This menu shows another possibility how to select HALCON operators via suggestions. Assuming that you have already selected an operator in a previous step, depending on this operator, the following suggestions are offered.
Suggestions are separated into groups as described below.
| Menu Entry | Description | Shortcut |
| Alternatives | Suggests alternative operators. For example, replace mean_image with operators such as binomial_filter, gauss_filter, or smooth_image. | |
| See also | Shows operators that have some connection to the current operator. For example, the operator gen_lowpass, which is used to create a lowpass filter in the frequency domain, is a reasonable reference to a Gaussian filter. | |
| Predecessors | Many operators require a reasonable or necessary predecessor operator. For example, before computing junction points in a skeleton (junctions_skeleton), you have to compute this skeleton itself (skeleton). | |
| Successors | Shows possible successor operators. Image processing tasks often result in a “natural” sequence of operators. For example, you use a thresholding after executing an edge filter or you execute a region processing (for example, morphological operators) after a segmentation. | |
| Keywords | Opens the tab card Index of the help window. More info | Ctrl+Shift+H,K or Ctrl+Shift+H,Ctrl+Shift+K |
