Stereo Scan 440 - DCU

~
AMaxB
This function freezes the image store and then sets each pixel in the
image store to the maximum grey level from the corresponding pixels in
the image store and off screen image store.
I
Image FOter
This function defmes which of the convolution kernels is to be swept
across the image store producing a result for each pixel. The result is
then normalised to the range 0.255.
This process can give effects such as High-Pass and Low-Pass filtering.
All the Kernels are a 3 by 3 matrix of signed integers.
Sharpen 1
Sharpens the image by combining a Laplace 1 edge detection with the
original image.
Sbarpen2
Sharpens the image by combining a Laplace 2 edge detection with the
original image.
Laplace 1
Detects edges in the image by performing a Laplace b'ansfOfDl using the
4 neighbouring pixels. Laplace transfOfDlS are second order gradient
functions.
I
I
Laplace 1-
Detects edges in the image by performing a Laplace transform using the
8 neighbouring pixels. Laplace transforms are second order gradient
functions.
Bortz Edge
Detects horizontal edges in the image.
Vert Edge
Detects vertical edges in the image.
Prewitt
Perfonns a non-directional edge detection by using a combination of
horizontal and vertical edge detection.
