Use an Intermediate Detector When It Simplifies the Next Step
An extra processing stage is worthwhile when it converts raw input into information that makes the downstream module's task simpler. For example, an aisle-marker detector in a warehouse robot pipeline can provide marker-location information before route planning, allowing the planner to use a focused representation instead of interpreting raw camera frames.
