SiftGPU-V370
说明: 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 then uses a GPU/CPU mixed method to efficiently build compact keypoint lists. Finally keypoints are processed parallely to get their orientations and descriptors.
SiftGPU is inspired by Andrea Vedaldi s sift++[2] and Sudipta N Sinha et al s GPU-SIFT[4] . Many parameters of sift++ ( for example, number of octaves, number of DOG levels, edge threshold, etc) are also available in SiftGPU. The shader programs are dynamically generated according to the parameters that user specified.
SiftGPU also includes a GPU exhaustive/guided sift matcher SiftMatchGPU. It basically multiplies the descriptor matrix on GPU and find closest feature matches on GPU. Both GLSL and CUDA implementations are provided.

RRT-path-panning-algorithm
本文以自主驾驶车辆为实际应用背景.提出了一种改进的RRT(快速随机搜索树)路径规划算法.该路
径规划算法将非完整性约束条件与双向多步扩展RRT搜索算法相结合,在提高搜索效率的同时保证了规划路径的可
行性.同时将路径点作为B样条基函数的控制点,用三次B样条函数来拟合控制点生成平滑可跟踪的路径.通过在平
面障碍物环境下实验,验证了该算法的有效性.(AimingattheapplicationofALV(automaticlandvehicle),animprovedRRT(RapidlyRandom?exploring

Abstract—Noninvasive ultrasound imaging of carotid plaques
allows for the development of plaque-image analysis methods associated
with the risk of stroke. This paper presents several plaqueimage
analysis methods that have been developed over the past
years. The paper begins with a review of clinical methods for visual
classification that have led to standardized methods for image
acquisition, describes methods for image segmentation and denoizing,
and provides an overview of the several texture-feature
extraction and classification methods that have been applied. We
provide a summary of emerging trends in 3-D imaging methods
and plaque-motion analysis. Finally, we provide a discussion of the
emerging trends and future directions in our concluding remarks.

doublefunction
* 说明:
该函数将对图象进行(成对函数匹配)操作。需要注意的是,此程序先要求对图像进行特征提取及形态学操作等,使其成为二值图像。(* Note: This function will be images (paired function matching) operation. Note that this procedure require image feature extraction and morphological operations, making it a binary image.)
