A bottom–up model of spatial attention predicts human error patterns in rapid scene recognition [PDF]

open access: yes, 2007
Humans demonstrate a peculiar ability to detect complex targets in rapidly presented natural scenes. Recent studies suggest that (nearly) no focal attention is required for overall performance in such tasks.

Integration of Low-Cost GNSS and Monocular Cameras for Simultaneous Localization and Mapping

open access: yesSensors, 2018
Low-cost Global Navigation Satellite System (GNSS) receivers and monocular cameras are widely used in daily activities. The complementary nature of these two devices is ideal for outdoor navigation.

Space Target Tracking with the HRRP Characteristic-Aided Filter via Space-Based Radar

open access: yesRemote Sensing, 2023
Approaching space target tracking is a typical and challenging mission in the space situational awareness (SSA) field. As the space-based radar is able to monitor the space targets of interest full-weather all-time, the space-based radar system is ...

DP–MHT–TBD: A Dynamic Programming and Multiple Hypothesis Testing-Based Infrared Dim Point Target Detection Algorithm

open access: yesRemote Sensing, 2022
The detection and tracking of small targets under low signal-to-clutter ratio (SCR) has been a challenging task for infrared search and track (IRST) systems. Track-before-detect (TBD) is a widely-known algorithm which can solve this problem.

Learning to Read by Spelling: Towards Unsupervised Text Recognition [PDF]

open access: yes, 2018
This work presents a method for visual text recognition without using any paired supervisory data. We formulate the text recognition task as one of aligning the conditional distribution of strings predicted from given text images, with lexically valid ...

During visual word recognition, phonology is accessed within 100 ms and may be mediated by a speech production code: evidence from magnetoencephalography [PDF]

open access: yes, 2010
Debate surrounds the precise cortical location and timing of access to phonological information during visual word recognition. Therefore, using whole-head magnetoencephalography (MEG), we investigated the spatiotemporal pattern of brain responses ...

Focus accent, word length and position as cues to L1 and L2 word recognition [PDF]

open access: yes, 2005
The present study examines native and nonnative perceptual processing of semantic information conveyed by prosodic prominence. Five groups of German learners of English each listened to one of 5 experimental conditions. Three conditions differed in place

The effect of three practice conditions on the consistency of chronic dysarthric speech [PDF]

open access: yes, 2004
This study investigated whether it is possible for people with chronic dysarthria to adjust their articulation in three practice conditions. A speaker dependent, speech recognition system was used to compare participants' practice attempts with a model ...

Joint Tracking and Classification of Extended Targets Using Random Matrix and Bernoulli Filter for Time-Varying Scenarios

open access: yesIEEE Access, 2019
In surveillance applications, the extent states and measurements of extended targets received by sensors are time-varying. In this paper, we propose a joint tracking and classification (JTC) method for single extended target under the presence of clutter

Learning joint feature adaptation for zero-shot recognition [PDF]

open access: yes, 2016
Zero-shot recognition (ZSR) aims to recognize target-domain data instances of unseen classes based on the models learned from associated pairs of seen-class source and target domain data.
