an algorithm for infrared image enhancement based on gray scale transform 一种基于灰度变换的红外图像增强算法
based on scale transform method of time, an experiential formula is proposed for viscoelastic stress relaxation process 摘要通过时间标度变换方法,提出了粘弹性应力松弛过程的一个经验公式。
lifting scheme can be used to calculate discrete wavelet transform ( dwt ) efficiently, it is composed of a number of lifting steps and the scaling transform 提升方法是计算离散小波变换的有效手段,它由提升步和拉伸变换组成。
the text is reflected using a scaling transform, but first a new origin is set to prevent the text from being drawn outside the viewable area of the form 文本是使用缩放转换反射的,但首先要设置新原点,防止将文本绘制到窗体的可视区域之外。
pslift first calculate all lifting steps of each level and each dimensional dwt, and then calculate the scaling transform . for example, when five level decompositions is implemented for cdf 9 7 wavelet, compared to the known methods, the number of multiplication needed is reduced by 20 % and 28 % corresponds to one dimensional dwt and two dimensional dwt, respectively 例如,对图像与视频压缩中应用广泛的cdf9/7小波,做一维5级分解时与现有方法相比,乘法运算量减少20,而做二维5级分解时,乘法运算量可以减少28。
