Music Player with Hand Gesture Control using Neural Network

Hello guys, I have already posted an article on hand gesture recognition using neural network,if you have not see it then please go through it first.Well,here is the Link 

So,using the previous implementation I am now going to show you how you can built a Music Player that will be controlled by hand gestures.That means there will be a separate predefined gesture for performing every individual task that will be performed on the player.

That means there will be an unique gesture for Play,another for pause and so on.

So here are the steps using which you can built it easily :

1. I hope you are all familiar with Matlab GUI,if not then please see this Link 

2. Now here I am not going to briefly explain how to play and pause music in matlab,here my main focus is to tell you how can you control this using hand gestures.

Still,if any one has any problem in building the music player he or she can tell his or her problem through comment,then I will post the code for that later.

3. For example lets assume we use the following gesture for play action.

Then we have to get at least 5-10 pic like this and save it into a folder.

4.  Now train the network with the sample picture,so that when ever any similar gesture is detected during testing,then system would perform some task.

For code reference,please visit this link below :

Gesture Recognition using Neural Network

5.Now the point is where to insert the code. Well for every recognition system we go for a threshold value to determine whether it is the desired result.In the previous Hand gesture recognition system post also I have done the same in the end.

So insert the desired music player action code within that MATCH_FOUND code block.
like this,

if(PLAY_IMG_MATCH_FOUND==TRUE)
{
  //Music player play code
}

Similarly if you want to perform any hard ware related task then just go to this link  and insert the code in the same block as I mentioned before.

Just for example,I have shown this one example PLAY action with this sample images and one gesture.

You can use different gestures for performing different task like PAUSE,STOP etc.

There are lot more things to do with this project...try it yourself, and please let me know about your new works...best of luck...thanks for visiting,have lots of fun :)

Gesture Recognition using Neural Network in MATLAB Code

Hi guys,many people were requesting for gesture recognition code so here it is ...
Well for any recognition system there are some simple common states what we also followed here they are:

1. First you have to have data set.Which you have to prepare or download from any website according to your demand.Like you want to want to recognize an alphabet 'O'.Then you have to provide particular data set for 'O'.

Like this :

Okey this is only one picture but I recommend at least 5 pictures you have to give to recognize a gesture.

2. Now give matlab access to the data sets providing particular path of the folder on your system,it is better to make different folder for different alphabet sample.

3. Now you have to train the network.I will show you how to do it in later part.It is the most important part,here you are making your network understand that " ANY IMAGE LIKE-THIS IS ALPHABET 'O' "

4.Here you need to provide an algorithm that will set such a threshold value that will decide whether the test image is 'O' or NOT.

5.Now you need some more sample of 'O' to test the network whether it is coming fine.

6.Well that is it. I will give you the sample code in my next post so that it will be easy for you to implement.

Silent Password Creation using matlab

Here we are going to create silent password.We can do this using both from a video file or from live streaming.The main thing is that he camera should focus on the lip.It should track the lip movement.The key idea is that we are going to take a threshold value,using that particular value we are going to check whether the password is wrong or right.We will track the lip movement,if the movement is beyond threshold then wrong password otherwise right.

Well here are the steps we need to do to create a silent password with matlab :

1.Take video of lip movement or record using webcam.

2.Now use a detection algorithm algorithm from here
(Note : if you are using live detection you need to track the motion using another method,that code is also available in this blog,here is the link.

3.Now what you need to do is that you need to set the threshold value.

Threshold value :

Now the threshold value can be set or generated in many ways.I have done it in one way what i am going to tell you but you can follow different approach. 

i.I have calculated the no of frames between one lip touching frame to the next one.In live streaming case the threshold should be given a bit large for less errors.

ii..For my case the calculated frame no is the threshold.If you find any better approach please let me know through comment.

4.So once the threshold is calculated your prog is okk.

5.Now simple calculation if detected result is beyond threshold then rejected otherwise accepted.

