This library contains helper functions to read image frames into matlab from Video file using DirectShow. This library has borrowed codes from Ashwin Thangali s "DirectShow (DirectX) based AVI file reader", and it can read multiple video formats besides avi. Features: a) can read frames from rmvb, avi, etc. b) handles most codecs installed on the system d) its implementation is only based on the IMediaDet interface -- Depending on your Matlab version, the .mexw32 files may need to be renamed as .dll -- The library usage is as follows, [avi_hdl, avi_inf] = dxVideoOpen(avi_filename) pixmap = dxVideoReadMex(avi_hdl, frame_num) img = reshape(pixmap,[avi_inf.Height,avi_inf.Width,3]) dxVideoCloseMex(avi_hdl) -- recompile the library I have compiled the code with the DirectShow lib in Microsoft DirectX 9.0 SDK Update (December 2004) -- known limitation a)only works for windows :( b)may be slow for big image frames and some codecs.

Abstract There are a number of interesting variable selection methods available beside the regular forward selection and stepwise selection methods. Such approaches include LASSO (Least Absolute Shrinkage and Selection Operator), least angle regression (LARS) and elastic net (LARS-EN) regression. There also exists a method for calculating principal components with sparse loadings. This software package contains Matlab implementations of these functions. The standard implementations of these functions are available as add-on packages in S-Plus and R. Keywords LASSO, LARS, SPCA, Matlab, Elastic Net, Sparse, Sparsity, Variable selection
