    Load() error
    ProcessFrame(frame *image.RGBA) (*image.RGBA, error)
    Close() error
}
```

#### **ONNX Runtime Integration:**
```go
type ONNXModel struct {
    name      string
    modelPath string
    session   *ort.Session // Ready for ONNX Runtime
    loaded    bool
    config    map[string]interface{}
}
```
