文件夹中的代码可以实现NSCT-PCNN融合 和 创新算法（NSCT-ML-PCNN ）图像融合其中NSCT-PCNN与创新算法NSXT分解的结果是一样的，所以只保存了一份。两个算法融合的结果都已经保存。NSSCTest.m文件：用于查看利用NSSC算法分解出的图像并保存。其中的nlevel可调test.m文件：用于产生融合结果，其中一个参数需要设置：Low_Coeffs_Rule：NSCT-PCNN进行图像融合时：Low_Coeffs_Rule选择PCNN；High_Coeffs_Rule选择PCNN创新算法的图像融合时：Low_Coeffs_Rule选择ML-PCNN；High_Coeffs_Rule选择PCNNqualityevl.m用于对图像结果进行质量评价

Design of Matlab® -Based Automatic Speaker Recognition Systems

现有自然图像素描画效果生成算法存在容易造成画面细节丢失，笔画线条单一等问题。针对这些问题，本文提出了一种改进的自然图像素描画效果生成算法，通过模拟艺术家创作素描画过程，分步生成素描画图像底纹和素描画场景笔画轮廓，采用8个方向卷积滤波提取图像中不同方向的细节信息，并使用不同长度不同粗细的笔画来模拟艺术家在创作过程中不同力度的绘画效果，最后合并素描画笔画效果和素描画图像底纹，得到与原输入自然图像内容一致，色调与艺术家绘制的素描画效果相同，笔画和底纹形式与实际素描画相似，真实感较强的素描画效果输出图像。大量实验结果表明本文方法可以生成高质量的自然图像素描画效果，与现有成熟的铅笔画生成技术相笔，本文方法具有较强的可比性。(The existing algorithms for natural image sketch production are easy to cause some problems such as the loss of image details, singleness of the stroke line. To solve these problems, this paper proposes an improved algorithm for the natural image sketch effect producing. By simulating the artist creation process of sketch, step-by-step generate image shading sketch image shading and drawing the scene outline stroke of the sketch image, using 8 directions of convolution filter to extract the details of different directions in the image, furthermore, using the stroke of different length and thickness to simulate the painting effect of different strength in the process of artist creation, finally we merge the sketch stroke effect and sketch image background to get the output image, which have consistent content with the original input image, have the same tonal effect with artists draw sketch, have the similar Stroke and background form with the actual sketch and have strong real sense in)
