Smal-l-Target--Detection
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. )
