Creating Experiments

To create a new Experiment, do the following:

  1. Go to Create/Create Experiment.

  2. Open the experiment editor either by clicking icon_experiment_editor in the toolbar, or via Windows/Experiment Editor.

  3. Open the outliner by either clicking icon_outliner in the toolbar, Alt + O or via Windows/Outliner.

  4. In the outliner select the new experiment.

  5. In the experiment editor open the General tab to rename the experiment to your needs.

Configuring Experiments

Setting up an experiment can feel a bit complicated at the beginning, but will become more intuitive once you understood, VIAN’s way of looking at things.

Once you have configured your experiment as described in _creating_experiments you can edit the experiment in the experiment editor. You should now see this widget:

Experiment editor in VIAN.

The Experiment set-up of VIAN.

Indicated Information:

  • 1: Under «Classification Objects» you find the objects - be they conceptual like Soundtrack or actual like Male Protagonist - that are being classified in your project.

  • 2: If you click one of the objects, you can define on which targets you want to classify this object; targets are mainly Segments and Screenshots.

  • 3: Under «Attached Vocabularies» you see the vocabularies that are selected to the respective object. Since in this example the object «Global» is selected, a lot of vocabularies are attached to it, for other objects the selection might well be much smaller.

  • 4: Lastly, under 4 you see the patterns that the Semantic Segmentation is able to detect. Since this Algorithm has no knowledge of the real-world properties of the things it is able to detect, you have to manually attach these to the correct object (it does e.g. not know that «hats» belong to entities such as people etc. It simply detects objects (i.e. pixel-structures) that look like hats).

To add classification objects, do the following:

  1. Open the experiment editor either by clicking icon_experiment_editor in the toolbar, or via Windows/Experiment Editor.

  2. In the Classification tab, add a classification object by typing its name into the textbox on the bottom.

  3. On the right side, select the Vocabularies tab.

  4. In Attached Vocabularies tick all vocabularies with which you want to classify the created classification object.

Note

Classification Objects A classification object may be both a conceptual or true object which you want to classify, and may have a pixel representation within the film material. E.g. A classification object could be named Figure or Ground, since only the Figure can have an emotional state, the vocabulary Emotion would only be used to classify Figure. A conceptual classification object could for example be Soundtrack.
