gradientmagnitude

Syntax: gradientmagnitude(input image, output image, spatial sigma, gamma)

Calculates norm of Gaussian gradient of image. The output image can be the same than the input image.

This command can be used in the distributed processing mode. Use distribute command to change processing mode from local to distributed.

Arguments

input image [input]

Data type: uint8 image, uint16 image, uint32 image, uint64 image, int8 image, int16 image, int32 image, int64 image, float32 image

Input image.

output image [output]

Data type: float32 image

Output image.

spatial sigma [input]

Data type: real

Default value: 1

Standard deviation of Gaussian derivative kernel.

gamma [input]

Data type: real

Default value: 0

Scale-space scaling exponent. Set to zero to disable scaling.
