摘要： A singular point removing unit (12) removes a singular point as invisible high-frequency component noise from a degraded video signal and a reference video signal. A pixel value correcting unit (13) removes pixel-value bias added to the degraded video signal. The singular point removing unit (12) transforms the video signal into a spatial frequency, removes a high-frequency component, and restores the video signal by inverse transformation, or removes a singular point by using an averaging filter or a median filter. The pixel value correcting unit (13) obtains the correlation between the pixel values of the reference video signal and the corresponding pixel values of the degraded video signal, and corrects the pixel values of the reference video signal or the degraded video signal so as to match the pixel values of the degraded video signal with the pixel values of the reference video signal.

摘要： A method for automatic left ventricular (LV) inner border detection, the method comprising: performing image mapping on an echocardiogram, to produce a multi-level image map; converting the image map into a binary image, by attributing pixels of one or more darker levels of the image map to the LV cavity and pixels of one or more lighter levels of the image map to the myocardium; applying a radial filter to contours of the myocardium in the binary image, to extract an approximate inner border of the LV; and performing shape modeling on the approximate inner border, to determine the LV inner border.

摘要： To increase the processing speed when median processing in the time direction is performed on color images, pixel values of each channel (R, G and B values) are extracted from multiple temporally consecutive frame images; subsequently, identifiers (index numbers) corresponding to frame images from which the pixel values are extracted are assigned to the pixel values; subsequently, a sorting process is performed on a set of pixel values of one channel (G values) to obtain an identifier assigned to a median value thereof; subsequently, a pixel value to which an identifier identical with that assigned to the median value is assigned is selected as a median value of each channel; and subsequently, a median image is generated on the basis of the median value of each channel obtained for each pixel.

摘要： A method and apparatus are provided to improve large field of view CT image acquisition by using at least two scanning procedures: (i) one with the radiation source and detector centered and (ii) one in an offset configuration. The imaging data obtained from both of the scanning procedures is used in the reconstruction of the image. In addition, a method and apparatus are provided for detecting motion in a reconstructed image by generating a motion map that is indicative of the regions of the reconstructed image that are affected by motion artifacts. Optionally, the motion map may be used for motion estimation and/or motion compensation to prevent or diminish motion artifacts in the resulting reconstructed image. An optional method for generating a refined motion map is also provided.

摘要： A suite of processes and tools for preprocessing data prior to seismic interpretation including: voxel connectivity mapping, seismic response reduction, voxel suppression and voxel density. Voxel connectivity is used to assist with removing insignificant data. Seismic response reduction is used to reduce the seismic response of a given reflector to a lobe, such as a main lobe. Voxel suppression assists with highlighting and enhancing lithologic boundaries to aid in human and computer-aided interpretation. Voxel density scores the local significance of data trends within a volume, such as a 3-D seismic volume, to assist with the enhancement of these trends.

摘要： A method and apparatus for selectively blurring parts of an image set according to differences in disparity between successive images. As a result, the one-dimensional ringing edge artifacts, intrinsic to autostereoscopic displays, are hidden, thereby improving the perceived image quality of a multi-view autostereoscopic image. The method may involve detecting regions of disparity between adjacent views, and then blurring those regions by weighted local pixel averaging. The relationship between the blur radius and the disparity is preferentially non-linear to maintain sharpness of low disparity regions.
