摘要：The present disclosure teaches a system for analyzing ultrasonic image thatprovides an output of a measurement of muscle width from an ultrasonic image input ofan outline of a muscle from an animal or carcass. The muscle that is used in the preferred

embodiment is the longissimus dorsi muscle when an ultrasonic scan is taken in atransverse direction relative to the backbone. The analysis is done with a computer thatreceives the electronic input of rows and columns of gray level pixel data from anultrasonic scan image of the outline of the muscle of the animal or carcass. The softwareis set to select a region of the ultrasonic image input to analyze to determine a first edgeof the muscle. The selected region is divided into subregions Sj. J designates a row andranges between 1 and n. K designates a column and ranges between 1 and o such that ois greater than 1. The subregions are aligned in rows and columns throughout theultrasonic image input. The software calculates a sum of the gray level pixel data for eachof the subregions Sj,k then compares the sums to determine which of the subregions Sj,khas the highest sum within each row j. The software defines a position of the first edge ofthe muscle by comparing the highest sum within each row j. This position is then used tocalculate a relative muscle width when compared to a defined second edge of themuscle. The second edge can be defined as one edge of the selected region of theultrasonic image input or it can be defined using the same steps used to define the firstedge.
