Segment-Based Stereo Matching Using Belief Propagation and a Self-Adapting Dissimilarity Measure
"... A novel stereo matching algorithm is proposed that utilizes color segmentation on the reference image and a selfadapting matching score that maximizes the number of reliable correspondences. The scene structure is modeled by a set of planar surface patches which are estimated using a new technique t ..."

Color Histogram Specification by Histogram Warping
"... Histogram warping is a novel histogram specification technique for use in color image processing. As a general purpose tool for color correction, our technique constructs a global color mapping function in order to transform the colors of a source image to match a target color distribution to any de ..."

Image Warping Using few Anchor Points and Radial Functions
- Computer Graphics Forum
, 1995
"... Transformations based on radial basis functions have proven to be a powerful tool in image warping. In the present work we decompose these transformations into linear and radial terms, and show examples where such a decomposition is advantageous. Locally supported basis functions are introduced. Sev ..."

transformation of a bounded subregion of the plane onto itself with the color or grey-scale associated with each point transformed accordingly. Warping of objects, especially of elastic ones such as human faces, appears in various computer graphics and computer vision applications. These include areas
Rapid shape acquisition using color structured light and multi-pass dynamic programming
- In The 1st IEEE International Symposium on 3D Data Processing, Visualization, and Transmission
, 2002
"... Figure 1. In this paper, we show how to reconstruct the shape of a scene, such as the two hands shown on the left, given a single photograph of the scene under color-striped illumination shown at center. A novel dynamic programming method leads to the geometric reconstruction on the right, shown as ..."

The correspondence problem is solved using a novel, multi-pass dynamic programming algorithm that eliminates global smoothness assumptions and strict ordering constraints present in previous formulations. The resulting approach is suitable for generating both highspeed scans of moving objects
Plane-based content-preserving warps for video stabilization
- In Proc. CVPR
"... Recently, a new image deformation technique called content-preserving warping (CPW) has been successfully employed to produce the state-of-the-art video stabilization results in many challenging cases. The key insight of CPW is that the true image deformation due to viewpoint change can be well appr ..."

Sketch-based warping of RGBN images
"... While current image deformation methods are careful in making the new geometry seem right, little attention has been given to the photometric aspects. We introduce a deformation method that results in coherently illuminated objects. For this task, we use RGBN images to support a relighting step inte ..."

integrated in a sketch-based deformation method. We warp not only colors but also normals. Normal warping requires smooth warping fields. We use sketches to specify sparse warping samples and impose additional constraints for region of interest control. To satisfy these new constraints, we present a novel
Discriminative 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 ..."

Illumination Estimation Using a Multilinear Constraint on Dichromatic Planes
"... A new multilinear constraint on the color of the scene illuminant based on the dichromatic reflection model is proposed. The formulation avoids the problem, common to previous dichromatic methods, of having to first identify pixels corresponding to the same surface material. Once pixels from two or ..."

or more materials have been identified, their corresponding dichromatic planes can be intersected to yield the illuminant color. However, it is not always easy to determine which pixels from an arbitrary region of an image belong to which dichromatic plane. The image region may cover an area of the scene
A Stereo Approach that Handles the Matting Problem via Image Warping
"... We propose an algorithm that simultaneously extracts disparities and alpha matting information given a stereo image pair. Our method divides the reference image into a set of overlapping, partially transparent color segments. Each segment pixel is assigned an alpha value and color. The disparity ins ..."

Its basic idea is to use the three parameters for generating artificial views representing the left and right images. If alphas, colors and disparity planes are correct
A Layered Stereo Algorithm Using Image Segmentation And Global Visibility Constraints

, 2004

Each segment is modelled as a plane. Robustness of the depth representation is achieved by the use of a layered model. Layers are extracted ..."

The quality of the disparity map is measured by warping the reference image to the second view and comparing it with the real image. Z-buffering enforces visibility and allows the explicit
