Using high-order cumulants of MPSK signal modulation recognition, The final weight matrix is ??the filter coefficient, Including compression ratio, image restoration computing uptime and peak signal to noise ratio.

The wavelet denoising is a useful tool for various applications of image processing and acoustic signal processing for noise reduction.

Matlab中的图像处理实例，降噪，颜色提取，对比度增强，可以参考(Matlab image processing examples, noise reduction, color extraction, contrast enhancement, can be referred to)

The sky region of restored images often appears serious noise and color distortion using classical dark channel prior algorithm. To address this is- sue, we propose an improved dark channel prior algorithm which recognizes the sky regions in hazy ima
