matlab - How to implement a conditional random field based energy function from images? -
i trying implement segmentation tool images, , trying utilize conditional random field (crf) based method. example, in this paper.
the standard crf energy function includes 2 parts, i.e., unary potential , pairwise potential
where l class labels , x observations (image pixels).
i have got training image labels of objects in image. example, have got ground truth segmentation of objects in image labels.
if want utilize texture of these objects feature, wondering how implement , training of energy function? example, unary term can represented by
where v_texture vectorised texture feature of each labelled object.
my question how implement log probability function? using histogram? thanks. a.
