clear all;
clc;
close all;
[filenameList, pathnameList] = uigetfile(...
    {'*.jpg;*.tif;*.png;*.gif;*.bmp','All Image Files'},'mytitle',...
    'MultiSelect', 'on', ...
'c:/DatasetResultsNew/');
pathname = pathnameList;
for iFile=8:10  % 1:28 %check out here
    
    filename = filenameList{iFile-7};
    filename2 = strrep(filename,pathname);
    fprintf('Processing image %s\n', filename);
im_GroundTruth = imread([pathname,filename]); % object=1; backgroud = 0;
im_GroundTruth(im_GroundTruth>0)=255;
im_segmentaion = im2uint8(imread([pathname,filename2])); % object=1; backgroud = 0;
Conf = confusionmat(im_GroundTruth(:),im_segmentaion(:));
recall = Conf(2,2)/sum(Conf(2,:))*100;
precision = Conf(2,2)/sum(Conf(:,2))*100;
f_measure = 2*recall*precision/(recall+precision);
metricsMatrix(iFile).recall=recall;
metricsMatrix(iFile).precision=precision;
metricsMatrix(iFile).f_measure=f_measure;

i want to read all images from the folder to compare the mask which i created with the given mask to find precision, recall and f-measure. this code will find precision, recall and f-measure and create a matrix for every record
