A Symmetry Based Face Detection Technique
نویسندگان
چکیده
In this paper a symmetry based face detection technique is proposed. Here symmetry of the human face is used to quickly locate the human faces from an image. At first sobel edge detection operator is applied to get the edge image from the original image. In order to measure total number of symmetrical points present in an image window, a newly proposed point symmetry based distance is used. Kd-tree based search is used to reduce the complexity of computing point symmetry based distance. The window having the maximum number of symmetrical pairs is considered having the candidate face region. The effectiveness of the proposed method is demonstrated in detecting faces from six different images.

A Novel Face Detection Method Based on Over-complete Incoherent Dictionary Learning
In this paper, face detection problem is considered using the concepts of compressive sensing technique. This technique includes dictionary learning procedure and sparse coding method to represent the structural content of input images. In the proposed method, dictionaries are learned in such a way that the trained models have the least degree of coherence to each other. The novelty of the prop...
متن کاملFrontal View Face Detection
This paper presents a symmetry measurement based on the correlation coeecient. This symmetry measurement is used to locate the center line of faces, and afterward, to decide whether the face view is frontal or not. A 483-face image database obtained from the U. S. Army was used to test the algorithm. Though the performance of the algorithm is limeted to 87%, this is due to the wide range of var...
متن کاملEmploying Symmetric Subsets for Identifying Asymmetry of Human Skulls
This paper describes a technique for analyzing shapes with potential symmetry employing symmetric subsets. The proposed technique assumes that the shapes interested have potential bilateral symmetry. The notion of potential symmetry is given to those shapes with approximate or original symmetry. As respective examples, we can imagine a human face and a partial broken vase. Although their symmet...

The face Detection methodsis used in order to provide security. The mentioned methods problems are that it cannot be categorized because of the great differences and varieties in the face of individuals. In this paper, face Detection methods has been presented for overcoming upon these problems based on skin color datum. The researcher gathered a face database of 30 individuals consisting of ov...
متن کاملShape Matching Based on Fully Automatic Face Detection on Triangular Meshes
This paper tackles a particular shape matching problem: given a data base of shapes (described as triangular meshes), we search for all shapes which describe a human. We do so by applying a 3D face detection approach on the mesh which consists of three steps: first, a local symmetry value is computed for each vertex. Then, the symmetry values in a certain neighborhood of each vertex are analyze...
