Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：An active contour model with local variance force term and its efficient minimization solver for multi-phase image
局部方差力项 活动轮廓模型 多相图像 最小化求解器
2023/5/8
In this work, we propose an active contour model with a local variance force (LVF) term that can be applied to multi-phase image segmentation problems. With the LVF, the proposed model is very effecti...
A new X-ray technique developed at Cornell offers an unprecedented look at the elaborate inner workings of batteries while they are in use – a breakthrough that is already yielding important findings ...

Branching in woody plants affects their ecological benefits and impacts wood formation. To obtain genome-wide insights into the transcriptome changes and regulatory mechanisms associated with branchin...
Comparison of diferent aroma active compounds of Sichuan Dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea using gas chromatography–mass spectrometry (GC–MS) and aroma descriptive profle tests
aroma active compounds Sichuan Dark brick tea Sichuan Fuzhuan brick tea GC–MS aroma descriptive profle tests
2024/7/31
Sichuan dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea have signifcantly diferent aroma characteristics although both of them have almost the same processing methods. Thus, these two...
A Quantum-Proof Non-Malleable Extractor With Application to Privacy Amplification against Active Quantum Adversaries
Privacy Amplification Non-malleable extractors Quantum Cryptography
2019/3/1
privacy amplification, two mutually trusted parties aim to amplify the secrecy of an initial shared secret X in order to establish a shared private key K by exchanging messages over an insecure commun...
MArBled Circuits: Mixing Arithmetic and Boolean Circuits with Active Security
MPC Garbled Circuits Secret Sharing
2019/3/1
There are two main ways of performing computation on private data: one method uses linear secret-sharing, in which additions require no communication and multiplications require two secrets to be broa...
HIGH-RESOLUTION ENHANCED PRODUCT BASED ON SMAP ACTIVE-PASSIVE APPROACH USING SENTINEL 1A AND 1B SAR DATA
soil moisture microwave remote sensing active-passive algorithm SMAP Sentinel-1A -1B
2019/2/27
SMAP project released a new enhanced high-resolution (3km) soil moisture active-passive product. This product is obtained by combining the SMAP radiometer data and the Sentinel-1A and -1B Synthetic Ap...
Concretely Efficient Large-Scale MPC with Active Security (or, TinyKeys for TinyOT)
MPC large scale concrete efficiency
2018/11/16
In this work we develop a new theory for concretely efficient, large-scale MPC with active security. Current practical techniques are mostly in the strong setting of all-but-one corruptions, which lea...
Computer-aided proofs for multiparty computation with active security
formal verification secure multiparty computation
2018/5/28
Secure multi-party computation (MPC) is a general cryptographic technique that allows distrusting parties to compute a function of their individual inputs, while only revealing the output of the funct...
AIRCRAFT SEGMENTATION IN SAR IMAGES BASED ON IMPROVED ACTIVE SHAPE MODEL
SAR target segmentation aircraft ISOMAP
2018/5/16
In SAR image interpretation, aircrafts are the important targets arousing much attention. However, it is far from easy to segment an aircraft from the background completely and precisely in SAR images...
