Methods
  NameDescription
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.

Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodIsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.)
Public Extension MethodTo(Type)Overloaded.
Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime.

Remarks

The class is used to accumulate statistical values about images, like histogram, mean, standard deviation, etc. for each HSL color channel.

The class accepts 24 and 32 bpp color images for processing.

Sample usage:

Copy
// gather statistics
ImageStatisticsHSL stat = new ImageStatisticsHSL( image );
// get saturation channel's histogram
ContinuousHistogram saturation = stat.Saturation;
// check mean value of saturation channel
if ( saturation.Mean > 0.5 )
{
    // do further processing
}
