Graphons are infinite-dimensional objects that represent the limit of convergent sequences graphs as their number nodes goes to infinity. This paper derives a theory graphon signal processing centered on notions Fourier transform and linear shift invariant filters, counterparts graph filters. It is shown for associated signals: (i) converges when bandlimited; (ii) spectral vertex responses filt...

Thispaper reviews computational techniques to efficiently represent, analyse and visualise both shortterm and long-term temporal variation in video and image sequences. This paper reveals temporal variation in videos that are imperceptible to the naked eye. The method takes a standard video sequence as an input, and applies spatial decomposition, followed by temporal filtering to the frames whi...

Recently digital signal processing has become very popular in video signal processing systems. Analog-toDigital (A/D) converters in this field, namely, video A/D converters, are also popular and have been integrated into mixed-signal system LSIs. Both power consumption and power supply voltage of video A/D converters have been decreasing drastically in recent years [1], [2]. One of the applicat...

Content distribution applications such as digital broadcasting, video-on-demand services, video conferencing, surveillance, and telesurgery are confronted with difficulties besides the inevitable compression and quality challenges with respect to intellectual property management, authenticity, privacy regulations, and access control. Meeting such security requirements in an end-to-end video dis...

This paper presents a color-resolution layered coding scheme for a scalable video delivery system which operates over heterogeneous networks and distributes real-time streaming video to diverse types of video clients running on devices which range from high-powered workstations to mobile computing devices such as handheld and palm-sized computers. The layered coding scheme employs a wavelet tra...
