We present the Spherical Demons algorithm for registering two spherical images. By exploiting spherical vector spline interpolation theory, we show that a large class of regularizors for the modified Demons objective function can be efficiently approximated on the sphere using iterative smoothing. Based on one parameter subgroups of diffeomorphisms, the resulting registration is diffeomorphic and...
As observed, the described approach to computer-aided error detection in printed matter proves itself to be exact and reliable. Our prototype printing error detection computer program has also undergone extreme testing in an industrial environment. The problem of excessive detection duration will have to be solved by an optimization of the registration and interpolation procedures. When considering...
How to get high-resolution face image from low-resolution video sequence with time-saving demand is an important problem. In this paper, a new framework is described to extract high-resolution face image from video sequence. Firstly, the real-time face detection based on AdaBoost algorithm and Haar like feature is implemented. The detected face area is segmented from the background to form a face...
