Detailed Description

Will combine the input data based on a supplied equation.

This combiner uses the ossimEquTokenizer to create unique id's for all tokens in the formula. The parser is based on the following rules:

Prog -> Expr EOF 
Expr -> Term RestExpr 
RestExpr -> + Term RestExpr | - Term RestExpr | <null> 
Term -> Storable RestTerm 
RestTerm -> * Factor RestTerm | / Factor RestTerm | <null> 
Factor -> number | R | ( Expr )

The equation string represents input images as in[i] for i = 0, 1, ..., n.
The following tokens are supported, where I, I1, I2, ..., In are inputs (either input images or
image solutions of other equations):

sin(I)                 takes the sine of the input
sind(I)                takes the sin of the input and assumes degree input
asin(I)                computes the arc-sine of input in radians (input must be normalized)
asind(I)               computes the arc-sine of input in degrees (input must be normalized)
cos(I)                 takes cosine of input
cosd(I)                takes the cosine of input and assumes input in degrees
acos(I)                computes the arc-cosine of input in radians (input must be normalized)
acosd(I)               computes the arc-cosine of input in degrees (input must be normalized)
tan(I)                 takes tangent of input
tand(I)                takes the tangent of input and assumes input in degrees
atan(I)                computes the arc-tangent of input in radians
atand(I)               computes the arc-tangent of input in degrees
sqrt(I)                takes square root of input
log(I)                 takes the natural log of input
log10(I)               takes the log base 10 of the input
exp(I)                 takes the e raised to the passed in argument
abs(I)                 takes the absolute value of the passed in value
min(I1, I2, ... In)    takes the min of all values in the list
max(I1, I2, ... In)    takes the max of all values in the list.

clamp(I, min, max)     will clamp all data to be between the min max values.
                       will set anything less than min to min and anythin
                       larger than max to max

band(I, band_index)    returns a single band image object
                       by selecting band num from input image I.  Note
                       the first argument must be an image
                       and the second argument must be a number

shift(I, rows, cols)
                       currently, the first argument must be an image
                       variable and rows, cols must be numbers
                       indicating the delta in that direction to shift the
                       input.

blurr(I, rows, cols)   Will blurr the input image I with a
                       rows-by-cols kernel.  All values are equal
                       weight.  Note the fist argument must by an image
                       variable (ex: i1, i2,....in).

conv(index, rows, cols, <row ordered list of values> )
                       this allows you to define an arbitrary matrix.  The
                       <row ordered="" list="" of="" values>=""> is a comma separated
                       list of constant values.

assign_band(I1, num1, I2, num2)
                       will take band num2 from image data I2 and assign it to
                       band num1 in image data I1.

assign_band(I1, num1, I2)
                       will take band 1 from image data I2 and assign it to
                       band num1 in image data I1.

assign_band(I, num1, num2)
                       will assin to band num1 of data I the value of num2

I1 * I2                will multiply I1 and I2
I1 + I2                will add I1 and I2
I1 - I2                will subtract I1 and I2
I1 / I2                will divide I1 and I2
I1 ^ I2                will do a power, raises I1 to I2
I1 | I2                will do a bitwise or operation

I1                   will negative of I1

Boolean ops: 1=true, 0=false
I1 > I2
I1 >= I2
I1 == I2
I1 <= I2
I1 < I2
I1 <> I2

Note:

Currently an image input is reference by the variable "in[i]" where i
represents the input image index starting from 0.  So in[1] referes to the second image
in the input source list.

Some examples:

 (in[0] + in[1])/2
 Will take image 0 and add it to image 1 and average them.

 exp(sqrt(in[0])/4)
 Will take the root of the image and divide by 4 and then raise e to that
 amount.

 128
 Will return a constant value of 128 for all input bands.

shift(0, 1, 1) - in[0]
Will shift the first input (0) by 1 pixel along the diagonal and then subtract
the original from the shifted (edge detect).

assign_band(in[1], 1, blurr(in[1], 5, 5), 2)
Will assign to the first band of input 1 the 2nd band of the 5x5 blurr of same image.

conv(0, 3, 3, -1, -2, -1, 0, 0, 0, 1, 2, 1)
Will convolve the first input connection with a 3x3 matrix.
The args are row ordered:
                         -1, -2, -1
                          0,  0,  0
                          1,  2,  1

NDVI:
N=(in[0]-in[1])/(in[0]+in[1])

For indexed-type values,like NDVI, (with limited values) it is better
to rescale between 0.0 and 1.0 and use type NormalizedFloat.

Rescaled NDVI between 0 and 1:
(N+1)/2 = in[0]/(in[0]+in[1])

With an ossimImageToPlaneNormalFilter feeding the DEM-image input, the slope at each pixel,
normalized so that 1.0 = 90 deg from vertical, is computed with:
"acosd(band(in[0],2))/90"
