We collect environmental information through our sensory organs, perceive them suitably to execute the task in hand. Examples of such tasks are abundant, like driving, operating machines, playing games, hunting, or mushroom picking on mountains. While executing such tasks, there is a marked difference in efficiency and accuracy between an expert and a novice. An expert is attentive to only what is...
Research on spatial attention has traditionally focused on spatially selective processing within a single sensory modality. But recent research has proved that selective attention is a mechanism that is not limited to a single sensory modality but can encompass or spread across multiple sensory systems. The present study investigated whether the crossmodal spatial attention influences the processing...
In the conventional rate distortion optimization (RDO) video coding, the measure of distortion is mainly from the perspective of signal processing, while dose not fully take into account the characteristics of visual perception. People have concerns about not only the information of independent pixels, but also the temporal and spatial correlations between them. For different video content, human...
A system for image semantic information extraction and retrieval based on combination between top-down, target-driven and bottom-up, image-driven visual saliency distinguishing is presented. It simulates the analogous procedures of visual system of primates. It consists of four major components: selective attention, semantics extraction, semantics modeling and image retrieval. The design of selective...
During the process of school education, children with LD have defects both in spatial WM and controlled attention. However, research on the relation between them is few. Therefore, the study focused on investigating the relation using IOR paradigm as research method of controlled attention. Inhibition of Return (IOR) is the hysteresis phenomenon shown by the reaction of the previous note on the location...
People often fail to see salient but unexpected objects in absorbing tasks. The present study was aimed to investigate the role of inhibitory mechanism for such attentional lapse. By manipulating similarity between distractors and unexpected objects, the first experiment shows the effect of inhibition in affecting the possibility of blindness. By reducing the number of distractors, the second experiment...
Due to huge computational loads and the state of art of current hardware, nowadays how to implement real-time vision tasks on a signal chip is still a great interesting work. It is critical for eventually accomplishing biointelligence on robots, whatever humanoid robots, insect robots or even space robots. This paper presents a design of a so-called visual brain chip for robotic vision applications...
Selective attention to visual or auditory stimuli that elicits steady-state visual or auditory responses (SSVEP or ASSR respectively) amplifies the power of those flickering frequencies of the stimuli measured in the electroencephalography (EEG). The design of brain-computer interfaces (BCI) based on selective attention to auditory stimuli that elicits ASSRs has two major advantages: First, no much...
