Abstract

Abstract:

The cognitive mechanisms of human brain based on fMRI were studied to get the image features that the subjects paied attention to when they saw the images. The shape, texture and color perception regions were located in the brain for every subject through one fMRI experiment, and these regions were defined as interest regions. The mean percent bold signal changed in interest regions was calculated when the subjects were watching face, bus, dinosaur and mountain images through another fMRI experiment. The image features that the subjects pay attention to were different when they saw different images.

Key words: color feature;shape feature, ROI(regions of interest);percentage of bold signal change, texture feature, fMRI(functional magnetic resonance imaging)
