Unifies the position and angle of objects or just puts the angle of the object into Context (if this option is ticked). Remove background needs to be used before Unifier and have the same background color selected.

Contrast equalisation
Equalises the contrast using the CLAHE algorithm, which works with a histogram of a pixel and its surroundings (depending on the kernel size). Clip limit determines the value at which the histogram is clipped. Details in the OpenCV documentation for CLAHE and histogram equalisation.

It is usually better to use odd numbers for the kernel size, so that the neighborhood of pixels is symmetric around the middle. |

The standard values from 1 to 10 can be set using the slider, but e.g. for the Erosion and Dilation functions you can set even a larger kernel by simply typing the desired number in the input field. |
Iterations
This parameter controls how many times a given transformation is performed. This is used e.g. for the Erosion or Dilation functions, which are local transformations whose output changes when they’re applied on the image multiple times subsequently.

Active
Using the ‘Active’ checkbox, the whole module can be enabled or disabled. You can also enable/disable each function individually. When new module or individual function is created, it is automatically set as active.
