为消除VGA到TV视频转换中的图像闪烁及获得图像的TV显示，分析了闪烁产生及分辨率变换的机理。
For eliminating graphic flicker and acquiring TV display of image from VGA to TV video conversion, the mechanisms of graphic flicker and resolution conversion are analyzed.
接下来它还要经过一些数学处理程序，比如小波分解，多重分辨率傅立叶分析，多相过滤，离散余弦变换等。
It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation.
该方法与反褶积方法比较，小波变换后的测井曲线更能反应细节信息，具有更高的纵向分辨率。
Compared with deconvolution method, the well log curves transformed by wavelet analysis contain more detailed information and reach higher vertical resolution.
