对输入图像进行预处理后提取目标轮廓，经过归一化处理得到目标形 状的平移、尺度不变的链状表达，再通过小波变换进行多尺度分析；引入Zernike 矩，利用Zernike 矩的特性，实现小波表达的旋转不变性，解决了小波变换对起始点的依赖。-right to import images from pretreatment profile targets, after processing to be a target shape translation, The scale-invariant

借助小波变换在时频分析上的优点，提取地面运动目标的回波信号特征在目标识别中加以运用-With wavelet transform in time-frequency analysis of the advantages of extracting ground moving target echo signal characteristics to be used in target recognition

matlab基于小波变换的语音增强处理，语音增强的主要目标，就是从带噪语音信号中提取尽可能纯挣的原始语音-matlab speech enhancement based on wavelet transform processing, the main objective of speech enhancement, is from the noisy speech signal to extract the original voice as pure earn

通过分析天空背景下红外运动小目标、噪音以及背景的特征，提出一种检测方法。首先利用向量小波变换对运动图像进行预处理；其次采用图像差分进行目标的粗检测，提取出候选目标；最后可根据运动目标和噪音的特征对候选目标进行识别，检测出真实的运动小目标。实验证明，该方法可有效检测天空背景下红外运动小目标。-According to small moving infrared target detection in the sky background，a detection algorithm is pre
