5.A diagramming notation and specification tool that uses nested layers of brackets that represent the structure of thelogic used to transform input data into output data.
9.Many watermark embedding schemes in transform domain are proposed such as 2-D DFT,2-D DCT and 2-D DWT which are used to transform the image data,and 3-D DCT and 3-D DWT which are used to transform the video data and 3-D image data.
