thermal image processing, the maximum temperature area isolation

Hello, I have problem with matlab code. I have JPG image file and I need that image will be convert to mat file. The second step is the temperature value research. In the face area i need to found the temperature which is bigger than indicates significance ( for ex. 30 C) and market that area in the picture. I try to write some code but I have only that:

clear all; close all; clc;

addpath(genpath(pwd));

Thermo = 'C:\Users\Dovile\Desktop\bakalauras\MatLab\';

if ~isdir(Thermo)

    errorMessage = sprintf('Error: The following folder does not exist:\n%s', Thermo);

    uiwait(warndlg(errorMessage));

    return;
end

filePattern = fullfile(Thermo, '*.jpg');

jpegFiles = dir(filePattern);

result = cell(1,100);

for k = 1:length(jpegFiles)

    maxvalue = 0;

    maxvalue_g = 255;

    maxmalue_b = 255;

    max_x = 0;

    max_y = 0;

    baseFileName = jpegFiles(k).name;

    fullFileName = fullfile(Thermo, baseFileName);

    fprintf(1, 'Now reading %s\n', fullFileName);

    imageArray= imread(fullFileName);
    [x,y,z]=size(imageArray);
    I1=rgb2gray(imageArray);
    [x,y,z]=size(I1);
    for j = 1:x
        for i = 1:y
            if I1(j,i) > maxvalue
                maxvalue = I1(j,i);
                max_x = j;
                max_y = i;
            end
            if imageArray(j,i,1) > 150
                imageArray(j,i,:) = [255,0,0];               
            end
        end
    end
    imageArray(max_x,max_y,:) = [0,0,0];  
    %I1=rgb2gray(imageArray); figure,imshow(I1); title('gray converted Image')
    colormap('default');   % set colormap
    result{k} = imageArray;
    figure,imagesc(result{k});        % draw image and scale colormap to values range
    hold on;
    plot(max_x,max_y,'g.','MarkerSize',20)
    title(fullFileName)
    colorbar;
end
save kita.mat result;
load kita.mat
%image(k)
