The *Create Tool* is a general purpose image creation tool, which
can be called from the image calculator sub-tool, for the
generation of simulated data of various types. It has the following
functional capabiltites.

**rect**- create rectangle CP(width, height, cx, cy, ax, ax).**chequer**- create chequer board CP(width, height, ax, ay). Useful for evaluating edge and corner detectors and for masking geometric regions.**noise**- create noise image CP(width, height, ax, ay, noise). The generated image has Gaussian uniform random noise and is intended for Monte-Carlo algorithm evaluations.**rds**- random dot stereogram noisy stereo image CP(width, height, ax, ay, ex, ey, noise).**delta**- generate a delta function CP(width,height,cx,cy).**ellipse**- generate an ellipse to subpixel accuracy CP(width, height, cx, cy, ax, ay).**elipsiod**- generate an ellipsoid to subpixel accuracy CP(width, height, cx, cy, ax, ay).**sellipse**- generate a super ellipse to subpixel accuracy CP( width, height, cx, cy, ax, ay, ex, ey).**shade**- compute shaded image from 3D surface TOS image CP(slant,tilt) using simple Lambertian reflection assumptions.**fgabor**- construct gabor filter in fourier domain with central frequency, bandwidth and orientation given by CP(gb_k, gb_b, theta).**fshade**- constuct fourier transform of approximate shading convolution funtion CP(slant,tilt) which matches TOS roi, allows subsequent Shape-from-shading using a variation on the technique suggested by Pentland.

In addition simple asci matricies can be read from file and converted
into images using the *input* *output* facility via selection of
the appropriate filename parameters.
