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...

GF-3 SAR IMAGE DESPECKLING BASED ON THE IMPROVED NON-LOCAL MEANS USING NON-SUBSAMPLED SHEARLET TRANSFORM
GF-3 SAR non-subsampled Shearlet transform image despeckling improved Non-Local Means
2018/5/15
GF-3 synthetic aperture radar (SAR) images are rich in information and have obvious sparse features. However, the speckle appears in the GF-3 SAR images due to the coherent imaging system and it hinde...
Local Sequence Based Rendezvous Algorithms for Cognitive Radio Networks
Rendezvous Time to Rendezvous Local Se- quence
2016/1/22
Rendezvous process plays an important role in constructing Cognitive Radio Networks (CRNs), through which a user establishes a link on a common licensed channel for communication with its neighbors.

2015/6/26
In Space Based Augmentation Systems (SBAS), many reference receivers are placed throughout a large region, and their measurements are combined to create a set of corrections for each ranging satellite...
ALTERNATIVE METHODOLOGIES FOR THE ESTIMATION OF LOCAL POINT DENSITY INDEX: MOVING TOWARDS ADAPTIVE LIDAR DATA PROCESSING
LIDAR Point cloud Processing Estimation Quality Analysis
2014/4/28
Over the past few years, LiDAR systems have been established as a leading technology for the acquisition of high density point clouds over physical surfaces. These point clouds will be processed for t...
An O(log n) Distributed Approximation Algorithm for Local Broadcasting in Unstructured Wireless Networks
Local Broadcasting Unstructured Wireless Networks
2012/12/4
The unstructured multi-hop radio network model, with asynchronous wake-up, no collision detection and little knowledge on the network topology, is proposed for capturing the particularly harsh charact...
