Ido Nissenboim, Daniel Keren, Michael Werman
2008 2008 IEEE International Conference on Signal Image Technology and Internet Based Systems  
We propose a "quick rejection" paradigm which is applied to face detection.  ...  The resulting features are easy to find, extremely fast to apply, and achieve a good detection rate.  ...  Next we define the features and explain how they are derived and used. We shall hereafter speak of face detection, but the method can be applied to other image classes as well.  ...

Automatic local Gabor Features extraction for face recognition [article]

Yousra Ben Jemaa, Sana Khanfir
2009 arXiv   pre-print
A new algorithm is proposed in order to detect automatically face features (eyes, mouth and nose) and extract their correspondent geometrical points.  ...  We compare the two types of features used for recognition: geometric distances and Gabor coefficients which can be used either independently or jointly.  ...  We use the two techniques; we first locate the feature points and then apply Gabor filters in each point in order to extract a set of Gabor wavelet coefficients.  ...

Comparison of two different approaches for multiple face detection in color images
IJIREEICE - Electrical, Electronics, Instrumentation and Control

In this paper, the performance comparison has been made of two different algorithms for multiple face detection in color images.  ...  Human face detection has become a major field of interest in current research because there is no deterministic algorithm to find multiple faces in a given image.  ...  In second phase skin color pixel detection is used to extract all the entire skin color pixels from the image. Once they are extracted Viola Jones is applied to detect face.  ...

A Novel Approach to Face Detection and Feature Extraction using Image Processing

Sunny Shah
2017 International Journal for Research in Applied Science and Engineering Technology  
This paper describes a human face detection and feature extraction based on skin color segmentation and geometry of face. The system consists of several stages.  ...  Features are extracted using the size and the relative position. If system fails to find any of single feature in possible face block, it rejects face block.  ...  Here we have combined RGB, Normalized RGB, and HSV color spaces to detect ski pixels.  ...

Enhanced weakly trained frontal face detector for surveillance purposes

Wael Louis, K. N. Plataniotis, Yong Man Ro
2010 International Conference on Fuzzy Systems  
This paper claims that only a subset of the total number of features conserves the major power to detect faces; hence, this subset is capable to detect faces with high detection rate.  ...  A pre-processing stage of skin-tone detection is applied to reduce the false positive rate. The detector is examined on real-life lowresolution surveillance sequence.  ...  These features proved the capability to extract face discriminative features; however, the number of features is limited to the number of pixels, so two classification schemes were required.  ...
