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'));
