Classifier (Model Chaining)

Classifiers run on objects detected by a parent model. They must reference a previously defined model using operate_on.

models:
  - name: "vehicle-detector"
    type: "detector"
    architecture: "yolo"
    onnx_file: /path/to/vehicle_model.onnx
    label_file: /path/to/vehicle_labels.txt

  - name: "color-classifier"
    type: "classifier"
    onnx_file: /path/to/color_model.onnx
    label_file: /path/to/color_labels.txt
    operate_on: "vehicle-detector"
    operate_on_classes: [0, 2]

Field	Description
operate_on	Required. Name of the parent detector. Must appear earlier in the list.
