Aligning images with multiple objectives
2008 IEEE Congress on Evolutionary Computation (IEEE World Congress on Computational Intelligence), 2008Most high level interpretation tasks in image analysis rely on image registration (alignment) process. Basically, image registration consists in finding the geometric transformation that best aligns two or several images. In this paper, we focus on mono-modality image alignment. The core task to do in this case is to put into correspondence two sets of

Besides stating the problem of image registration this chapter is built on the following parts : 1) Similarity estimation by level sets. We use the Fast Level Sets Transform (see the chapter on TV minimization) to extract reliable features from both images. To each feature we associate similarity invariants, then we consider pairs of features (F1, F2),

Multisensor alignment of image manifolds
2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013The access to many sources of satellite information is nowadays a reality. However, few methods allow to consider simultaneously data coming from different sensors, due to the differences in numbers of bands, spatial resolution and changes in the acquisition conditions.

Image alignment for 3D reconstruction in a SEM
Microelectronics Reliability, 2005In a previous paper [1] a procedure to extract the third dimension from back-scattered electron has been proposed. The 3D recovery process involves the acquisition of four images and the computation of surface gradients; thus, a specific algorithm finds the depth map of the given surface.

Automatic alignment of radionuclide images
Physics in Medicine & Biology, 1982The variability of the position, dimensions and orientation of a radionuclide image within the field of view of a gamma camera hampers attempts to analyse the image numerically. A method is described for using a set of training images of a particular type, in this case right lateral brain images, to define the likely variations in the position ...

Lighting Alignment for Image Sequences
2015Lighting is one of the challenges for image processing. Even though some algorithms are proposed to deal with the lighting variation for images, most of them are designed for a single image but not for image sequences. In fact, the correlation between frames can provide useful information to remove the illumination diversity, which is not available for

Image registration by aligning entropies
Proceedings of the 2001 IEEE Computer Society Conference on Computer Vision and Pattern Recognition. CVPR 2001, 2005Maximization of mutual information is a powerful method for registering images (and other data) captured with different sensors or under varying conditions, since the technique is robust to variations in the image formation process. On the other hand, the high level of robustness allows false positives when matching over a large search space and also ...

Field‐aligned Quadrangulation for Image Vectorization
Computer Graphics Forum, 2019AbstractImage vectorization is an important yet challenging problem, especially when the input image has rich content. In this paper, we develop a novel method for automatically vectorizing natural images with feature‐aligned quad‐dominant meshes. Inspired by the quadrangulation methods in 3D geometry processing, we propose a new directional field ...

Asymmetric gradient-based image alignment
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009A new method for template-based image alignment is presented in this paper. A gradient-based optimization of motion compensated error difference is addressed to solve the image alignment problem. Its novelty lies in the minimized error, which considers the bi-directional compensation of the reference template and the current image onto each other in a ...