Play Computer games with hand gesture recognition using Matlab

To do this experiment,just you need an webcam and matlab2012a or 2012b

Now we are gonna do live motion detection,the below live detection code is not written by me,i got it from this link http://arindambose.webs.com/htmls/Motion%20Detection%20in%20LIVE%20Video.html

vidDevice = imaq.VideoDevice('winvideo', 1, 'YUY2_640x480', ...
'ROI', [1 1 640 480], ...
'ReturnedColorSpace', 'rgb');
optical = vision.OpticalFlow('OutputValue', 'Horizontal and vertical components in complex form');

maxWidth = imaqhwinfo(vidDevice,'MaxWidth');
maxHeight = imaqhwinfo(vidDevice,'MaxHeight');
shapes = vision.ShapeInserter;
shapes.Shape = 'Lines';
shapes.BorderColor = 'Custom';
shapes.CustomBorderColor = [255 0 0];
r = 1:5:maxHeight;
c = 1:5:maxWidth;
[Y, X] = meshgrid(c,r);

hVideoIn = vision.VideoPlayer;
hVideoIn.Name = 'Original Video';
hVideoIn.Position = [30 100 640 480];
hVideoOut = vision.VideoPlayer;
hVideoOut.Name = 'Motion Detected Video';
hVideoOut.Position = [700 100 640 480];

nFrames = 0;
while (nFrames < Inf)
rgbData = step(vidDevice);
optFlow = step(optical,rgb2gray(rgbData));
optFlow_DS = optFlow(r, c);
H = imag(optFlow_DS)*50;
V = real(optFlow_DS)*50;
lines = [Y(:)'; X(:)'; Y(:)'+V(:)'; X(:)'+H(:)'];
rgb_Out = step(shapes, rgbData, lines');
step(hVideoIn, rgbData);
step(hVideoOut, rgb_Out);
nFrames = nFrames + 1;
end
release(hVideoOut);
release(hVideoIn);release(vidDevice);

But after this Ive changed this a little bit and  made a different thing,hope you like it.

So the code i got from the above link,well im pasting it here,

Now again use the redbox around the motion

rectangle('Position',cen,'EdgeColor','r','LineWidth',5);

Now perform a mouse click operation whenever a redbox appears in the video,get the code here

So,this is how your computer player will fire or do some other stuff as per game settings

And move the mouse pointer as per box location,code is Here

By this your player will switch it's view,

Now after doing all this,

1.Run your matlab code

2.Minimize the video stream

3.Run the game you want to play

I've tried this with some popular games,like counter strike,IGI 

Well this is a very basic idea,you can implement it further....you can also add some keyboard operation for performing other tasks,Keyboard Code here

try it it will definitely work... Thank u

Vehicle Counting System in Matlab

1. Input a video of vehicles ex. test.avi
2. Now extract the frames and save in a specific folder
    Get the code here, one of my previous post
3. Detect the motion of the vehicle in the video
    Get the code here

Now if everything has gone alright,we can begin.

We just make very simple changes in the previous code to make the thing work perfectly.

Step 1 : Watch the redbox around the moving object.Now insert this code in there

             rectangle('Position',cen,'EdgeColor','r','LineWidth',5);
     
             Here 'cen' is the centroid

Step 2: Now the most important step,insert this code after that

        txt=text(no, strcat('car: ', num2str(round(no))));
        set(txt, 'FontName', 'Arial', 'FontWeight', 'bold', 'FontSize', 12, 'Color', 'black');

It will display the number of cars. 'no' is a variable which is set to '0' at first.But when ever a motion is detected in the video 'no' will be incremented by 1,that is how we get the vehicle count.

But the basic problem what you will face in this method that is,here we are considering frame after frame,so the 'no' variable gets incremented each time,but thats not what we want,we want the actual count,so we are gonna need a FLAG variable which indicates if 'no' is incremented by 1 for a particular vehicle then it wont increment for the specific one again.

like this,
FLAG=0;
if FLAG==0
   no=no+1;
   flag=1;
   frame=frame+1;
end
else
   frame=frame+1;
end

So now it is done,Thank You :)

If you dont know how create basic matlab GUI then you can see my previous post :

Building GUI with Matlab

Step 1 : I have made a very simple interface,drawn just a button  and an axes

Step 2 : Now open the GUI .m file by clicking view and then m-file editor

Step 3: Now paste the above code in the pushbutton_callback function and save

Step 4: Now run the code,press play button,then it should ask for the image folder path,write the path press          enter it will show the images

Building GUI with Matlab

1. Type 'guide' on the console and press enter



2. Now select a guide template and mark 'save on start up as' option then change the name,ex. test.fig
then press ok.

3. A screen will appear like this one...



4. Now you can draw button,use axis for showing images or videos,and make your own GUI.

5. To edit the matlab code do this,



6. Copy the matlab code what you want to execute after pressing a button within that particular button function

7. Then run your code pressing 'f5' it should show the GUI you built.
