What are the techniques for face detection on a bitmap?

I'm quite curious about this since it's quite a leap in image processing. In a broad way, how would one do face recognition on a bitmap? Edit: My intention is a brief description on how a face is recognized. Not for comparison. Just how to recognize that there is a face in a bitmap. The Wikipedia article is sparse on algorithm explana...

Delphi Components for Face Identification and Tagging

Are there any good components, free or commercial, available for Delphi (I use Delphi 2009) that will allow me to easily implement face detection and tagging of the faces in photos (i.e. graphics/images)? I need to do something similar to what Google Picasa's Web Albums can do, but from within my application. ...

Face-tracking libraries for Java or Python

Hi, I'm looking for a way to identify faces (not specific people, just where the faces are) and track them as they move across a room. We're trying to measure walking speed for people, and I assumed this would be the easiest way of identifying a person as a person. We'll have a reasonably fast camera for the project, so I can probably...

Robust Face Detection in C/C++?

I'm looking for a robust face detection algorithm/library, preferably in C (C++ is okay too; other languages I can port if necessary). I've used OpenCV's implementation in the past, but I don't think it's invariant to rotation. Doesn't need to be real-time, but it shouldn't be horrendously slow either (maybe one or two seconds per photo ...

Face detection + Image morphing

Hello, I am looking to create a site like photofunia.com where basically you can apply a large number of effects to an image. I am wondering if someone can guide me in the right direction as to the technology which must be used to achieve the same? Also, are there any open-source commandline utilities available to create such images? I...

How to use the VGA camera as a optical sensor?

Hi, I am designing an information kiosk which incorporates a mobile phone hidden inside the kiosk. I wonder whether it would be possible to use the VGA camera of the phone as a sensor to detect when somebody is standing in front of the kiosk. Which SW components (e.g. Java, APIs, bluetooth stack etc) would be required for a code to use...

Face detection in java

Can anyone recommend a decent java library for face detection (recognition not required, just detection). The library would preferably be pure java (e.g. no dependencies on other native libs, DLLs or such). Platforms: Linux is a must; OS X and windows are very nice to have. Performance isn't a big deal, can be slow, it's for server offli...

Facial recognition/detection PHP or software for photo and video galleries

I have a very large photo gallery with thousands of similar people, objects, locations, things. The majority of the people in the photos have their own user accounts and avatar photos to match. There are also logical short lists of people potentially in the photo based on additional data available for each photo. I allow users to tag pho...

How can I detect faces using Ruby?

Can anyone tell me how to detect faces in a static picture using Ruby or Javascript? ...

Viola-Jones' face detection claims 180k features

I've been implementing an adaptation of Viola-Jones' face detection algorithm. The technique relies upon placing a subframe of 24x24 pixels within an image, and subsequently placing rectangular features inside it in every position with every size possible. These features can consist of two, three or four rectangles. The following exampl...

Face Recognition for classifying digital photos?

I like to mess around with AI and wanted to try my hand at face recognition the first step is to find the faces in the photographs. How is this usually done? Do you use convolution of a sample image/images or statistics based methods? How do you find the bounding box for the face? My goal is to classify the pictures of my kids from a...

face detection Asp.net c#

Hello, i have implement asp.net web application in this application i add face detection functionality. i have found entire google but did not get solution. If you have any idea about this solution,please let me know. Thanks in advance ...

Adaboost algorithm and its usage in face detection

I am trying to understand Adaboost algorithm but i have some troubles. After reading about Adaboost i realized that it is a classification algorithm(somehow like neural network). But i could not know how the weak classifiers are chosen (i think they are haar-like features for face detection) and how finally the H result which is the fin...

What preprocessing image techniques should I take in consideration before applying OpenCV's Viola-Jones method for face recognition ?

Hello, I am working for a project at school regarding face recognition, based on a technique described by Viola and Jones 2001/2004. I've read that the OpenCV has an implementation of this algorithm, and it works very good. I was wondering if you have any advices regarding what techniques (pre-processing) to apply to the images befor...

OpenCV to JNI how to make it work?

I am tring to use opencv and java for face detection, and in that pursit i found this "JNI2OPENCV" file....but i am confused on how to make it work, can anyone help me? http://img519.imageshack.us/img519/4803/askaj.jpg and the following is the FaceDetection.java class JNIOpenCV { static { System.loadLibrary("JNI2OpenCV");...

Is there any fast library(s) for finding human eyes and mouth in Flash? (Actionscript)

So I have real time video stream. With 1 (one) person on It . It Is Black and White, I need to be able to capture this persons eyes and mouth (direction (at least X,Y), state (at least opened or closed) ) So Is there any fast library(s) for finding human eyes and mouth in Flash in such case? (pure Actionscript or Haxe\Java\C++\C port in...

Face Detection Neural Network Training Data (databases, number of faces etc)

Hey, I'm creating a face detection program using neural networks, and looking for some reliable training sets. I'm aware there's various sets around the web, but I've not idea how good they are. Any ideas where to start? Thanks. ...

AI Techniques for Face Detection

Can anyone all the different techniques used in face detection? Techhniques like neural networks, support vector machines, eigenfaces, etc. What others are there? Thanks. ...

Activation Function, Initializer function, etc, effects on neural networks for face detection

There's various activation functions: sigmoid, tanh, etc. And there's also a few initializer functions: Nguyen and Widrow, random, normalized, constant, zero, etc. So do these have much effect on the outcome of a neural network specialising in face detection? Right now I'm using the Tanh activation function and just randomising all th...

Neural network to output non-binary values?

I've been looking at face detection lately, and a lot of the literature states their outputs have a range. How is this possible? I've created my own network and it only seems to be outputting either -1 or 1. Is this because I'm using the Tanh activation function? I want the values to output from, say, 0 to 1 in a range, rather than a ...
