The file "imgfeature.txt" contains the images and their features. One line is for a image. And the pattern is:
imgId,saturation,sat_con,bright,bright_con,dull_color_ratio,cool_color_ratio,fg_color_dif,fg_area_dif,fg_texture_src,fg_texture_sal,c1_h,c1_s,c1_v,c2_h,c2_s,c2_v,c3_h,c3_s,c3_v,c4_h,c4_s,c4_v,c5_h,c5_s,c5_v. And the "," is the separator.
for example, there is a line for a image:
means:imgId is 11932, saturation is 0.199045，sat_con is 0.125428，bright is 0.46487，bright_con is 0.237395，dull_color_ratio is 0.2564，cool_color_ratio is 0.45，fg_color_dif is 0.665636，fg_area_dif is 0.206533，fg_texture_src is 0.0614667，fg_texture_sal is 0.0252366，c1_h is 0.030303030303030304，c1_s is 0.3142857142857143，c1_v is 0.13725490196078433，c2_h is 0.09420289855072463，c2_s is 0.19166666666666668，c2_v is 0.47058823529411764，c3_h is 0.06666666666666667，c3_s is 0.18518518518518517，c3_v is 0.3176470588235294，c4_h is 0.0，c4_s is 0.039647577092511016，c4_v is 0.8901960784313725，c5_h is 0.6458333333333334，c5_s is 0.045714285714285714，c5_v is 0.6862745098039216.
