Signal fast sinc-interpolation by means of FFT 1.1 Digital signal/image geometrical transformations and signal resampling The principle of image geometrical transformation is illustrated in Fig. 1. From this figure one can see that for the transformation digital signal/image resampling (geometrical

A number of techniques have been proposed for flying through scenes by redisplaying previously rendered or digitized views. Techniques have also been proposed for interpolating between views by warping input images, using depth information or correspondences between multiple images. In this paper

In this paper we present an efficient image based rendering system that renders multiple frames per second on a PC. Our method performs warping from an intermediate representation called a layered depth image (LDI). An LDI is a view of the scene from a single input camera view, but with multiple

systematic filter selection scheme which is based on reconstruction of the input image from the filtered images. Texture features are obtained by subjecting each (selected) filtered image to a nonlinear transformation and computing a measure of “energy ” in a window around each pixel. An unsupervised square

Morphable face models constitute a unifying framework for the analysis and synthesis of images. In the field of Computer Graphics, they are applied to synthesize photo-realistic animation of face images; in the domain of Computer Vision, they are used in face recognition applications compen

chosen as a seed, and the remaining steps of the recursive cluster detection are shown in Figs. 2(c)-(i). The final transmitted linking code string of coding from this cluster is ISSI SII I SI SII SI III.

The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory

is important for problems such as optical flow or image restoration that have a large label set. A second technique makes it possible to obtain good results with a small fixed number of message passing iterations, independent of the size of the input images. Taken together these techniques speed up
