Motion description of objects time evolution is often bit-rate wasting even if computed at a low fixed ffame rate. Bit-rate reduction can be achieved taking advantage of the inactivity periods: in such time intervals there is no need for motion coding, as an accurate description of the scene can be obtained only considering the frame diflerence information. We propose to estimate the motion bet...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

in this paper the author considers a general method, based on time domain samples for spectral manipulation of time limited signals. first, the original signal is divided into some frames in the time domain. then, by presenting a suitable theoretical and computational algorithm, and using a method for improving the speed of convergence, we find the local bandwidth of each frame; thereby, each f...

Object tracking is commonly used in video surveillance, but typically video with full frame rate is sent. We previously have shown that full frame rate is not needed, but it is unclear what the appropriate frame rate to send or whether we can further reduce the frame rate. This paper answers these questions for two commonly used object tracking algorithms (frame-differencing-based blob tracking...

In this article, we propose a new frame rate up-conversion (FRU) method for temporal quality enhancement. The proposed FRU algorithm employs gradual and adaptive motion estimation based on confidence priority for selecting more accurate motion vectors (MVs). In order to estimate accurate MVs, we adaptively alternate a search range and the order of blocks to be searched depending on the confiden...

Streaming of precoded video, which is both sourceand channelcoded, over packet-loss networks faces challenges of the timevarying packet loss rate and fluctuating bandwidth. Rate shaping has been proposed to reduce the bit rate of a precoded video bitstream to adapt to the real-time bandwidth variation. In our earlier work, rate shaping was extended to consider not only the bandwidth but also th...

Time management (or frame rate control) is the backbone system that feedbacks on a number of game engine modules to provide physically correct, interactive, stable and consistent graphics output. This paper discusses time related issues in game engines and proposes a unified time management (or more specifically frame rate control) architecture, which can be easily applied to existing game engi...

Cascades help make sliding window object detection fast, nevertheless, computational demands remain prohibitive for numerous applications. Currently, evaluation of adjacent windows proceeds independently; this is suboptimal as detector responses at nearby locations and scales are correlated. We propose to exploit these correlations by tightly coupling detector evaluation of nearby windows. We i...

Recently neural network acoustic models trained with Connectionist Temporal Classification (CTC) were proposed as an alternative approach to conventional cross-entropy trained neural network acoustic models which output frame-level decisions every 10ms [1]. As opposed to conventional models, CTC learns an alignment jointly with the acoustic model, and outputs a blank symbol in addition to the r...
