To create a MATLAB code for detecting counterfeit £10 notes based on RGB color values, you'll need to follow several steps. This solution assumes you have a way to input or measure the RGB values of the £10 notes you want to test. The actual RGB values for genuine £10 notes must be known or determined through analysis of genuine notes. For the purpose of this example, let's assume hypothetical RGB values for a genuine £10 note are (R: 100, G: 150, B: 200). In practice, these values should be determined through careful analysis of multiple genuine notes to account for variations in printing.
Here's a basic approach to designing such a system:
Step 1: Define Genuine £10 Note RGB Values
First, define the RGB values that represent a genuine £10 note. These values should be determined through analysis of genuine notes.
% Define the RGB values for a genuine £10 note
genuineRGB = [100, 150, 200]; % Example values (R, G, B)
Step 2: Input the RGB Values of the Notes to Be Tested
You mentioned entering about 30 random £10 notes for testing. For simplicity, let's input these RGB values into a matrix where each row represents a note, and the columns represent the R, G, and B values, respectively.
% Example input for 30 notes (randomly generated for this example)
% In practice, you would replace this with actual measured values
testRGB = randi([0, 255], 30, 3); % Generating random RGB values for 30 notes
Step 3: Compare Each Note's RGB Values to the Genuine Values
Determine a threshold for how much deviation from the genuine RGB values is acceptable. This threshold can be adjusted based on how strict or lenient you want the detection to be.
% Threshold for deviation in RGB values
threshold = 20; % Allowable deviation in each RGB component
% Initialize a logical array to mark each note as genuine (1) or counterfeit (0)
results = zeros(size(testRGB, 1), 1);
% Loop through each note and compare its RGB values to the genuine RGB values
for i = 1:size(testRGB, 1)
deviation = abs(testRGB(i, :) - genuineRGB);
if all(deviation <= threshold)
results(i) = 1; % Mark as genuine
else
results(i) = 0; % Mark as counterfeit
end
end
Step 4: Display the Results
Finally, display which notes passed the test and which ones are suspected to be counterfeit.
for i = 1:length(results)
if results(i) == 1
fprintf('Note %d: Genuine\n', i);
else
fprintf('Note %d: Counterfeit\n', i);
end
end
