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.

Definition at line 68 of file vpHistogramValey.h.

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.

Definition at line 137 of file vpHistogramValey.h.

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

const

Comparison operator.

Parameters

v	: Gray level histogram valey to compar.

void vpHistogramValey::set ( unsigned char  level, unsigned  value  )

inline

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

Parameters

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