viola_jones 的haar 特征检测的matlab 程序

有关haar特征检测的MATLAB程序，是对应viola_jonesde 的文献的

function dispimg（img）
% displays an intensity image （on any intensity scale） using a gray-scale colormap
% with 256 colors. The intensity data are scaled to use the full colormap i.e.
% the darkest pixel is mapped to 1 and the brightest to 256

% first create a temporary image which maps the darkest pixel to
% 1 and the brightest pixel to 256 using the utility function scale.m
y = scale（img-InfInf1256）;

% now plot the image.....
%figure;   
image（y）;
colormap（gray（256））;
axis（‘off‘）;
