Abstract Four-dimensional (4D) printing is an advanced manufacturing technology that has rapidly emerged as a transformative tool with the capacity to reshape various research domains and industries. Distinguished by its integration of time dimension, 4D allows objects dynamically respond external stimuli, setting it apart from conventional 3D printing. This roadmap been devised, contributions 44 active researchers in this field 32 affiliations world-wide, navigate swiftly evolving landscape...
Head-mounted display (HMD) has been widely used in many fields, and most existing HMDs are complex typically non-aesthetically pleasing. In this paper, a novel compact, lightweight wearable off-axis HMD with freeform surface is reported. It challenging to achieve large field of view (FOV) maintain compact structure simultaneously for type system. design, the consists tilted ellipsoid combiner four pieces relay lenses. offers diagonal FOV 30°, an exit pupil diameter 7 mm. No diffractive...
Studies on human motion have attracted a lot of attentions. Human capture data, which much more precisely records than videos do, has been widely used in many areas. Motion segmentation is an indispensable step for related applications, but current methods data do not effectively model some important characteristics such as Riemannian manifold structure and containing non-Gaussian noise. In this paper, we convert the into temporal subspace clustering problem. Under framework sparse...
Human motion capture data has been widely used in many areas, but it involves a complex process and the captured inevitably contains missing due to occlusions caused by actor's body or clothing. Motion recovery, which aims recover underlying complete sequence from its degraded observation, still remains as challenging task nonlinear structure kinematics property embedded data. Low-rank matrix completion-based methods have shown promising performance short-time-missing recovery problems....
By analyzing the selection and application of policy instruments in construction close-knit county medical communities Dazu District, Chongqing, this study aimed to propose countermeasures optimize these instruments, offering valuable lessons for communities. Based on Hood's classification, an analytical framework was constructed that incorporated basic (X dimension) different phases process (Y dimension). Nvivo used analyze documents (2015-2023) related District. In X dimension,...
Human motion capture data, which are used to animate animation characters, have been widely in many areas. To satisfy the high-precision requirement, human data captured with a high frequency (120 frames/s) by system. However, and nonlinear structure make storage, retrieval, browsing of challenging problems, can be solved keyframe extraction. Current extraction methods do not properly model two important characteristics i.e., sparseness Riemannian manifold structure. Therefore, we propose...
This paper introduced a way to implement 3D WebGIS system which was based on WebGL technology. The used Ellipsoidal Mercator projection and WGS84 coordinates, made JSON file format for network transformation, described popular method tile map service, finished prototype of WebGIS. applied in Remote Sensing Catalogue Service system. At last the discussed what's good bad aspects WebGL.
Recently, sparse representation-based classification (SRC) has been widely studied and produced state-of-the-art results in various tasks. Learning useful computationally convenient representations from complex redundant highly variable visual data is crucial for the success of SRC. However, how to find best feature representation work with SRC remains an open question. In this paper, we present a novel discriminative projection learning approach objective seeking matrix such that learned...
A double-channel prism imaging spectrometer that includes visible-near-infrared (VNIR) and shortwave-infrared (SWIR) spectra is presented. Double slits divide a wide spectral band into two independent channels for VNIR SWIR, guaranteeing their resolution. beam splitter splits the two, one detected by SWIR other detector. The freeform surface, as mirror, compensates astigmatism across band. An with 30° field of view measured spectrum from 400 nm to 2500 designed. This compact, cost-effective...
