to normalize the image set |
|
-- combine the image set and return a new image |
|
-- show the new image |
|
-- when done with S, remove it from memory |
