This paper describes the concept of intelligent building integration system. Taking ez IBS as the platform, it designs the overall structure of a large-scale intelligent building system integration, and also makes a detailed analysis of the key technology and innovative design ideas of architecture design and implementation of intelligent integrated system, so as to realize the sharing of information,...
3D face modeling in computer graphics and virtual reality technology is a hot of research. In this paper, we get the original three-dimensional face data through optical scanners. Due to a variety constraints of conditions (light, face of the rough parts), there are many empty parts of the face. In this paper, we use Hermite cubic spline interpolation algorithm to repair three-dimensional facial model...
In the paper an face location and eye detection method is proposed based on active infrared source system, which is to solve the problems of pupil threshold segmentation according to from coarse and fine strategy. This method use bright pupil and dark pupil difference scheme. Firstly, we collect a lot of dark images to train classifiers make use of Haar features, boosting them to be a strong classifiers...
Facial expression recognition is necessary for designing any human-machine interfaces. A novel facial expression recognition method with wavelet packet decomposition and neural network ensemble is proposed in this paper. Firstly, the facial expression images are converted by wavelet packet decomposition method into many decomposed regions. Secondly, single BP neural networks are trained by the K-L...
Bayesian Networks (BN) are an effective method to recognize facial action units (AUs) combinations, which is a key issue of AUs recognition. Learning BN structures from data is NP-hard. Greedy search algorithm is a practical approach to learn BN from data, but it is liable to get stuck at a local maximum. In this paper, an improved greedy search algorithm is proposed in order to deal with the above-mentioned...
In this paper, we theoretically analyze the limitation of the Quotient Image (QI) method proposed by Shashua and present a new way to compute the quotient image. Based on the observation that nine basis point light sources can represent almost arbitrary lighting conditions for face recognition application, we use the corresponding nine basis images which are all real images to span the image space...
A feature fusion algorithm with application to facial expression recognition is presented. Firstly, the brows, eyes and mouth areas are segmented from the facial expression images, and are computed with Higher-order Local Auto-Correlation (HLAC) method, and the Weighted Principal Component Analysis (WPCA) is used to reduce dimensions secondly, in which the weights values are obtained according to...
Facial action units (AUs) recognition is a challenging problem with many applications and is rapidly becoming an area of intense interest in research field of machine vision. Nonadditive AU combinations in which the appearance of the constituent AUs does change greatly increase the difficulties of AU recognition. Most AUs recognition methods treated each AU combination as a new AU. However, these...
