Measure image texture
Calculates Haralick's texture features for an image.
Description
Calculates Haralick's texture features for an image. Each pixel in the image is compared to a corresponding pixel, a defined offset away (e.g. x-offset = 1, y-offset=0, z-offset=0 to compare to the pixel immediately right of each pixel). The intensities of the pixel pairs are added to a 2D gray-level co-occurrence matrix (GLCM) from which measures of angular second moment, contrast, correlation and entropy can be calculated.

Parameters
| Parameter | Description |
|---|---|
| Input image | Image from the workspace for which texture metrics will be calculated. Texture measurements will be assigned to this image. |
| X-offset | Each pixel in the input image will be compared to the pixel a defined offset-away. This parameter controls the x-axis offset. Offset specified in pixel units unless "Calibrated offset" is selected. If using calibrated units, the offset will be rounded to the closest integer value. |
| Y-offset | Each pixel in the input image will be compared to the pixel a defined offset-away. This parameter controls the y-axis offset. Offset specified in pixel units unless "Calibrated offset" is selected. If using calibrated units, the offset will be rounded to the closest integer value. |
| Z-offset | Each pixel in the input image will be compared to the pixel a defined offset-away. This parameter controls the z-axis offset. Offset specified in pixel units unless "Calibrated offset" is selected. If using calibrated units, the offset will be rounded to the closest integer value. |
| Calibrated offset | When selected, offsets are specified in calibrated units. Otherwise, offsets are assumed to be in pixel units. |
