Detailed Description

HxValue L_HXIMAGEREP HxIdentMaskStDev ( HxImageRep im,

HxImageRep mask,

HxPoint p,

HxSizes size,

int label

)

Compute the standard deviation of all pixels in "im" identified by "mask".
"mask" is assumed to be an identification image with pixel type short. The function considers all pixels within the area starting at point "p" with given "size" and a value equal to label.
Implementation specifics :

Pattern : Export operation with an extra image
Variation : Translation invariant, 1 phase export operation with an extra image
The pixel functor : HxExportExtraIdentMaskStdev
Instantiations : HxInstExportExtraIdentMaskStdev_c
