Methods defined here:
- __init__(self, xsize, ysize)
- Constructor
xsize -- the x dimension of the generated images
ysize -- the y dimension of the generated images
- generate_lowpass(self, sigma_x, sigma_y)
- generate_poly2d(self, c=0.0, c_x=0.0, c_y=0.0, c_xx=0.0, c_xy=0.0, c_yy=0.0)
- Generate an image from a 2d polynomial
ima(x,y) = c+c_x*x+c_y*y+c_xx*x*x+c_xy*x*y+c_yy*y*y
- generate_random_gauss(self, dispersion, mean)
- Generate a cube with noise distributed normally around mean,
with rms dispersion
