Summation of texture segregation across orientation and spatial frequency: electrophysiological and psychophysical findings.

abstract：:How we attend to and search for objects in the real world is influenced by a host of low-level and higher-level factors whose interactions are poorly understood. The vast majority of studies approach this issue by experimentally controlling one or two factors in isolation, often under conditions with limited ecologica...
