This package contains an implementation of the matting algorithm described inthe CVPR2006 paper:"A Closed Form Solution to Natural Image Matting" . To run the matting algorithm, use the runMatting script. The scripts runMatting_*.m are example scripts, calling runMatting on the images used in the paper.simple examples to start with, could be:runMatting_Kid2.m, runMatting_Hair.m, runMatting_Dandelion.m. The runMatting script uses the arguments described below.Input arguments:img_name - input image filescribs_img_name - input image with black&white scribbles.Note that since the code uses a simple diff to find the scribbled pixels, you should not place scribbles with fuzzy boundaries. Photoshop users- use pencil tool, hard brushes.Output arguments:alpha, F,B - representing the alpha matte and the estimation of foreground and background colors.Additional (optional) input arguments: (if you don't define them a default value will be used epsilon regularization term (see eq 3 in the paper).The default value is epsilon=0.1^7. For jpeg or noisy images use epsilon=0.1^5.win_size - size of the windows in which the linear model is used (default is 3x3 windows). For running matting using multi resolutions:levels_num - number of levels to useactive_levels_num -use active_levels_num<=levels_num.If active_levels_num
