Image Warping for Shape Recovery and Recognition
We demonstrate that, for a large class of reflectance functions, there is a direct relationship between image warps and the corresponding geometric deformations of the underlying three-dimensional objects. This helps explain the hidden geometrical assumptions in object recognition schemes which involve two-dimensional image warping computed by matching image intensity. In addition, it allows us...

متن کاملDiscrimintive Image Warping with Attribute Flow
We address the problem of finding deformation between two images for the purpose of recognizing objects. The challenge is that discriminative features are often transformation-variant (e.g. histogram of oriented gradients, texture), while transformation-invariant features (e.g. intensity, color) are often not discriminative. We introduce the concept of attribute flow which explicitly models how...
متن کاملA 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...
