Public Methods

Method	Description
Absolute ( double input ) : double[]	Converts an array of positive and negative values to just their absolute values
Convolute ( double xx, double hh, int indicies ) : double[]	Performs 1D convolution an a given input array xx, with a convolution kernel hh
Distance ( Bgr color1, Bgr color2 ) : double	Determines the cartesian distance between two colors
Distance ( Color pixelA, Color pixelB ) : double	Returns the Cartesian Distance between from the first the second parameter
GetKernelIndicies ( double kernel, int startingKernelIndex ) : int[]	Generates the time indicies of kernel given the starting position
IntToBgr ( int color ) : Bgr	Takes an integer, returns a BGR color
IsBound ( Bitmap image, int xx, int yy ) : bool	Determines whether the given x and y coordinates are bound with in the given the given image
IsEqual ( Bgr color1, Bgr color2 ) : bool	Checks if two colors are equal
Max ( double array ) : int>.Tuple
Reverse ( double original ) : double[]
Reverse ( int original ) : int[]
SlopeFromPoints ( Point p1, Point p2 ) : double
Threshold ( double input, double threshold ) : double[]	Thresholds the input array by a factor of the maximum value. The Maximum value is defined as the maximum EXCLUDING the first and the Last - because the first and the last are implicit features All values that are less than factor*max(input) are set to zero, others are set to max

Method Details

Absolute() public static method

Converts an array of positive and negative values to just their absolute values

public static Absolute ( double input ) : double[]
input	double	values
return	double[]

Convolute() public static method

Performs 1D convolution an a given input array xx, with a convolution kernel hh

public static Convolute ( double xx, double hh, int indicies ) : double[]
xx	double	series input
hh	double	convolution kernel
indicies	int	time index of the kernel
return	double[]

Distance() public static method

Determines the cartesian distance between two colors

public static Distance ( Bgr color1, Bgr color2 ) : double
color1	Bgr	First Color
color2	Bgr	Second Color
return	double

Distance() public static method

Returns the Cartesian Distance between from the first the second parameter

public static Distance ( Color pixelA, Color pixelB ) : double
pixelA	Color	Pixel of given color from
pixelB	Color	Pixel of given color to
return	double

GetKernelIndicies() public static method

Generates the time indicies of kernel given the starting position

public static GetKernelIndicies ( double kernel, int startingKernelIndex ) : int[]
kernel	double	The convolution kernel
startingKernelIndex	int	the starting time of the kernel (-1 etc.)
return	int[]

IntToBgr() public static method

Takes an integer, returns a BGR color

public static IntToBgr ( int color ) : Bgr
color	int	an integer between 0 and 0xFFFFFF inclusive
return	Bgr

IsBound() public static method

public static IsBound ( Bitmap image, int xx, int yy ) : bool
image	System.Drawing.Bitmap	Bit map image to checked
xx	int	X position of the pixel or Column
yy	int	Y position of the pixel or Row
return	bool

IsEqual() public static method

Checks if two colors are equal

public static IsEqual ( Bgr color1, Bgr color2 ) : bool
color1	Bgr	first color
color2	Bgr	second color
