We propose a new algorithm for the estimation of functional activations in near infrared spectroscopic imaging. Our approach considers the activations to be support limited. We simultaneously estimate the function values as well as the support from the available measurements. Since this scheme exploit the structure inherent to functional imaging, it provide reconstructions with better spatial resolution and is more robust to noise.
我们提出了一种用于估计近红外光谱成像中功能激活的新算法。我们的方法认为激活是支持有限的。我们从可用测量中同时估计函数值以及支持。由于该方案利用了功能成像固有的结构，它能提供具有更好空间分辨率的重建，并且对噪声更具鲁棒性。
