Enabling high frame-rate UHD real-time communication with frame-skipping
Proceedings of the 3rd ACM Workshop on Hot Topics in Video Analytics and Intelligent Edges, 2021With a high frame-rate and high bit-rate, ultra-high definition (UHD) real-time communication (RTC) users could sometimes suffer from severe service degradation. Due to the fluctuations of frames incoming and decoding at the client side, a decoder queue could be formulated before the streaming decoder at the client side. Those fluctuations could easily

Improved High Frame Rate Speckle Tracking for Echocardiography
2021High frame rate (HFR) speckle tracking echocardiography (STE) assesses myocardial function by quantifying motion and deformation at high temporal resolution. Our lab recently proposed a two-step HFR STE methodology based on 1-D cross-correlation [1].

IEEE Transactions on Circuits and Systems for Video Technology, 2007 在視訊壓縮應用中，常因為頻寬的限制必需對於視訊資料在空間或是時間的解析度上有所犧牲。利用降低框速(frame rate)所節省的資料率(bitrate)來維持在空間解析度上的一定畫質，以便於之後利用影像在時間上的關聯性來重建完整的框速；此種節省資料率(bitrate)的方式遠比保留多張畫質不好的畫框(frame)來得有效率。框速轉換(Frame Rate Up-conversion)的應用不僅適用於視訊會議上的壓縮，同時對於慢動作播放特效的需求或是不同播放規格之間的轉換(ex: NTSC vs. PAL)

Frame detection in high bit-rate CMOS systems
ICECS 2000. 7th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.00EX445), 2002This paper presents a technique for frame synchronization in high-speed telecommunications systems. The described structure allows frame synchronization to be performed independently from the technology inherent delays, resorting to a parallel data pattern detector and a bit alignment shifter.

Adaptive temporal filter for high frame-rate video
2010 IEEE International Conference on Multimedia and Expo, 2010Conventionally, generation methods for the input sequences of a video encoder have been independent from its following encoding process. In other words, such generation method has not been designed in terms of improving coding efficiency, although encoder optimization and pre-filter design have been studied in order to improve coding efficiency ...

Effects of phase aberration on high frame rate imaging
Ultrasound in Medicine & Biology, 2000A high frame-rate (HFR) imaging method (about 3750 frames/s for imaging of biological soft tissues at a depth of 200 mm) has been developed recently with limited diffraction beams. This method uses the fast Fourier transform (FFT) and inverse fast Fourier transform (IFFT) to construct images, and can be implemented with simple and inexpensive hardware,

A General Model of High Frame Rate Imaging System
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005A kind of high frame rate (HFR) 2D and 3D imaging method was developed in 1997. Because only one transmission is required to construct an image, this method can reach an ultra high frame rate (about 3750 volumes or frames per second for biological soft tissues at a depth of 200 mm).

A new metric for judder in high frame-rate video
2016 IEEE International Conference on Image Processing (ICIP), 2016Recent advances on high frame-rate (HFR) hold-type display systems have resulted in the increased demands for HFR contents. Frame-rate up conversion (FRUC) technique could be used for creating HFR contents from the existing low frame-rate (LFR) contents. However, the judder artifacts caused by FRUC would degrade the quality of HFR. The aim of this work

Motion Artifacts of Extended High Frame Rate Imaging
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007Based on the high frame rate (HFR) imaging method developed in our lab, an extended high frame rate imaging method with various transmission schemes was developed recently. In this method, multiple, limited-diffraction array beams or steered plane wave transmissions are used to increase image resolution and field of view as well as to reduce sidelobes.
