Implementation-of-SIFT-detection
- 摘要:针对SIFT 特征提取的硬件实现结构复杂、难以达到实时性的问题,提出一种改进的高斯金字塔构建方法,该方法从 构建高斯金字塔的原始意义出发,大幅减少了所需的运算时间和存储单元。同时提出并验证了合适的SIFT 参数配置,以及 具体的硬件优化和并行实现方案,使整个系统可以在一片单独的FPGA 芯片上实现。该系统读入串行像素数据流,输出关键 点的特征描述符,并采用256×256 的图像对其进行了仿真验证,结果表明完全达到了实时的效果。 关键词:特征点 实时 尺度不变特征变换 现场可

Facial-Feature-Tarcking
- 研究优化人脸特征提取问题,针对长期以来在不贴标记点的情况下用传统的光流、Snake、可变模板等方法对纹理特征变化大的特征点不能有效跟踪,并且解决单独采用Gabor 小波系统开销大等问题,为了在人脸图像中提取准确信息,提出了人脸特征点的跟踪方法,分组采用改进的光流法和弹性图匹配的方法进行特征点跟踪。对眼睛、眉毛、上下眼皮等14 个表 情变化不大的特征点使用光流法进行跟踪,最后对变化大的嘴部8 个特征点运用Gabor 小波的弹性图匹配方法进行仿真。-Gabor wavelet research

GetSkeleton-using-OpenNI(Qt)
- MS的kinec SDK和OpenNI都提供了人体骨骼跟踪的算法,人体骨骼跟踪算法在kinect人体行为识别中非常重要,该识别过程通常被用来作为行为识别的第一步,比如说,通过定位人体中的骨骼支架,可以提取出人手的部位,从而可以把手的部分单独拿出来分析,这样就达到了手势的定位,而后面的手势识别则可以在刚刚定位出的领域进行处理。总而言之,一套有效的人体骨架追踪算法在kinect的一系列应用中非常有用,不过MS SDK和OpenNI虽然都提供了该算法类的直调用,但是其源码并没有开放,毕竟这是人家最核心
