For this problem your code will need to do the following:
Accurately determine the number of each coin type present. Use variable names nDimes, nNickels, nQuarters, and nFiftyCents.
Calculate the total $ value of coins present. Use variable name USD

The code:

testImageIdx = randi([1,3]);
testCoinImage = imread("testCoinImage" + testImageIdx + ".png");

imshow(testCoinImage);
title("Original Coin Image");
[testcoinMask, MaskedtestCoin] = segmentCoin(testCoinImage);

se = strel(‘disk’, 20, 0);
testCoinMask = imfill(testcoinMask, ‘holes’);
testCoinMask = imerode(testcoinMask, se);

imgFilt = imgaussfilt(MaskedtestCoin, 0.5, ‘Padding’, "circular", ‘FilterDomain’, "frequency", ‘FilterSize’, 3);
faceEdgeMask = edge(imgFilt, "sobel", 0.05, "both");

faceEdgeMask(~testcoinMask) = false;
imshow(faceEdgeMask);

validCoinMask = Bw2 & testcoinMask;
set = strel("disk", 2, 0);
validCoinMask = imdilate(validCoinMask, set);
montage({testcoinMask, validCoinMask});

USD = (nDimes * 0.10) + (nNickels * 0.05) + (nQuarters * 0.25) + (nFiftyCents * 0.50);
