1. An electronic device that determines a fascicle length and returns advice to a user, comprising:
at least one non-transitory storage medium that stores instructions; and
at least one processing unit that executes the instructions to:
process an ultrasound scan image to generate a processed image in order to simplify distinguishing a target muscle tissue in the processed image, wherein the processing of the ultrasound scan image comprises:
introducing noise;
thresholding;
removing a first element;
joining second elements that are larger than the first element; and
cropping the ultrasound scan image to focus on the target muscle tissue;
distinguish the target muscle tissue in the processed image;
use the processed image to determine the fascicle length of the target muscle tissue, thereby providing a determined fascicle length;
determine whether the determined fascicle length is less than or greater than a desired fascicle length; and
return the advice to the user based on the fascicle length being less than or greater than the desired fascicle length;
wherein the advice is related to increasing or decreasing the fascicle length to become more like the desired fascicle length.
