UAV Image Mosaicking Based on Multiregion Guided Local Projection Deformation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
The goal of unmanned aerial vehicle (UAV) image mosaicking is to create natural- looking mosaics without artifacts due to the parallax of the image and relative camera motion.

THE EFFECT OF SHADOW AREA ON SGM ALGORITHM AND DISPARITY MAP REFINEMENT FROM HIGH RESOLUTION SATELLITE STEREO IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Semi Global Matching (SGM) algorithm is known as a high performance and reliable stereo matching algorithm in photogrammetry community. However, there are some challenges using this algorithm especially for high resolution satellite stereo images over ...

Lightning strikes to tall objects: Currents inferred from far electromagnetic fields versus directly measured currents [PDF]

open access: yesGeophysical Research Letters, 2007
We have derived far‐field‐to‐current conversion factors for lightning strikes to tall objects for (1) the initial peak current at the object top, (2) the largest peak current at the object top, and (3) the peak current at the object bottom. These far‐field‐to‐current conversion factors are needed for proper interpretation of peak currents reported by ...

Seeing the natural world: a tension between pupils’ diverse conceptions as revealed by their visual representations and monolithic science lessons [PDF]

open access: yes, 2007
In this paper we report on drawings of the natural environment produced by a sample of 13-14 year-olds. One of our interests is in the extent to which these young people see the world in the way rewarded in science lessons.

OBJECT BASED AGRICULTURAL LAND COVER CLASSIFICATION MAP OF SHADOWED AREAS FROM AERIAL IMAGE AND LIDAR DATA USING SUPPORT VECTOR MACHINE [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Aerial image and LiDAR data offers a great possibility for agricultural land cover mapping. Unfortunately, these images leads to shadowy pixels. Management of shadowed areas for classification without image enhancement were investigated.

The Use of Lexical and Referential Cues in Children’s Online Interpretation of Adjectives [PDF]

open access: yes, 2013
Recent research on moment-to-moment language comprehension has revealed striking differences between adults and preschool children. Adults rapidly use the referential principle to resolve syntactic ambiguity, assuming that modification is more likely ...

Parietal lesions produce illusory conjunction errors in rats

open access: yesFrontiers in Integrative Neuroscience, 2012
When several different objects are presented, visual objects are perceived correctly only if their features are identified and then bound together. Illusory-conjunction errors result when an object is correctly identified but is combined incorrectly. The

Gated-Attention Architectures for Task-Oriented Language Grounding

open access: yes, 2018
To perform tasks specified by natural language instructions, autonomous agents need to extract semantically meaningful representations of language and map it to visual elements and actions in the environment. This problem is called task-oriented language
