การถอดลายน้ำ โดยการแปลงกลับสัมประสิ

To remove the watermark by wavelet transformed coefficients (inverse discrete wavelet transform:.idwt) made to the discrete wavelet transform and embed watermark to return to its original shape. To create or restore the original input signal. By the various sub-components to the concatenation operator is the same as the original signal.

To remove a watermark using Discrete Inverse inverse Wavelet coefficients (the Tablet wave Transform: IDWT) to make a Discrete Wavelet Transform that and embed watermarks into images back to the original input signal returns to an original creation by bringing the various subassemblies into the original signal is identical to the original image.

To remove the watermark, convert back to abrasion resistance เวฟเล็ต (Inverse Discrete Wavelet Transform:IDWT) to make a watermark Discrete Wavelet Transform and flush down to come back to the original or to create original input signal returned by the Sub components, arranged in the same to the same as the original signal is original image
