In the past decade or so, subspace methods have been largely used in face recognition ? generally with quite success. Subspace approaches, however, generally assume the training d...
Abstract. We propose a brain-computer interface (BCI) system for evolving images in realtime based on subject feedback derived from electroencephalography (EEG). The goal of this s...
Abstract. In this paper, the security of Dither Modulation Quantization Index Modulation schemes for digital images is analyzed. Both pixel and DCT coefficient quantization schemes...
In this paper, a blind object-based video watermarking scheme, which is robust to MPEG4 compression and normal video editing such as Rotation, Scaling or Translation (RST), is pro...
— Non-negative Matrix factorization (NMF) has increasingly been used as a tool in signal processing in the last couple of years. NMF, like independent component analysis (ICA) is...
