Artificial intelligence digital signal image processing demonstration system

This article is an artificial intelligence digital signal image processing demonstration system based on MATLAB. This design has a rich GUI human-computer interaction interface. The design of the system implements three demonstration modules, which are common signal analysis and display, and then image filter Finally, the digital signal processing simulation system realizes the display function of 13 common signals, 6 image enhancement functions, 4 image adding noise functions, 3 image filtering functions, signal superposition, sampling, recovery, Process demonstration functions such as frequency domain display. The design is not very good, please forgive me! .....

The following is the main interface of the system, and then show part of the code,

 

function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
close;
signalprocess;

Analysis of common digital signals shows that, 

 

%正弦信号
y=A*sin(w*t+p);
plot(t,y,'linewidth',line_width);
title('sin');

 

image filter design,

‘’

function pushbutton4_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton5 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global image;
axes(handles.axes);
imhist(image);

Digital signal image processing simulation,

t = -3*pi:0.01:3*pi;
y = A1*sin(w1*t+p1)+A2*sin(w2*t+p2)+A3*sin(w3*t+p3);
axes(handles.axes2);
plot(t,y,'k-' ,'linewidth',1);
axis([-3*pi,3*pi,-A2-A1-A3-0.2,A2+A1+A3+0.2]);
