This article introduces the theory of continuous wavelet transform and dyadic wavelet transform , and the practical condition of their converse transform 本文研究了连续小波变换和离散栅格下小波变换的理论，以及相关的正反演条件。
Participate in dyadic method having already come into being close to 7 years , before much effective course verifying , being able to transfer of field group enthusiasm 参与式方法已产生了近7年，在很多领域经过验证，能够有效的调动群体的积极性。
The dyadic boolean operation whose result has the boolean value1if and only if the first operand has the boolean value1and the second has boolean value0 二元布尔运算，当且仅当第一个操作数具有布尔值1 ，第二个操作数具有布尔值0时，其结果才为布尔值1 。
The dyadic boolean operation whose result has the boolean value 1 if and only if the first operand has the boolean value 1 and the second has boolean value 0 二元布尔运算,当且仅当第一个操作数具有布尔值1 ,第二个操作数具有布尔值0时,其结果才为布尔值1 。
The dyadic boolean operation whose result has the boolean value0if and only if the first operand has the boolean value0and the second has the boolean value1 二元布尔运算，当且仅当第一个操作数具有布尔值1 ，第二个操作数具有布尔值0时，其结果才为布尔值1 。
The dyadic boolean operation whose result has the boolean value 0 if and only if the first operand has the boolean value 0 and the second has the boolean value 1 一种二元布尔运算,在这种运算中,当且仅当第一个操作数的布尔值为0 ,第二个操作数的布尔值为1时,其结果的布尔值才为0 。
Then , these constructions of the families of bent complementary function pairs that are based on some special arrays , for example orthogonal column arrays and dyadic perfect arrays , are studied 然后，研究了利用列正交阵列、并元最佳阵列偶而得到的bent互补函数偶族的构造方法。
It ' s very useful in sar images analysis . dyadic wavelet transform is not shift - invariant , which is always requested in pattern recognition , so new 2d - wavelet transform method is needed 传统二进小波变换缺少模式识别所需的移不变特征，需要确定适合于模式识别的具有移不变特性的二维小波变换。
The multiscale edge or texture feature of the image is characterized using the edge detection method based on dyadic wavelet transform . the watermark is embedded into the phase components of the multiscale edges 利用基于二进小波变换的边缘检测方法刻画图像的多尺度边缘和纹理特征，在边缘的相位成分中嵌入水印。
It can be testified that the wavelet is a two - dimensional dyadic wavelet . the computation of the wavelet transform in image processing depends only upon the wavelet functional values at a few integer points 这类二维二进小波对图像的小波变换及其相关的计算只依赖于几个整数点上的小波函数值，实现了某种程度上的快速算法。
