Detailed Description

Declaration of the valey (minimum value) in a gray level image histogram.

A valey is internally represented as a gray level and a value. The value represents the number of pixels having the gray level.

Examples

histogram.cpp.

Member Function Documentation

getLevel()

unsigned char vpHistogramValey::getLevel ( ) const

inline

Get the valey gray level. The number of pixels having this gray level is available through getValue().

Returns

Location of the valey or gray level.

getValue()

Examples

histogram.cpp.

Definition at line 119 of file vpHistogramValey.h.

References vpHistogramPeak::level.

getValue()

unsigned vpHistogramValey::getValue ( ) const

inline

Get the valey number of pixels having a same gray level. The corresponding gray level is available through getLevel().

Returns

Number of pixels having the same location or gray level.

Comparison operator.

Parameters

v	: Gray level histogram valey to compar.

set()

void vpHistogramValey::set ( unsigned char lvl, unsigned val )

inline

Set the valey gray level and number of pixels at this location.

Parameters

lvl	: Location of the valey or gray level.
val	: Number of pixels having the same location or gray level.
