Abstract
The present disclosure provides a method for converting a Two-Dimensional image into a Three-Dimensional image, comprising: obtaining high-frequency components and low-frequency component of the current frame, and high-frequency components of the reference frame; establishing triangular geometric models in the three directions of horizontal, vertical and diagonal, respectively; performing a motion search on the high-frequency components of the reference frame in the three directions of horizontal, vertical and diagonal, respectively, so as to obtain motion vectors in the corresponding directions, and calculating depth variations of the corresponding directions according to the motion vectors in the corresponding directions; performing an interpolating operation on the triangular geometric models in the three directions of horizontal, vertical and diagonal, respectively, according to the depth variations in the corresponding directions, so as to obtain high-frequency depth graphs in the corresponding directions; and completing a filtering reconstruction by performing an inversion wavelet transform on the high-frequency depth graphs in the three directions of horizontal, vertical and…
