In this paper, an algorithm of time-distributed fast Fourier transform and inverse fast Fourier transform (TD-FFT/TD-IFFT) is proposed. This work is motivated by the needs to implement FFT/IFFT in real-time on general microprocessors (e.g., Intel's ×86-based microprocessors) in signal processing and control applications, for example, in real-time implementation of frequency-domain iterative learning...
With the increasing requirement of efficient image retargeting, many algorithms have been proposed for adapting images contents to various display settings. However, most of these algorithms work in spatial domain of raw images. Since images are mostly stored in DCT-based compressed format such as JPEG, it will be very attractive to realize the image retargeting in compressed domain. In this paper,...
Rate control plays a significant role for high quality video coding. This paper presents a rate control method for H.264/AVC, using a new bit allocation scheme for both I-frame and P-frame. This scheme is based on our proposed frame complexity measurement and estimation model. The measurement model considers not only the absolute complexity of I-frame and P-frame, respectively, but also the complexity...
Rate control plays a significant role for high quality video coding. This paper presents a rate control method for H.264/AVC using a new bit allocation scheme for P-frame. This scheme is based on our proposed P-frame complexity measurement and estimation model. The measurement model considers not only the absolute complexity of the picture via average gradient, but also the relative histogram difference...
Publish/subscribe paradigm is seen as a good candidate in constructing distributed applications due to its unique and powerful features such as anonymity, asynchrony and many-to-many communication. As applications based on publish/subscribe increases greatly it is required to support different quality of service properties. However, most current solutions adopt simple matching strategies without distinguishing...
