چکیده
Fiibding human f a c e s automatically in a scene is a d i f f i c u l t yet significant problem. T h i s i s the first important step in a f u l l y automatic human f a c e recogiiition system. In this pap,er w e p ~ ~ p o ~ e a new method lo locate human f a c e s in a complex background. T h i s Jystem utilizes a hierarchical know ledge-based method and consists of three levels. T h e higher t w o levels are based on mosciic images at different resolutions. In the l o w w level, an improved edge detection method is p,roposed. I n this TeMaTCh w e have solved the problem of scale and m a d e the system more practical , 90 that the system caii locate unknown human faces spanning a w i d e range of sizes in a complex black-white picture.

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard
Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملImproved AdaBoost Algorithm for Robust Real-Time Multi-face Detection
Face detection is the basis for research topics such as face recognition, facial expression recognition and face attribute analysis and it plays a crucial role in the field of computer vision. Traditional methods are difficult to meet the needs of robust real-time multi face detection because of some influencing factors such as head pose, image scene, illumination condition and so on. In this p...

The human facial recognition is the base for all facial processing systems. In this work a basicmethod is presented for the reduction of detection time in fixed image with different color levels.The proposed method is the simplest approach in face spatial localization, since it doesn’trequire the dynamics of images and information of the color of skin in image background. Inaddition, to do face...
متن کاملFace detection on distorted images using perceptual quality-aware features
We quantify the degradation in performance of a popular and effective face detector when human–perceived image quality is degraded by distortions due to additive white gaussian noise, gaussian blur or JPEG compression. It is observed that, within a certain range of perceived image quality, a modest increase in image quality can drastically improve face detection performance. These results can b...
متن کاملHuman Face Detection and Tracking using Skin Color Modeling and Connected Component Operators
Face Recognition (FR) systems are increasingly gaining more importance. Face detection and tracking in a complex scene forms the first step in building a practical FR system. In this paper, a method to detect and track human faces in color image sequences is described. Skin color classification and morphological segmentation is used to detect face(s) in the first frame. These detected faces are...
متن کاملTraffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
