This view offers the possibility to evaluate the quality of the registration/mapping of two given images by visual inspection. This can either by used to assess the visual quality of a registration or to assess how well the image contents are already aligned by default. To achieve the latter, one may select no registration. Then the images will be displayed in evaluation mode assuming an identity transform (so no mapping). It is one of several MatchPoint registration plug-ins.
(1) The currently selected registration that should be used to map the moving image for evaluation. Click to change. If no registration is selected, a direct evaluation will be performed.
(2) Reset button will remove the currently selected registration.
(3) Auto select option. If active the view will try to deduce and automatically select (if loaded in the application) the moving and target image when the registration changes. The view assumes that the moving and target images used to determine the registration should be used.
(4) The currently selected moving data. Click to change.
(5) The currently selected target data. Click to change.
(6) Start/Stop button used to activate/deactivate the evaluation. This button become active when at least the moving and the target image are selected.
(7) Selection of the visualization style. (only visible if evaluation is active)
(8) Style specific settings. (only visible if evaluation is active)
If the evaluation view is active you can choose between different modes of visualization. For more details see Visualization styles .
To stop the evaluation mode, you may use the "Stop evaluation" button or just close the evaluation view.
Important note: Please be aware, that a visual inspection of registration quality is only a weak surrogate for a thorough accuracy analysis based on representative and suitable ground truth data. From a visually good mapping you can not deduce a correct registration. This is especially true if the degrees of freedom of the registration increases. For a rigid registration it might by feasible to discern correct and incorrect registration. But for none rigid registrations you definitely you should use this view only for first visual inspection (to check if it SEEMS to do the right thing and is worth further exploration) or illustrating the registration effect for registration you have assessed in a sound way.
You can choose from the following visualization styles to evaluate the registration/mapping quality:
