redisplay.m

cootes提出的ASM算法的matlab实现。在cootes用于课堂使用的源代码的基础上改写。改正了原来代码中的一些错误

function redisplay;
% Redisplay things when slider values are changed

% WhatToRedisplay specifies a three nb vector 
% [1 0 0] to repaint only axes X
% and so on. To avoid working too much

% Must be issued in all functions using the global variable
global allslices;

[xs,ys,zs]=size(allslices);

% Get the handle of the figure
figure(findobj('Tag','Mainfig'))

% The slider does not come with integer values, so fetch them to integers
val_x = ceil(get(findobj('Tag','slider_X'),'Value')-0.5);
val_y = ceil(get(findobj('Tag','slider_Y'),'Value')-0.5);
val_z = ceil(get(findobj('Tag','slider_Z'),'Value')-0.5);

% Draw the right slice at the right place
% and with pretty yellow lines showing where we are
