Abstract: The present invention provides an efficient hardware guided filtering method for use in solving a multi-label problem. The method includes the following steps: inputting an input guidance of a multi-label image; defining an efficient hardware guided filtering (HGF) model; calculating a vector by a customized matrix inversion operation; inputting guidance through a mapping program for adding up result of each channel to form a polynomial guidance, and introducing nonlinearity into the linear model; and obtaining a filtering result in an efficient hardware mode by element-wise calculation and box filtering.
