Perceptual transparency and robustness are conflicting requirements. To ensure the security of the watermarkhow to choose the embedding position and intensity is a difficult probl...
This paper presents an object tracking method for object-based video processing which uses a two-dimensional (2-D) Gabor wavelet transform (GWT) and a 2-D golden section algorithm....
Many applications in a variety of scientific domains produce datasets that consist of a data field lying on a sampling grid that may not be uniformly spaced. However, progressive ...
—The 2D Discrete Wavelet Transform (DWT) is a time-consuming kernel in many multimedia applications such as JPEG2000 and MPEG-4. The 2D DWT consists of horizontal filtering alon...
The discrete wavelet transform (DWT) is used in several image and video compression standards, in particular JPEG2000. A 2D DWT consists of horizontal filtering along the rows fo...
