Image Watermarking Using All Phase Discrete Cosine Biorthogonal Transform in Selected Pixel Blocks

In the past decade, a transform called all phase discrete cosine biorthogonal transform (APDCBT) appeared in the field of digital image processing. It is mainly used to solve the negativity found in discrete cosine transform (DCT), especially in a low bit rate. In this paper, the APDCBT is employed...
