A Framework of Secured Embedding Scheme Using Vector Discrete Wavelet Transformation and Lagrange Interpolation

Table 3

Comparison of the proposed and existing approaches.

Embedding techniques	Cover image	Payload	Average PSNR
Proposed method using VDWT	Extracted skin tone region	Handwritten document and logo	52.0325 (image 1 to image 4)
Horizontal band of DWT [23]	Standard database image like garden and house images	Ordinary image like cups and rose images	50.25
LSB method [24]	Standard image like cameraman image	Digital data	46.23
DCT-based method (hiding in LSB) [10]	Flower image	Text message	42
LSB with edge detection [11]	Edge-detected standard database image like Leena and Baboon image	Information as bit	37 to 43
LSB method [12]	Standard database image like Leena and Baboon image	Information as bit	47.23
