HI,
Before reading the image (imread), you shoud change directory, where the files are present, as like as below
clc;
close all;
clear;
OutputFolder = 'D:\Datasets\handwritten-signatures\sample_Signature\edited';  % Set as needed [EDITED]
dinfo = dir('D:\Datasets\handwritten-signatures\sample_Signature\genuine\*.png');% image extension
for K = 1 : length(dinfo)
    thisimage = dinfo(K).name;
    cd 'D:\Datasets\handwritten-signatures\sample_Signature\genuine\'
    Img   = imread(thisimage);
    cd ..
    Y     = imshow(Img);
    Gray  = rgb2gray(Img);
    i = imresize(Img, [227, 227], 'bilinear');
    imwrite(i, fullfile(OutputFolder, thisimage));  % [EDITED]
end
