SIFT
- MATLAB实现图像的SIFT特征提取，并做在不同光照、不同视角下的特征匹配-SIFT MATLAB for image feature extraction, and to do in different lighting, different from the Perspective of feature matching
feature_extraction_face_GE
- An automatic facial feature extraction method is presented in this paper. The method is based on the edge density distribution of the image. In the preprocessing stage a face is approximated to an ellipse, and genetic algorithm is applied
plot3d_2
- This function produces an image of a 3D object defined by matrix a(l,m,n) in terms of voxels the image is a view after rotating the object by angles alfa and beta (in degree) b is the image and d is its ditance to the viewer matrix The first figure d
Meanshif-Detection
- ：Mean—shift算法是一种非参数密度估计算法，可以实现快速的最优匹配，在目标的实时跟踪领域起着非常 重要的作用。为了有效的将Mean—shift算法应用到灰度图像中，采用了以方向直方图建立目标模型的策略，提出了在灰 度图像中以Mean—shift为核心的目标跟踪算法。实验结果表明，该算法具有不受光照条件影响的优点，在低对比度的情 况下仍能实现稳定、实时的跟踪目标。-: Mean-shift algorithm is a nonparametric density estimat

WYDP20
- An Automatic Wavelet-based Nonlinear Image Enhancement Technique for Aerial Imagery Recently we proposed a wavelet-based dynamic range compression algorithm to improve the visual quality of digital images captured in the high dynamic range
Zg
- Closely related to image processing are computer graphics and computer vision. In computer graphics, images are manually made physical models of objects, environments, and lighting, instead of being acquired (via imaging devices such as cameras) natu
