showtefim.m

加州大学伯克利分校的一个车俩识别程序, 用matlab实现

function showTefim(tefim, im, fignum, rect)
  acm = [0.5+cos(linspace(0,2*pi,256))'/2 0.5+sin(linspace(0,2*pi,256))'/2 ...
	 0.5-cos(linspace(0,2*pi,256))'/2];
  
  if(nargin>2)
    figure(fignum);
  end
  colormap(acm);
  
  if (nargin<4)
    if(nargin>1)
      subplot(2,2,1);
      imagesc(im); axis image;
    end
    
    subplot(2,2,2);
    imagesc(tefim(:,:,1).*(tefim(:,:,2)>0.02)); axis image; colorbar;
