function chkSaltPepper_Callback(hObject, eventdata, handles)
x = get(handles.TxtNoiseDensity,'String');
d = get(handles.TxtNoiseDensity,'Value');
if isempty(x)
errordlg('Error:Please enter noise density');
else
noiseImage = imnoise(noiseImage,'salt & pepper',d);
function TxtNoiseDensity_Callback(hObject, eventdata, handles)
input = str2double(get(hObject,'String'));
