A method for testing a perception system is disclosed. The method includes detecting, by a processor, one or more objects in a composite image, the composite image including a first image and at least a portion of a second image. A first set of objects are detected in the first image. Further, the method includes comparing, by the processor, a second set of objects of the one or more objects detected in the portion of the second image with a set of previously detected objects in the portion of the second image. Furthermore, the method includes validating, the performance of the processor in the detection of the first set of objects in the first image by ensuring the second set of objects detected in the at least a portion of a second image matches the set of previously detected objects in the portion of the second image.

An actuation valve for a hydraulically-operated fuel injector includes an actuator having a plunger and a spool valve coupled to the plunger. The spool valve includes a high pressure port and is operable by the actuator to selectively place the high pressure port or the low pressure port in fluid communication with an injection mechanism of the injector.
