Stereo Scan 440 - DCU

Sobel
Performs a non-directional edge detection by using a combination of
horizontal and vertical edge detection.
Average
Smoothes the image using a unity kernel.
Gaussian
Smoothes the image using a kernel with weights similar to a Gaussian
(bell) function.
Image Detect
This function defmes threshold criteria.
Black
Any pixel in the image store with a value less than the black threshold
percentage will be coloured red.
White
Any pixel in the image store with a value greater than the white
threshold percentage will be coloured red.
Grey
Any pixel in the image store with a value greater than the black
threshold percentage and with a value less than the white threshold
percentage will be coloured red.
Black Threshold
This slider bar controls how much of the image is detected when the
Image Detect is either Black or Grey.
White Threshold
This slider bar controls how much of the image is detected when the
Image Detect is either White or Grey.
Calc Area Fraction
This button initiates an area fraction calculation based on the detected
area defmed by the Image Detect State and the Black and White Slider
bars.
Area Fraction
The result of a calc area fraction is displayed as a percentage of the
image store.
