The traditional dynamic programming stereo matching algorithms usually adopt the disparity assumption based on the intensity change of images; With the development of stereo matching technique, the disparity assumption based on image color segmentation is proved to meet better the need of true scenes. The paper introduces the disparity assumption into the stereo matching using dynamic programmi...

Question 1. Let f(z1, . . . , zn) be a holomorphic function on an open set U ⊂ C. For which t ∈ R is |f |t locally integrable? The positive values of t pose no problems, for these |f |t is even continuous. If f is nowhere zero on U then again |f |t is continuous for any t ∈ R. Thus the question is only interesting near the zeros of f and for negative values of t. More generally, if h is an inve...

In this article we propose a modification to the HMRF-EM framework applied to image segmentation. To do so, we introduce a new model for the neighborhood energy function of the Hidden Markov Random Fields model based on the Hidden Markov Model formalism. With this new energy model, we aim at (1) avoiding the use of a key parameter chosen empirically on which the results of the current models ar...

Recently, a distance function was defined on the face-centered cubic and body-centered cubic grids by combining weights and neighborhood sequences. These distances share many properties with traditional path-based distance functions, such as the city-block distance, but are less rotational dependent. We introduce four different error functions which are used to find the optimal weights and neig...

We give necessary and sufficient conditions for the existence of a continuous extension from a smallest-neighborhood space (Alexandrov space) X to the Khalimsky line. Using this result, we classify the subsets A ⊂ X such that every continuous function A → Z can be extended to all of X. We also consider the more general case of mappings X → Y between smallest-neighborhood spaces, and prove a dig...

OBJECTIVES To assess the relationship between cognitive function, socioeconomic status, and neighborhood deprivation (lack of local resources of all types, financial and otherwise). DESIGN Nationally representative cross-section. SETTING The English Longitudinal Study of Ageing (ELSA). PARTICIPANTS Seven thousand one hundred twenty-six community-dwelling individuals aged 52 and older and ...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...
