Natural-Image-Sketching-Production
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)

DFT&DCT
编程实现二维8*8图像块的DFT,DCT变换
输入一副RGB图像,将其转化为YCbCr颜色空间,然后对Y分量做分块DFT变换,保存为灰度图像,统计计算时间
编程实现8*8块DCT变换,然后分别显示,当使用64个DCT系数里面的一些系数进行重构,比较其质量;同时熟悉采用FFT来实现DCT变换的思想,并显示2维8*8DCT变换的基函数图像(Programming the DFT, DCT transform of two dimensional 8*8 image block
Input a pair of RGB images, transform it into YCbCr color space, then divide the Y component into block DFT transform, save as gray image, and calculate the calculation time
The 8*8 block DCT transform is implemented by programming, and then it is shown that when using some coefficients in 64 DCT coefficients, the quality is reconstructed. Meanwhile, the idea of DCT transformation is familiar with FFT, and the base function image of the 2 dimensional 8*8DCT transform is displayed.)
