Rate-Distortion Optimization Based on Two-Pass Encoding for HEVC
IEEE Access, 2021 Rate-distortion optimization (RDO) is a crucial technique in block-based hybrid video encoders, which determines the coding option for a certain coding unit to achieve optimal rate-distortion (R-D) performance.

Free constructions and coproducts of d-frames
CoRR, 2017 A general theory of presentations for d-frames does not yet exist. We review the difficulties and give sufficient conditions for when they can be overcome. As an application we prove that the category of d-frames is closed under coproducts.

Non-singular pre-big bang scenarios from all-order α′ corrections
Journal of High Energy Physics, 2023 We reformulate in Hamiltonian language the recent proposal by Hohm and Zwiebach of an action yielding the most general O(d, d)-symmetric string cosmology equations, at tree-level in the string-loop expansion, but to all orders in the α′ expansion.

Requirements and Hardware Limitations of High-Frame-Rate 3-D Ultrasound Imaging Systems
Applied Sciences, 2022 The spread of high frame rate and 3-D imaging techniques has raised pressing requirements for ultrasound systems. In particular, the processing power and data transfer rate requirements may be so demanding to hinder the real-time (RT) implementation of ...

Stellar Half-mass Radii of 0.5 z < 2.3 Galaxies: Comparison with JWST/NIRCam Half-light Radii
The Astrophysical Journal, 2023 We use CEERS JWST/NIRCam imaging to measure rest-frame near-IR light profiles of 435 M _⋆ > 10 ^10 M _⊙ galaxies in the redshift range of 0.5 < z < 2.3.

A Hybrid 3D Descriptor With Global Structural Frames and Local Signatures of Histograms
IEEE Access, 2018 An effective feature descriptor is important for the 3-D object recognition and reconstruction. This paper presents a novel 3-D Frame-signature of histograms of orientation (SHOT) descriptor which combines the global structural frame with local surface ...

IEEE Access, 2018 Motion estimation (ME) is a kernel algorithm in many video applications. Full search integer ME (FSIME) can find the best result but it usually takes plenty of time. Traditionally, only intra-frame data reuse is considered for FSIME. In this paper, a new
