This MATLAB package implements kernel descriptors proposed in [1-2]. There are nine directories in the package: - demo_rgb: Demo scripts to show the usage of kernel descriptors for image recognition. - demo_rgbd: Demo scripts to show the usage of kernel descriptors for RGB-D object recognition - emk: Efficient match kernels that generate image/object level features based on kernel descriptors. Please download the emk package from http://www.cs.washington.edu/homes/lfb/software/EMK.htm. Copy the subfolder /emk_1.0/emk/ to kdes_2.0/emk/. - helpfun: Helpful functions such as K-Means and power transformations. - images: Directory of storing training and test data. - kdes: Kernel descriptors for RGB and depth images. - liblinear-1.5-dense: Liblinear in the dense format, modified by Xiaofeng Ren. - liblinear-1.5-dense-float: Liblinear in the dense float format, modified by Xiaofeng Ren. - lsvm: A Matlab version of linear SVMs [1] Liefeng Bo, Xiaofeng Ren and Dieter Fox, Kernel Descriptors for Visual Recognition, Advances in Neural Information Processing Systems (NIPS), 2010.
