matlab 小波函数处理图片的轮廓问题(matlab wave function to handle pictrure scale)

一些用matlab编的经济学程序，都是很经典的一些程序(Matlab made some use of economics procedures are some of the classic procedure)

this code first reads an image and decomposed it in discrete wavelet transformation.hl1 and hl2 are extracted to embed watermark. watermark is added to hl1 and lh1 and inverse dwt is applied.

first code written in c++ for generating 3D tetrahedral elements inside unite cube with sphere inside it.

This Matlab script solves a particular case of the parabolic PDE studied in class using the CrankNicolson finite difference algorithm.

This is the BER plot for QPSK..

Abstract—In this paper, a new lossy technique based on wavelet transform for compression of breast ultrasound images is presented. The experiments are performed on 16 different wavelet functions and the quality of reconstructed images is evaluated by using Compression Ratio (CR), Normalized Mean Square Error (NMSE), Normalized Absolute Error (NAE), and Peak Signal to Noise Ratio (PSNR) criterion. An ultrasonographer performed the subjective assessment. This study shows that among the utilized wavelets,
