Methods

Method	Description
ConvolutionMatrix	Overloaded. Initializes a new instance of ConvolutionMatrix.
Equals	Overloaded. Compares two objects to determine if they are equal. (Inherited from Object)
Fill	Fills the current ConvolutionMatrix with a specified value.
GetHashCode	Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ReferenceEquals	Determines whether the specified Object instances are the same instance. (Inherited from Object)
ToString	Overriden. Returns a String that represents the current Object.
this[]	Overloaded. Gets or sets the element at the specified index.

Properties

Remarks

The Convolution is a method used in the treatment of image; it acts on each pixels of the image.

The Convolution method is a treatment of a matrix to  one other; the first one is the image to be treated, the second one is the filter also known under the name of "kernel".
