How to extract x and y values from bounding box?

%test image%
img = imread('eufs_00001.png');

[bboxes, scores] = detect(detector, img);

% Display the detection result
for i = 1:length(scores)
    annotation = sprintf('Confidence = %.1f', scores(i));
    img = insertObjectAnnotation(img, 'rectangle', bboxes(i,:), annotation);
end

figure
imshow(img)

See this function to get row and column indexes from a bounding box.

% For each blob measured by regionprops(), this converts the BoundingBox measurements, which lie 0.5 pixels outside the region,
% into coordinates that lie along integer rows and columns for ease of use in indexing images.
function [yRow1, yRow2, xCol1, xCol2] = BoundingBox2Indexes(props)
try
    xCol1 = 1;
    xCol2 = 1;
    yRow1 = 1;
    yRow2 = 1;
    if isempty(props)
        return;
    end
    if ~isfield(props, 'BoundingBox')
        errorMessage = sprintf('Error in function BoundingBox2Indexes():\nYour regionprops output that you sent to function BoundingBox2Indexes()\ndoes not have a field called BoundingBox.');
        uiwait(errordlg(errorMessage));
        return;
    end
    allBB = vertcat(props.BoundingBox);
    xCol1 = ceil(allBB(:, 1));
    yRow1 = ceil(allBB(:, 2));
    xCol2 = xCol1 + allBB(:, 3) - 1;
    yRow2 = yRow1 + allBB(:, 4) - 1;
catch ME
    % Some error happened if you get here.
    errorMessage = GetErrorMessage(ME); % Get error message with call traceback and file's date.
    WarnUser(errorMessage); % Pop up error message to show user what it is.  Also prints to command window or console window (if program is an executable).
