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

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.

See also

getValue()

Examples:

histogram.cpp.

References vpHistogramPeak::level.

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.

vpHistogramValey & vpHistogramValey::operator=

(

const vpHistogramValey &

v

)

Copy operator.

Parameters

v	: Histogram valey to copy.

vpHistogramValey v1(0, 255);
vpHistogramValey v2 = v1; // Valey p2 is set to 0, 255

v

)

const

Comparison operator.

Parameters

v	: Gray level histogram valey to compar.

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.

void vpHistogramValey::setLevel ( unsigned char  lvl )

inline

Set the valey gray level. To set the number of pixels having this gray level use setValue().

Parameters

lvl	: Location of the valey or gray level.

void vpHistogramValey::setValue ( unsigned  val )

inline

Set the valey number of pixels having a same gray level. To set the gray level of this valey use setLevel().

Parameters

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