denoise In BayesShrink[5] we determine the threshold for each subband assuming a Generalized Gaussian Distribution(GGD) . The GGD is given by GG¾ X ¯ (x) = C(¾ X ¯ )exp¡ [® (¾ X ¯ )jxj]¯ (6) ¡ 1 < x < 1 ¯ > 0, where ® (¾ X ¯ ) = ¾ ¡ 1 X [ ¡ (3=¯ ) ¡ (1=¯ ) ]1=2 and C(¾ X ¯ ) = ¯ ¢ ® (¾ X ¯ ) 2¡ ( 1 ¯ ) and ¡ (t) = R1 0 e¡ uut¡ 1du. The parameter ¾ X is the standard deviation and ¯ is the shape parameter It has been observed[5] that with a shape parameter ¯ ranging from 0.5 to 1, we can describe the the distribution of coefficients in a subband for a large set of natural images.Assuming such a distribution for the wavelet coefficients, we empirically estimate ¯ and ¾ X for each subband and try to find the threshold T which minimizes the Bayesian Risk, i.e, the expected value of the mean square error.

matlab下可以直接使用的小程序 包括各种常用算法 对应书籍为《matlab宝典》 此为总的部分(matlab can be directly used for small programs include a variety of commonly used algorithms corresponding books as " matlab book" This is part of the total)

数独游戏的MATLAB实现！还能帮助玩家完成数独游戏。( SUDOKUE play sudoku with MATLAB (aids for solving included) A guide on how sudoku works can be found e.g. on http://en.wikipedia.org/wiki/Sudoku This program has a history-function, i.e. you can undo and redo each single step. You can also save and load a score including all settings (execpt for the branching solver). New games can be imported either as ASCII-string or from sdm- or sdk-files resprectively. Puzzles in ASCII-Format or as sdm- or sdk-file respectively can be found e.g. on http://www.sudocue.net)
