Frequency-tuned Salient Region Detection MATLAB代码出错修改方法

论文：Frequency-tuned Salient Region Detection.CVPR.2009

MATLAB代码运行出错如下：

Error using makecform>parseWPInput (line 389)
Expected input number 2, PROPERTYNAME, to match one of these strings:

AdaptedWhitePoint

The input, ''whitepoint'', did not match any of the valid strings.

Error in makecform>parseWPInputs (line 378)
wp = parseWPInput(varargin{2}, varargin{3}, valid_strings, 'WP', 2);

Error in makecform>make_srgb2lab_cform (line 349)
wp = parseWPInputs('AdaptedWhitePoint', varargin{:});

Error in makecform (line 213)
c = make_srgb2lab_cform(varargin{:});

Error in FT_Saliency_CVPR2009 (line 36)
cform = makecform('srgb2lab', 'whitepoint', whitepoint('d65'));

修改如下：

cform = makecform('srgb2lab', 'AdaptedWhitePoint', whitepoint('d65'));

% Please note that the saliency maps generated using this
% code may be slightly different from those of the paper.
% This seems to be because the RGB to Lab conversion is
% different from the one used for the results in the C++ code.
% The C++ code is available on the same page as this matlab
% code (http://ivrg.epfl.ch/supplementary_material/RK_CVPR09/index.html)
% One should preferably use the C++ as reference and use
% this matlab implementation mostly as proof of concept
% demo code.

% Read image and blur it with a 3x3 or 5x5 Gaussian filter
%---------------------------------------------------------
img = imread('100\images\8.jpg');%Provide input image path
gfrgb = imfilter(img, fspecial('gaussian', , ), 'symmetric', 'conv');
%symmetric图像大小通过镜像反射其边界来扩展 conv通过使用卷积来完成
%fspecial('gaussian', , )产生3*3高斯低通滤波器模板

% Perform sRGB to CIE Lab color space conversion (using D65)

%cform = makecform('srgb2lab', 'whitepoint', whitepoint('d65'));
cform = makecform('srgb2lab', 'AdaptedWhitePoint', whitepoint('d65'));

% Compute Lab average values (note that in the paper this
% average is found from the unblurred original image, but
% the results are quite similar)
%---------------------------------------------------------
l = double(lab(:,:,)); lm = mean(mean(l));
a = double(lab(:,:,)); am = mean(mean(a));
b = double(lab(:,:,)); bm = mean(mean(b));
%---------------------------------------------------------
% Finally compute the saliency map and display it.

sm = (l-lm).^ + (a-am).^ + (b-bm).^;
imshow(sm,[]);
