% --- Executes on button press in uploadimage.
function uploadimage_Callback(hObject, eventdata, handles)
%% to import the image into the matlab
global a im2
[filename, pathname]=uigetfile('*.*', 'Pick a MATLAB code file');
filename=strcat(pathname,filename);
a=imread(filename);
a=im2double(a);
im2 = a;
axes(handles.axes1);
imshow(a)
title('\fontsize{20}\color[rgb]{0.996, 0.592, 0.0}Kidney Ultrasound')
% --- Executes on button press in preprocessedimage.
function preprocessedimage_Callback(hObject, eventdata, handles)
global a
axes(handles.axes2);
%% change it into gray scale image
b=rgb2gray(a);
%% make the image into binary image
impixelinfo;
c=b>20;
%% to fill the holes
d=imfill(c,'holes');
%% remove some lighting remove the unwanted things in the image
e=bwareaopen(d,1000);
PreprocessedImage=uint8(double(a).*repmat(e,[1 1 3]));
imshow(a);
title('\fontsize{20}\color[rgb]{0.996, 0.592, 0.0}Preprocessed Image')
