Wiener_Process

This is a collection of GUIs meant to serve either to answer specific questions about writing GUIs or as a teaching tool to aid in learning how to write MATLAB GUIs without GUIDE.

A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images.

205-GHz (Al,In)N/GaN HEMTs.more than 15 years of development, AlGaN/GaN high-electron-mobility transistors (HEMTs) have become the most technologically mature form of GaNbased HEMTs. There is, however, growing evidence that the total strain (i.e., the lattice-mismatch and piezoelectric contributions) limits the reliability of conventional AlGaN/GaN HEMTs
