Classification
Owning Palette: Machine VisionInstalled With: NI Vision Development ModuleUse Classification VIs to identify unknown objects by comparing significant features to a set of features that conceptually represent classes of known objects.
| Palette Object | Description |
|---|---|
| IMAQ Read Classifier File |
Reads a classifier session from the file specified by File Path. |
| IMAQ Classify |
Classifies the image sample located in the given ROI. |
| IMAQ Dispose Classifier |
Destroys a classifier session and frees the space it occupied in memory. You must call IMAQ Dispose Classifier when the application no longer needs the session. This VI is required for each classifier session created. |
| IMAQ Add Classifier Sample |
Assigns a new image sample to the specified class in Classifier Session. The new sample is based on an ROI in the image. The sample is assigned to a specific class. |
| IMAQ Get Classifier Sample Info |
Retrieves the thumbnail image and class label of the sample at the specified index. |
| IMAQ Change Sample Class |
Labels the sample at the index specified by Sample Index. |
| IMAQ Delete Classifier Sample |
Deletes the sample at the index specified by Sample Index. |
| IMAQ Write Classifier File |
Writes a classifier session to the file specified in File Path. This VI saves the exact state of the classifier session. |
| IMAQ Classifier Accuracy |
Provides information about the accuracy and predictive value of the trained classifier. |

| Classifier Types |
Use the Classifier Types VIs to create specific types of classifiers and perform classifier-specific options. |
| Classifier Engines |
Use the Classifier Engines VIs to train and configure classifier sessions. |
