-class BalancedPixelInterpolation from Image inherits PixelInterpolation from Image
-
- ---Purpose: The class BalancedPixelInterpolation is used to compute a
- -- SubPixel value on non integer Image coordinate
- -- BalancedPixelInterpolation redefined a new method to compute
- -- a SubPixel value .
- -- The value is the proportional to the distance of the
- -- four nearest Image Pixel.
- -- A B
- -- SubPixel
- -- C D
- -- If VA, VB, VC, VD is the value of the four nearest Image
- -- Pixel, if ColDelta and RowDelta is the distance from non
- -- integer coordinate (FX,FY) to the upper left nearest Image
- -- Pixel , then :
- -- ColDelta = FX - XA ;
- -- RowDelta = FY - YA ;
- -- CAB = ColDelta*( VB - VA ) + VA
- -- CCD = ColDelta*( VD - VC ) + VD
- -- V = RowDelta*( CCD - CAB ) + CAB
- -- is the Image SubPixel value on non integer
- -- coordinate (FX,FY).

-class BilinearPixelInterpolation from Image inherits PixelInterpolation from Image
-
- ---Purpose: The class BilinearPixelInterpolation is used to compute a
- -- SubPixel value on non integer Image coordinate
- -- BilinearPixelInterpolation redefined a new method to compute
- -- a SubPixel value .
- -- The value is the bilinear interpolation of the
- -- four nearest Image Pixel.
- -- If V1, V2, V3, V4 is the value and (X1,Y1) , (X2,Y2),
- -- (X3,Y3), (X4,Y4) the coordinates of the four nearest
- -- Image Pixel then first we solve :
- -- V1 = a*X1 + b*Y1 + c*X1*Y1 + d
- -- V2 = a*X2 + b*Y2 + c*X2*Y2 + d
- -- V3 = a*X3 + b*Y3 + c*X3*Y3 + d
- -- V1 = a*X4 + b*Y4 + c*X4*Y4 + d
- --
- -- and V = a*FX + b*XY + c*FX*FY + d
- -- is the Image SubPixel value on non integer
- -- coordinate (FX,FY).

-class Convertor from Image
-
- ---Purpose: This class is used to convert :
- -- a PseudoColorImage to a ColorImage
- -- a ColorImage to a PseudoColorImage
- -- a PseudoColorImage to a PseudoColorImage with a
- -- different ColorMap.
- --
- -- To convert a PseudoColoImage to a ColorImage we use
- -- the PseudoColoImage ColorMap to compute the Color of each
- -- Image Pixel ( Lookup operation ) , the resulting image
- -- look similar as the original image.
- --
- -- To convert a ColorImage to a PseudoColorImage or
- -- a PseudoColorImage to another PseudoColorImage we use
- -- Dithering.
- --
- -- A dither operation is an inverse lookup operation.For
- -- example if we want to dither a ColorImage to a
- -- PseudoColorImage, for each Pixel in the ColorImage we search
- -- in the PseudoColorImage ColorMap the Entry with the nearest
- -- Color, then we write the ColorMap Entry Index in to the
- -- PseudoColorImage. The result is a PseudoColorImage that when
- -- it is displayed using its own ColorMap it will look as much
- -- like the original ColorImage as possible.
- --
- -- This class provides 2 Dithering method.
- --
- -- DM_NearestColor : this dithering method is the simplest
- -- one ,it just finds the nearest entry in the ColorMap.
- -- This algorithm provide no provision for eliminating unwanted
- -- contours in the dithered image.This algorithm is much
- -- faster on ColorRamp and ColorCube than on Generic
- -- ColorMap.Indeed on ColorRamp and ColorCube ColorMap the
- -- ColorMap Entry Index can be computed by using the ColorMap
- -- BasePixel and ColorDimension.
- --
- -- DM_ErrorDiffusion: In this method the difference ( error )
- -- between the original and the dithered image is distribued
- -- to the oginal image pixels immediatly to the right of and
- -- below the last pixel processed. The ErrorDiffusion method
- -- uses a "floyd-steinberg" error-distribution kernel.This
- -- algorithm is fairly time-consuming, but can greatly reduce
- -- contouring in the dithered image.

-class PseudoColorImage from Image inherits DIndexedImage from Image
-
- ---Purpose : A PseudoColorImage is a DIndexedImage associated with a
- -- ColorMap . The ColoMap is set at Creation time and then
- -- never be changed. Each Pixel in the Image ,as a IndexPixel
- -- from Aspect, match a ColoMap Entry with the same value.
-
-uses
- ColorMap from Aspect,
- Color from Quantity,
- IndexPixel from Aspect ,
- Array1OfColor from Quantity,
- HArray1OfColor from Quantity,
- LookupTable from Image,
