CImCombine:GeometricMean

The GeometricMean method merges the pixel values using the geometric mean statistic at each location. The name GeoMean is an alias for this method.

Syntax

CImage = CImCombine:GeometricMean( CImageSet )

bullet.gif    CImageSet contains the collection of images to be combined.

bullet.gif    CImage is a new image created by this method.

bullet.gif    On success, this method returns a new CImage.

bullet.gif    On failure, this method returns nil.

Remarks

Each pixel in the output image is the geometric mean of values at the same location in all the images of the CImageSet. The geometric mean assigns each pixel a weight that is inversely proportional to its value-distance from the mean. No rejection ("clipping") is performed..

Example

Suppose a CImageSet named S exists. The following script combines the images by the Mean method after normalizing their luminance by the median statistic computed inside the central 10% of the image:

C = new_imcombine()

-- create a CImCombine object

R = new_rect(10,50,10,50)

-- central 10% of the image

C:SetRelRect( R )

-- specify CImage and CRect to measure

C:SetNormStat("median")

-- use the median as the normalization statistic

C:SetNormMethod("scale")

-- scale to normalize the image set

I = C:GeometricMean( S )

-- combine the image set and return a new image

I:Display()

-- show the new image

C:delete()

-- when done with S, remove it from memory
