  • 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.
