Final answer:
A computer vision system uses a camera, operator, and digitizer to predict carcass composition by analyzing captured visual images.
Step-by-step explanation:
The technique that uses a camera, an operator, and a digitizer to predict carcass composition is a computer vision system. This method involves capturing visual images and then utilizing software and algorithms to process and analyze these images for various applications, including the estimation of meat quality and characteristics in a carcass. Unlike other imaging techniques such as dual-energy X-ray absorptiometry (DEXA), magnetic resonance imaging (MRI), or ultrasound imaging which rely on different principles of operation, a computer vision system directly uses the visual data captured by the camera for analysis and interpretation.
