A new multi-scale topology optimization framework for optimal combinations of macro-layouts and local gradings of TPMS-based lattice structures

Mechanics based design of structures and machines, 2022
In this work, optimal combinations of macro-layouts and local gradings of triply periodic minimal surface (TPMS)-based lattice structures are obtained by using multi-scale topology optimization. A new innovative framework is proposed by using two density

Optimization-Based Multi-scale Texture Synthesis

2011 10th International Symposium on Distributed Computing and Applications to Business, Engineering and Science, 2011
Multi-scale texture synthesis is a rising research in recent years. There are two shortcomings: First, the exemplar design is very difficult, Second, Multi-scale texture synthesis uses pixel matching. Pixel matching can not capture the big structure information of the texture and it requires significant resources.

Batch Bayesian optimization using multi-scale search

Knowledge-Based Systems, 2020
Abstract Hyperparameters are crucial to many machine learning algorithms. Conventional methods like grid search can be expensive when tuning hyperparameters of a complex model, for example, deep neural networks. Recently, Bayesian optimization has become popular in the machine learning community as an efficient tool for tuning hyperparameters ...

Workspace optimization for multi-scale micromanipulation system

2010 International Symposium on Micro-NanoMechatronics and Human Science, 2010
In the recent years, the demand for micro and nano motion devices has increased in many industrial applications such as assembling micro machines, manipulating biological cells, and micro-surgical operations like neurosurgery and ophthalmology. As a result, there is an urgent need to develop micro-nano manipulators capable of performing very small ...

Video retargeting with multi-scale trajectory optimization

Proceedings of the international conference on Multimedia information retrieval, 2010
Mobile devices are increasingly powerful in media storage and rendering. The prevalent request of decent video browsing on mobile devices is demanding. However, one limitation comes from the size and aspect constraints of display. To display a video on a small screen, rendering process probably undergoes a sort of retargeting to fit into the target ...

Low-Light Image Enhancement With Multi-Scale Attention and Frequency-Domain Optimization

IEEE transactions on circuits and systems for video technology (Print)
Low-light image enhancement aims to improve the perceptual quality of images captured in conditions of insufficient illumination. However, such images are often characterized by low visibility and noise, making the task challenging. Recently, significant

Geometry Guided Multi-Scale Depth Map Fusion via Graph Optimization

IEEE Transactions on Image Processing, 2017
In depth discontinuous and untextured regions, depth maps created by multiple view stereopsis are with heavy noises, but existing depth map fusion methods cannot handle it explicitly. To tackle the problem, two novel strategies are proposed: 1) a more discriminative fusion method, which is based on geometry consistency, measuring the consistency, and ...

Multi-Scale Hierarchical Topology Optimization for Nanophotonic Design

OSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF), 2020
We develop a multi-scale method to rapidly design efficient and fabrication-compatible nanophotonic devices, and demonstrate it by designing a mode multiplexer with 98.1% efficiency in 104 iterations under 50 seconds using 16 cores.
