Obtaining accurate and timely crop mapping is essential for refined agricultural refinement food security. Due to the spectral similarity between different crops, influence of image resolution, boundary blur spatial inconsistency that often occur in remotely sensed mapping, still faces great challenges. In this article, we propose extend a neighborhood window centered on target pixel enhance re...

Feature matching is a key method of feature-based image registration, which refers to establishing reliable correspondence between feature points extracted from two images. In order eliminate false matchings the initial matchings, we propose simple and efficient method. The principle our maintain topological affine transformation consistency among neighborhood matches. We formulate this problem...

This paper presents a novel distance concept, Vector-Distance (VD) for high dimensional data. VD extends traditional scalar-distance to a vector-like fashion by collecting multi partial distances from diverse angles. These partial distances are derived from random projections, and they preserve individual features of dimensions as much as possible. Based on VD definition, a method family for ne...

Photovoice is a qualitative community-based participatory research (CBPR) method used by researchers and communities to inform policy advocate for community change. was piloted within an established intervention, Your Family, Neighborhood (YFYN), predominantly Latinx community. YFYN dual-generation, evidence-based, manualized curriculum supporting strengthening bonds between parents their child...

Research on adolescent use of substances has long sought to understand the family factors that may be associated with use of different substances such as alcohol, tobacco and marijuana. However, scant attention has been focused on these questions in Latin American contexts, despite growing concerns about substance use among Latin American youth. Using data from a sample of 866 Chilean youth, we...

Although the neighborhood microsystem is recognized as an important domain for adolescent development, relative to the family and peer contexts, neighborhood factors have been understudied in relation to adolescent substance abuse. In addition, recent research suggests that risk factors for adolescent substance use may differ for African Americans when compared to Caucasian youth. This study in...
