(1) Addition, subtraction, multiplication, and division are binary operations.

(2) Groups just have one binary operation.

(3) DoOp Performs the specified binary operation on the specified numeric operands.

(4) The improved binary operation methods was utilized, and watermarks are embedded to the low frequency coefficients of deep wavelet domain.

(5) Computer using binary, because the rules of simple binary operation, and easy to achieve in physics.

(6) The second applies a binary operation to pairs of elements.

(7) As a result, the proposed method avoids the binary operation used in some traditional Chinese character feature extractions that will seriously destroy the Chinese character structure.

(8) Then, the watermarks are embedded into the wavelet coefficients by using the improved binary operation methods.

(9) In current computer application, use most is the 0 binary operation mode with 1 composition.

(10) This algorithm scans the data base only once and the speed of binary operation is faster than the speed of comparison of item sets and transactions.

(11) A new algorithm for digital image watermarking based on binary operation in the wavelet transform domain is proposed, and the original image is not required for detecting the watermark.
