Detailed Description

Notes.

• if this file is not in Templates, gcc 2.7 does not instantiate.
• even if this file is in Templates, SunPro 5.0 will fail to instantiate symbols whose signatures contain a parameter of the form "type * const *". hence the 'unpro_const' macro. fsm.

#define thePixel	(		b,

	)		as_float(b[x][y])

Convolves the image with the smoothing kernel.

sub_area_ is used to smooth pixels lying in a border of size width_.

Meaning of sub_area_[x] : It is the probability that the variable will assume a value <= x in the distribution function. It is the hashed area under the distribution profile.
