Reading a Bubble Sheet with Image Processing Toolkit

I'm trying to read data off of a homemade bubble sheet. In my code so far, I detect the bubbled circles within the name and answer segments; however, I do not know how to interpret the circles with MATLAB. My main concern as of this moment is pulling the name information. Below is my code and bubble sheet as of this moment.
clear all;
clc;
myImage=imread('C:\Users\Joshua\Desktop\Independent Study Project Resources\ScantronFormatV3Filled.png');
imshow(myImage);
myImageGray = rgb2gray(myImage);
imshow(myImageGray)
[BW,maskedImageName] = SegmentImageFunctionName(myImage);
imshow(maskedImageName)
[centers,radii] = imfindcircles(maskedImageName,[9 14],'ObjectPolarity',...
'dark','Sensitivity',0.97,'EdgeThreshold',0.778);
h1 = viscircles(centers,radii);
[BW,maskedImageBubbles] = SegmentImageFunctionBubbleQuestions(myImage);
[centers,radii] = imfindcircles(maskedImageBubbles,[9 12],'ObjectPolarity',...
'dark','Sensitivity',0.97,'EdgeThreshold',0.778);
h2 = viscircles(centers,radii);
