This function creates a synthetic image where the dimensions can be defined.

Parameter

Description

Width

Width in x of the image.

Height

Height in y of the image.

Z Slices

Number of z slices of the image. If the value is > 1, it will become a Z-stack image.

Channels

Number of channels of the image, if value is > 1, it will become a multi-channel image.

Time Slices

Number of time slices, if value is > 1, it will become a time series image.

Min. Gray Value

Minimum Gray Value for generation.

Max Gray Value

Maximum Gray Value for generation.

Pixel Type

Specifies the pixel type of the image.

Pattern

-

Uniform

All pixels of the image have identical Min. Gray Value.

-

2D Gray Scale Vertical

The image shows a gray scale with values between Min. Gray Value and Max. Gray Value from top to bottom.

-

2D Gray Scale Horizontal

The image shows a gray scale with values between Min. Gray Value and Max. Gray Value from left to right.

-

Ramp

The image shows a ramp with values between Min. Gray Value and Max. Gray Value starting from each corner of the image to the center.

-

Gaussian

The image shows a Gaussian shaped grayscale with values between Min. Gray Value and Max. Gray Value starting from the borders of the image to the center.

-

Checkerboard

The image shows a checkerboard where the “dark” fields have Min. Gray Value and the “bright” fields have Max. Gray Value.

-

Cosine Checkerboard

The image shows a checkerboard where the “dark” fields have Min. Gray Value and the “bright” fields have Max. Gray Value overlaid with a cosine modulation.

-

Chirp Cosine

The image shows a cosine pattern where the “dark” fields have Min. Gray Value and the “bright” fields have Max. Gray Value overlaid with a chirp modulation.

-

Chirp Checker

The image shows a checkerboard where the “dark” fields have Min. Gray Value and the “bright” fields have Max. Gray Value overlaid with a chirp modulation.

-

Random Spheres

a 3D (Z stack) image is created which contains Number of Spheres spheres with Sphere Diameter diameter which are randomly distributed in the image.

-

Sphere Array

a 3D (Z stack) image is created which contains Number of Spheres spheres with Sphere Diameter diameter which are equally distributed in the image.

-

Single Sphere

a 3D (Z stack) image is created which contains a single sphere with Sphere Diameter diameter which is positioned in the center of the image.

Sphere Diameter

Diameter of the created spheres.

Number of Spheres

Number of spheres which are generated in the 3D image.
