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.
(Defined by ExtensionMethods.)
Public Extension MethodToTOverloaded.
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 provides information about vertical distribution of pixel intensities, which may be used to locate objects, their centers, etc.

The class accepts grayscale (8 bpp indexed and 16 bpp) and color (24, 32, 48 and 64 bpp) images. In the case of 32 and 64 bpp color images, the alpha channel is not processed - statistics is not gathered for this channel.

Sample usage:

Copy
// collect statistics
VerticalIntensityStatistics vis = new VerticalIntensityStatistics( sourceImage );
// get gray histogram (for grayscale image)
Histogram histogram = vis.Gray;
// output some histogram's information
System.Diagnostics.Debug.WriteLine( "Mean = " + histogram.Mean );
System.Diagnostics.Debug.WriteLine( "Min = " + histogram.Min );
System.Diagnostics.Debug.WriteLine( "Max = " + histogram.Max );
