概要	Optical coherence tomography (OCT) is widely applied in ophthalmology for the non-invasive nature. Its widespread application has motivated the development of intraoperative OCT for real-time tomographic visualization of surgical intervention. However, the large speckle noise and low contrast affect the doctors viewing and the segmentation of retinal layers, which are critical for disease diagnosis. Image enhancement, as preprocessing of disease diagnosis is very important. The presented image enhancement algorithms, like the well-known BM4D, cost too much computational time, thus they cannot be adopted in real-time image enhancement during such intraoperative diagnosis or surgery. Therefore, we present a new fast OCT image enhancement algorithm.
