HistogramValey¶

class HistogramValey(*args, **kwargs)¶

Bases: pybind11_object

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 .

Overloaded function.

__init__(self: visp._visp.core.HistogramValey) -> None
__init__(self: visp._visp.core.HistogramValey, lvl: int, val: int) -> None

__eq__(self, v: visp._visp.core.HistogramValey) → bool¶

Comparison operator.

Parameters:

v: visp._visp.core.HistogramValey¶: Gray level histogram valey to compar.

__init__(*args, **kwargs)¶

Overloaded function.

__init__(self: visp._visp.core.HistogramValey) -> None

__init__(self: visp._visp.core.HistogramValey, v: visp._visp.core.HistogramValey) -> None

getLevel(self) → int¶

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

Note

See getValue()

Returns:: Location of the valey or gray level.

getValue(self) → int¶

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

Note

See getLevel()

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

set(self, lvl: int, val: int) → None¶

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

Note

See setLevel() , setValue()

Parameters:

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

setLevel(self, lvl: int) → None¶

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

Note

See setValue() , set()

Parameters:

lvl: int¶: Location of the valey or gray level.

setValue(self, val: int) → None¶

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

Note

See setPosition(), set()

Parameters:

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