Feature-independent neural coding of target detection during search of natural scenes.
Visual search requires humans to detect a great variety of target objects in scenes cluttered by other objects or the natural environment. It is unknown whether there is a general purpose neural detection mechanism in the brain that codes the presence of a wide variety of categories of objects embedded in natural scenes. We provide evidence for a feature-independent coding mechanism for detecti...
متن کاملVisual attention and target detection in cluttered natural scenes
Carl Gold Christof Koch California Institute of Technology Computation and Neural Systems Program Mail-Code 139-74 Pasadena, California 91125 Abstract. Rather than attempting to fully interpret visual scenes in a parallel fashion, biological systems appear to employ a serial strategy by which an attentional spotlight rapidly selects circumscribed regions in the scene for further analysis. The s...
متن کاملThe Spectral Independent Components of Natural Scenes
We apply independent component analysis (ICA) for learning an efficient color image representation of natural scenes. In the spectra of single pixels, the algorithm was able to find basis functions that had a broadband spectrum similar to natural daylight, as well as basis functions that coincided with the human cone sensitivity response functions. When applied to small image patches, the algor...
متن کاملLocal Independent Factorization of Natural Scenes
In this paper, we study sparse representation of large-size natural scenes via local spatial dependency decomposition. We propose a local independent factorization model of natural scenes and develop a learning algorithm for adaptation of the synaptic weights. We investigate the dependency of neighboring location of the natural scene patches and derive learning algorithm to train the visual neu...
متن کاملThe Temporal Cascade of Neural Processes Underlying Target Detection and Attentional Processing During Auditory Search.
The posterior visual event-related potential (ERP) component, the N2pc, has been widely used to study lateralized shifts of attention within visual arrays. Recently, Gamble and Luck (2011) reported an auditory analog of this activity (the fronto-central "N2ac"), reflecting the lateralized focusing of attention toward a Target sound among 2 simultaneous auditory stimuli. Here, we directed an ele...
