提出了一种新的基于小波包变换

和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题；

并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了

小目标的精确检测-The wavelet packets were applied to decompose the image into pyramid subbands at

different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement

criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact

detection result was obtained.
