Human face detection is a key technology in face information processing, the speed of which is very important during real-time face detection for input images or input video sequences. This paper presents a novel face window searching algorithm based on evolutionary agent when detecting faces in gray-scale images. It can quickly And the candidate face windows through the evolutionary computation of...
Image segmentation is a valuable approach that performs an object-based rather than a pixel-based analysis of high-resolution remotely sensed imagery. An approach for segmenting the multispectral QuickBird image based on first fundamental form is proposed. The value of multispectral image at a given point can be regarded as N-dimensional vector, and the difference of image values can be defined from...
In this paper, we examine a novel image-filling algorithm to fill the occluded and partial regions of the iris. In iris recognition, these occlusions naturally appear due to eye-lids being partially closed, eye movements and eye-lashes. Additionally, specular reflections arising from the iris-camera illuminator are present and produce occlusion artifacts on the iris region. In the polar representation...
As a critical step in many multimedia applications, shot boundary detection has attracted many research interests in recent years. The most of existing methods measure the similarity among video frames based on its low-level feathers. However, they are sensitive to the change in not only brightness, color, motion of object, but also camera motions and the quality of video. This paper proposes an innovative...
