A Vector-based Representation for Image Warping
A method for image analysis, representation and re-synthesis is introduced. Unlike other schemes it is not pixel based but rather represents a picture as vector data, from which an altered version of the original image can be rendered. Representing an image as vector data allows performing operations such as zooming, retouching or colourising, avoiding common problems associated with pixel imag...
متن کاملImage-Based Rendering using Image Warping
In this report, I present a complete image-based rendering system. This includes the derivation of a mapping function from first principles, an algorithm for determining the visibility of these mapped points in the resulting image, and a method for reconstructing a continuous image from these mapped points. I refer to this type of mapping function as image warping, because it processes the elem...
متن کاملWarping for image stabilisation
Introduction and overview With a see-through augmented reality (AR) display the image in the display should be updated within a few milliseconds after a head movement of the observer, in order to maintain the virtual objects at a stable location in the visible world. In other words, the virtual camera has to mimic the head movements of the observer as close as possible. Allowed lags are in the ...
متن کاملWavelet Based Image Compression Using Sparse Representation and Vector Quantization
Ordinary images, as well as most natural and manmade signals, are compressible and can, therefore, be well represented in a domain in which the signal is sparse. Sparse signal representations have found use in a large number of applications including image compression. Inspired by recent theoretical advances in sparse representation, we propose an image compression using wavelet, sparse represe...
متن کاملImage Warping
This note introduces the concept of image warping and treats the special case of Euclidean warping along with a discussion of a Matlab implementation. Secondly an application of image warping is given; namely image mosaicing where images are stitched together – e.g. to form a panoramic view. Effort has been put into making the text as self-containing as possible. However, basic knowledge of lin...
