In this paper, we evaluate the channel equalization performance of digital television terrestrial broadcasting for mobile reception. To improve reception performance under serious fading environments, high-order interpolation for precise channel estimation is required. However, these high-order interpolation methods generally need an immense amount of temporal memory. To reduce the required memory,...
Accurate liver segmentation from abdominal computed tomography (CT) images is one of the most important steps for computer aided diagnosis (CAD) for liver CT. In this paper, we present a hybrid method for semiautomatic delineation of the liver contours on CT images. Firstly, the CT images are enhanced and denoised by a method based on histogram equalization and anisotropic diffusion filtering; Then,...
We investigated channel estimation with scattered pilots (SPs) in digital terrestrial television broadcasting (DTTB) and the performance of a receiver with a two-dimensional (2D) filter. High-accuracy interpolation is necessary because we perform channel equalization with SPs, which are inserted in transmit signals nonrectangularly. This interpolation is performed with a 2D filter that has a nonrectangular...
