This paper proposes a reversible data hiding method for error diffused halftone images. It employs statistics feature of pixel block patterns to embed data, and utilizes the HVS ch...
Recently we have applied Look Up Table (LUT) Method for inverse halftoning. We also proposed tree-structure LUT inverse halftoning in order to reduce memory requirements of the LU...
1 Recently the authors proposed a Look Up Table (LUT) based method for inverse halftoning of images. The LUT for inverse halftoning is obtained from the histogram gathered from a f...
