Dynamic systems can often be separated into fast and slow subsystems. The speed and accuracy of a simulation of such systems can frequently be improved by using a frame rate for numerical integration of the fast system which is an integer multiple of the frame rate used for the slow system. The technique of multiple frame-rate integration can be especially important in real-time simulation. In ...

The frame and field rates that have been used for television since the 1930s cause problems for motion portrayal, which are increasingly evident on the large, high-resolution television displays that are now common. In this paper we report on a programme of experimental work that successfully demonstrated the advantages of higher frame rate capture and display as a means of improving the qualit...

background: increasing frame rate is a challenging issue for better interpretation of medical images and diagnosis based on tracking the small transient motions of myocardium and valves in real time visualization. methods: in this paper, manifold learning algorithm is applied to extract the nonlinear embedded information about echocardiography images from the consecutive images in two dimension...

Perceptual indicators of multimedia quality have to be taken into account in order to build the truly end-toend communication architectures of the future. This paper investigates the perceptual impact of differing multimedia presentation frame rates on user information assimilation and level of satisfaction. We apply the Quality of Perception (QoP) concept, which encompasses not only a user’s a...

In this paper, we present an algorithm for doing high frame rate egomotion estimation. We achieve this by using a basis flow model, along with a novel inference algorithm, that uses spatio-temporal gradients, foregoing the computation of the slow and noisy optical flow. The inherent linearity in our model allows us to achieve fine grained parallelism. We demonstrate this by running our algorith...

This paper presents multi-frame rate volume rendering, an asynchronous approach to parallel volume rendering. The workload is distributed over multiple GPUs in such a way that the main display device can provide high frame rates and little latency to user input, while one or multiple backend GPUs asynchronously provide new views. The latency artifacts inherent to such a solution are minimized b...

Multi-frame rate systems decouple viewing from rendering in an asynchronous pipeline. Multiple GPUs can be used as frame sources, while a primary GPU is responsible for viewing and display update. Conventionally, the last rendering result is used for display. However, modern GPUs are equipped with a fairly large amount of memory which allows frames to be cached in video memory. As long as the d...

A novel rate control algorithm consisting of two major components , i.e. a variable encoding frame rate method and a hybrid DCT/wavelet I-frame coding scheme, is proposed in this work for low bit rate video coding. Most existing rate control algorithms for low bit rate video focus on bit allocation at the macroblock level under a constant frame rate assumption. The proposed rate control algorit...
