Image Restoration with Two-Dimensional Adaptive Filter Algorithms
Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
متن کاملThree-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
متن کاملThree dimensional image restoration in fluorescence lifetime imaging microscopy.
A microscope set-up and numerical methods are described which enable the measurement and reconstruction of three-dimensional nanosecond fluorescence lifetime images in every voxel. The frequency domain fluorescence lifetime imaging microscope (FLIM) utilizes phase detection of high-frequency modulated light by homodyne mixing on a microchannel plate image intensifier. The output signal at the i...
متن کاملTotal Variation Based Image Restoration of Three Dimensional Microscopic Objects
The inverse problem involving the determination of a three-dimensional biological structure from images obtained by means of optical-sectioning microscopy is ill-posed. Regularization methods must often be used in order to obtain a reasonable solution. Recently, the Total Variation (TV) regularization, as proposed b y Rudin, Osher and Fatemi [ll], has become very popular for this purpose. A n i...
متن کاملThree-dimensional noisy image restoration using filtered extrapolation and deconvolution
The problem of restoration in fluorescence 1 microscopy has to deal at the same time with blurring 2 and photon noise. Their combined effects corrupt the 3 image by inserting elements that do not belong to the 4 real object and distort the contrast. This hinders the 5 possibility of using the images for visualization, recog6 nition and analysis using the three-dimensional data. 7 The algorithms...
