face recognition+image

narendar · 06-16-2009, 08:29 AM

Hello All,

Can we recognize the face part(skin) of an image with the objC??

I dont have much idea about this.Can any one provide the related information about this.

Thanks,
Naren

Is this a serious question? Have you ever worked in ANY programming language where face recognition is provided by the language? If so, I'm curious to know what language(s).

Hi Kalimba,
Would you please like to clear my doubts about How face detection works in digital camera if that is not done through a programming language. Is it done by some hardware or lens or anything but not by programming. I think in camera's some 3D environment is created and the some special points are detected like nose, ears, forehead, chin and then face detection has been done. I hope it is like that but you are more experienced than i am so you might be right , there might be some hardware is used.
Thanks
Naren

What he meant is that you have to do the algorithm, is not something that comes with the language. Face recognition is a pretty complicated topic and is something that probably can't be explained in a forum, there are books that focus on that topic alone.

You have to separate between programming language and a framework or library.

If you took some advanced class in Image Processing, or something similar, you should be able to find the theory behind it, and maybe practical project, but I really doubt they're using objective-c as an implementation.

I think some people had done this with Matlab, you just need to recreate the algorithm in C, or maybe objective-c directly.

Yes you are right,
In matLab i have seen it,
and one of my friend did it as a final year Project
Face recognizing (MatLab).
so here was my doubt when kalimba said that have you ever worked on a programming language where you can do it by programming and is it a serious question. so i went into a doubt and i asked him to clear it. as far as i know it is possible by programming only but what matters is your api's and language. if it is not provided by iphone than we have to do it by own.

Because the OP were not saying it in the "right way"

Face Recognition requires complex math, so most people could do it easier with Matlab, because it has all of those math tools already available, doing this in C with Obj-C requires a lot of work and patience.

It was not me dear,
I am not the owner of this post,
I was just reading the post that's it.
I checked the answer for that and replied.
might be the question posted is not clear to all,
and a bit confusing . Narendar please be clear on your question and ask again now there are many senior members related to this topic. make them clear about your queries and might they show you some direction and you get what you want.

Hello

Thanks for your discussion on this topic.

Basically I need to modify a image and need to get the tanning effect for that.

I need to get the defferent effects for the image as per the tanning period I set(Ex: If set tanning period of 15sec the face part of the image should make some dark and by increasing the period the intesity of the darkness should increase ans so on).

I have seen one of the apps modifying only the nose part an image , how they recognising the only the nose part ??(face detection in the image).

I have read that with OpenCV framework we can recognise the face(skin) in a image, but did not get how to implement that.

I think now it is clear , what I want to do.

Any one have idea about this??

Thanks,
Narendar

Thanks , I will look into that
