Prob3

This set of MATLAB tools consists of some functions that I have found useful for basic image processing and blob analysis. The functions have been tested for MATLAB Version 5.3.0.10183 (R11) on PCWIN. Many of the files must be run as MEX files (MEX files are sometimes much faster than M-files). These must be compiled before use by typing "mex filename.c" at the MATLAB command prompt where filename.c is the relevant filename. Ensure that you are in the correct directory (e.g. cd c:..KFtools) and that the KFtools directory is included in the MATLAB path. The last three letters of all of the functions that are implemented as MEX files are m-e-x e.g. getboundarymex.(MATLAB This set of tools consists of some fu nctions that I have found useful for basic image processing and blob analysis.

matlab程序和说明文档。解决一类非线性最优求解问题，求解目标函数最小值。使用matlab中的fimincon函数，求有约束的非线性函数最小值。(matlab program to solve a class of nonlinear optimal problem solving, solving the objective function minimum. Use in matlab fimincon function, seeking a minimum of constrained nonlinear function.)

Tranformasi wavelet merupakan perbaikan dari transformasi Fourier. Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi tentang kombinasi skala dan frekuensi
