  abstract =     "this paper proposes new type of coding scheme, which
                 uses unidirectional transform, unlike conventional
                 image/video coding schemes such as JPEG, MPEG-2,
                 H.265/HEVC, whose encoder uses forward and inverse
                 transforms and decoder uses inverse transform. In our
                 proposal, even encoder (and decoder as well) uses
                 unidirectional (in conventional manner, inverse)
                 transform. Because of this preferable property, the
                 encoder can arbitrarily design nonlinear,
                 content-specific transforms, regardless of obtaining
                 its inverse transform, to optimize coding performance.
                 In our preliminary experiment, BD-Rate gain of 1.18
                 percent was observed against HEVC reference software
