Application of 1-D filters to image transmultiplexing

Several images are combined into one image for transmission by a single channel and recovery by a receiver. The distortion or mixture of the received images is invisible. Transmultiplexer consists of upsamplers and 1-D FIR filters. Detransmultiplexer consists of 1-D FIR filters and downsamplers. Bilinear constraints on the synthesis and analysis FIR filters are imposed to achieve the perfect reconstruction. The optimization method for filter design was applied.
