A Drawable that manages an array of other Drawables. These are drawn in array order, so the element with the largest index will be drawn on top.

点云关键点搜索，根据曲率极值法搜索关键点(PCL:keypoint detection, used for registration and segmentation)

phase congruency相位一致性计算，可以用于提取图像的特征，如边缘、角点等。(calculation of phase congruency phase coherence, can be used to extract image features, such as edge, corner points.)

实现了读取一个bmp图片的傅里叶变换 使用C语言实现 读取一个 24位 图 转换为8位灰度图后，进行傅里叶变换处理（二维） 采用快速傅里叶变换——蝶形算法 北航图像处理作业~需要进一步交流 请联系qq 422563357(Reads a bmp image to achieve a Fourier transform using C language Northern image processing operations)

说明：  在ENVI中利用此程序可将多光谱影像拆分为单个波段。(In ENVI, multi-spectral images can be divided into single bands by using this program.)

共厄梯度方法!!!本程序适用于求解形如f(x)=1/2*x Ax+bx+c二次函数的稳定点； (total Eritrea gradient method! ! ! The procedure will be applicable to solve the shape of f (x) = 1/2* x Ax bx c quadratic Function stability;)

压缩感知大牛陆吾生写的代码，可以直接运行，有机会可以搜一下他的视频，真的讲的好(Compressed sensing born Daniel Lu I write code that can be run directly, have the opportunity to search about his video, really good talk)

一种基于non-sample的纹理合成demo，程序性能还有待优化，效果还不错.(texture synthesis demo.)
