hai friends..i want to do a real-time logo detection and recognition system using matlab but i don't no how to create that..if someone can tell the solution,i really appreciate that..thanks

I'm not sure why you are posting here.  If you want to do something in LabVIEW or CVI, you should post here.  If you want to do it in matlab, you should probably find a matlab board somewhere.

Now, if I was to do this in LabVIEW, I would just train a template and use pattern matching.

thank u 2 bruce..i just post this question at this website.. i just wanna get some idea 4 my project ..

[BruceAmmons]

It really depends on your project.  Are there multiple logos you are trying to recognize, or just find the one logo?  Are the logos going to be different sizes and introduce scaling issues?

If it is always the same logo and always the same size, standard pattern matching would probably work well.  I would also consider geometric pattern matching, but that depends more on the logo.

my project is about to detect and recognise a 'halal's logo..it means use real-time concept. we take pictures using webcam and the system will display that the logo is legal or not. at this time, i just  want to try 2 or 3 different types of 'halal's logo..i have sent an emel to matlab@yahoogroups but no reply..the size of the logo is same but a bit different at the design of the logo.

As Bruce mentioned, pattern matching or geometric matching should work for your application as long as the logo has distinct features that can be recognized.

You may also use OCR to detect characters of the word "Halal".
