GPU 编程示例，介绍GPU结合GLSL，CG实现图像处理及数学运算，值的学习。-GPU Sample

本程序借助OpenGL及其高级着色语言GLSL实现了图像降噪，锐化，对比度增强等图像处理操作！-With this procedure and its high-level shading language GLSL OpenGL implementation of image noise reduction, sharpening, contrast enhancement and other image processing!

使用gpu、cpu并行进行sift算子计算匹配，能够在原来的基础上加速处理，但对显卡要求较高，具体环境配置使用方法可以参照mannual-SiftGPU is an implementation of SIFT [1] for GPU. SiftGPU processes pixels parallely to build Gaussian pyramids and detect DoG Keypoints. Based on GPU list generation[3], SiftGPU th
