title: [Enhancement of image used in optical imaging of intrinsic signal].
abstract: Optical imaging of intrinsic signals is a secondary image of the cerebral cortex. The weak optical signal is decided by anatomical structure of brain. The spatial filter is a powerful technology for de-noising and image enhancement. We used different linear and nonlinear filters to deal with optical imaging. Furthermore, we compared the degree of noise suppression and discussed the image details. Our result showed that nonlinear median filter can keep more image details with effective noise reduction. It is useful for image enhancement of optical imaging.
