Tracking red color objects using matlab

This program just tracks all red color objects and draws a bounding box around them.

Description

This program just tracks all red color objects and draws a bounding box around them. This works on the difference between frames concept. Every frame in the video is returned as an rgb image on which we can do image processing stuff.

• MATLAB release: MATLAB 7.7 (R2008b)

wow!!really that was so simple.can u tell me where u learned this stuff.it will be really helpful

[A. Bhargav Anand]

@akash Dude, download the code, I have documented the whole code. Just go through it, try reading the documentation of every function i have used. And yeah, where did I get this stuff, GOOGLE it man !!!

hi dude can u tell me how i can detect other colour..
i mean where i can change the code so i can do that thing...
thanks...

[ika]

can u tell me how to make tracking object if i want track motion object and give annotation from start point untilthe object stop moving,so i can track from fisrt position, for example tracking with line???

thanks before....

[A. Bhargav Anand]

@hiren, ika- sorry guys, ive been little busy these dayz, neways ill definitly get back to you guys with an answer. As of now this program was written only to detect the standard colors i.e. Red, Green & Blue colors. I was thinking to extend the whole program by adding a graphical interface and generalizing the whole tracking process.

@akash- you get lotz of stuff on internet dude. juss google about object tracking or motion tracking. Look the documentation of the image processing & video processing toolbox in matlab. Use the matlab help and go through the documentation of important functions that will be helpful. Thas enough fr mastering fundas !!! :)

Updated the code guys. Also uploaded a video.

you are wonderful !!!
Thank you alot

Thanks man :)

The speed of your code can be greatly improved if u can keep preview open in background.Also try to replace getsnapshot with peekdata (dont know to what extent it is possible)to reduce execution time(this may require manual triggering)

[Winston Larson]

I had this working like a dream on Windows (this is a wonderful piece of software), but it seems to have trouble on a Mac. The video doesn't move fluidly, but rather captures just a couple of frames. Does anyone have the same issues, or advice? I'm admittedly new to Mac... Thanks!

I think it would be better if you use the conversion rgb to hsi, and determine the red color with hue, but it is a nice algorithm, and you help me a lot to know how to use my laptop camera.

[Atif Anwer]

Brilliant Job Done! Really helpful in using this as a start for my Vision project :)

[Muhammad usman khan]

hey please tell me to initialize webcam in MATLAB... im new in MATLAB.. what i have to write in your code to run it...
i thnk its cam name n resolution etc.. please give me example of correct syntax and where to read the name of camera and resolution...

Dude, my ML tells me that an error occurred " Error: File: redObjectTrack.m Line: 2 Column: 2
An array for multiple LHS assignment cannot contain character string." i think its related to the format of my camera : YCbCr422_640x480 does your program run with this format

i'm getting errors from the getcamerainfo function

Error in ==> getCameraInfo at 4
camera_id = camera_info.DeviceInfo.DeviceID(end);

Error in ==> redObjectTrack at 2
[camera_name, camera_id, format] = getCameraInfo(a);

running r2010a 64 bit in windows 7

how might i remedy these errors

[nishant]

outstanding

Hey Dude if you teach me create red light camera using M-file ? pleasee

[Boo]

 

[TEJASVI DANDONA]

Hi..Cud u pl tell me how to-
1) track colours other than red.
2) set the threshold such that the object in the front is tracked and not any other object in the back.
Thnx...

[Mohamad Faiz]

Hi dude, do you know how to track red color using IP camera?

[Mr Smart]

 

[Peter Russo]

Awesome, thanks a lot! I've been trying to make my own that uses just the intensity of the grayscale image, which is giving me lots of problems. By just picking a color, like red, it should be a lot easier. Thanks

[Mahdy Jadaliha]

Great job. Thank you for sharing.

[elias argaw]

please help
i try your code but i got the below message how i can fix it

??? Undefined function or method 'getCameraInfo'
for input arguments of type 'struct'.
