چکیده
| We consider the problem of segmenting a digitized image consisting of two univariate populations. Assume a-priori knowledge allows incomplete assignment of voxels in the image, in the sense that a fraction of the vox-els can be identiied as belonging to population 0 , a second fraction to 1 , and the remaining fraction have no a-priori identiication. Based upon estimates of the short length scale spatial covariance of the image, we develop a method utilizing indicator kriging to complete the image segmenta-tion.

متن کاملIeee Transactions on Pattern Analysis and Machine Intelligence
The role of moments in image normalization and invariant pattern recognition is addressed. The classical idea of the principal axes is analyzed and extended to a more general definition. The relationship between moment-based normalization, moment invariants, and circular harmonics is established. Invariance properties of moments, as opposed to their recognition properties, are identified using ...
متن کاملPhotorealistic Monocular Gaze Redirection Using Machine Learning.
We propose a general approach to the gaze redirection problem in images that utilizes machine learning. The idea is to learn to re-synthesize images by training on pairs of images with known disparities between gaze directions. We show that such learning-based re-synthesis can achieve convincing gaze redirection based on monocular input, and that the learned systems generalize well to people an...
متن کاملRotation Invariance
This chapter discusses the issue of rotational invariance of a texture analysis system: i.e. one desires that the outcome of the analysis is not aaected by the orientation of the input image. We argue that the orthogonal DWT (section 3.4) is very impractical for such an analysis due to its separable nature in 2 dimensions. We therefore employ the non-separable wavelet frames (section 3.3). We d...
متن کاملFixed Points of Belief Propagation - An Analysis via Polynomial Homotopy Continuation.
Belief propagation (BP) is an iterative method to perform approximate inference on arbitrary graphical models. Whether BP converges and if the solution is a unique fixed point depends on both the structure and the parametrization of the model. To understand this dependence it is interesting to find all fixed points.
متن کاملAn Algorithmic Analysis of Variational Models for Perceptual Local Contrast Enhancement
Color cast cancellation and local contrast enhancement are very important problems in computer vision. In this paper we review the algorithm proposed by Palma-Amestoy et al. [A perceptually inspired variational framework for color enhancement, IEEE Transactions on Pattern Analysis and Machine Intelligence, 21 (2009), pp. 458–474], present results and evaluate the impact of a change in the param...
