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...
Subsampling is a commonly used technique for modern image and video compression. Existing image and video standards such as JPEG, MPEG, and H.264 provide support for uniform chrom...
A novel algorithm is described for coding objects in video compression systems which gives complete control over the bit allocation to the video objects. The method is evaluated b...
The performance of many computer vision and machine learning algorithms critically depends on the quality of the similarity measure defined over the feature space. Previous works...
The performance of many supervised and unsupervised learning algorithms is very sensitive to the choice of an appropriate distance metric. Previous work in metric learning and ada...
