Field Details

eps

public double eps

Used to avoid a divide by zero error when dividing by the standard deviation. Only used with NCC. Smaller values are more mathematically accurate but make it more sensitive to floating point error. This has been tuned to work with pixel values that have been scaled to -1 to 1.

normalizeInput

public boolean normalizeInput

If true then the input will be normalized so that it has zero mean and a max absolute value of one. Reduces numerical issues.

Constructor Details

NCC

public NCC()

Method Details

checkValidity

public void checkValidity()

Description copied from interface: Configuration

Checks to see if the configuration is valid. If it is invalid, throw an exception explaining what is incorrect.

Specified by:

checkValidity in interface Configuration

setTo

public ConfigDisparityError.NCC setTo(ConfigDisparityError.NCC src)
