两篇人脸检测的英文论文，是花钱买的哦，英文描述中是一篇文章的英文摘要！-Face and facial feature detection plays an important role in various applications such as human computer interaction, video surveillance,

face tracking, and face recognition. Efficient face and facial feature detection algorithms are required for applying to those tasks.

This paper presents the algorithms for all types of face images in the presence of several image conditions. There are two main stages. In

the first stage, the faces are detected from an original image by using Canny edge detection and our proposed average face templates.

Second, a proposed neural visual model (NVM) is used to recognize all possibilities of facial feature positions. Input parameters are

obtained from the positions of facial features and the face characteristics that are low sensitive to intensity change. Finally, to improve

the results, image dilation is applied for removing some irrelevant regions. Additionally, the algorithms can be extended to rotational

invariance problem by using Radon tran
