Syntax: noise(image, mean, standard deviation, seed)

Adds additive Gaussian noise to the image.

This command cannot be used in the distributed processing mode. If you need it, please contact the authors.

Arguments

image [input & output]

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

Image to process.

mean [input]

Data type: real

Default value: 0

Mean value of the noise to add.

standard deviation [input]

Data type: real

Default value: 0

Standard deviation of the noise to add. Specify zero to select standard deviation based on typical maximum value range of the pixel data type.

seed [input]

Data type: integer

Default value: 0

Seed value. Set to zero to use time-based seed.
