In this paper, we propose a new real transform (rCS-SCHT) derived from the conjugate symmetric sequencyordered complex Hadamard transform (CS-SCHT) for document image compression. Like the CS-SCHT, the proposed transform is also an orthogonal transform. The transform computation is very simple and i...
