VTNCT: an image-based virtual try-on network by combining feature with pixel transformation
The Visual Computer - Tập 39 Số 7 - Trang 2583-2596 - 2023
Image-based virtual try-on tasks with the goal of transferring a target clothing item onto the corresponding region of a person have attracted increasing research attention recently. However, most of the existing image-based virtual try-on methods have a shortcoming in detail generation and preservation. To resolve these issues, we propose a novel virtual try-on network to generate photo-realistic......
R-LODs: fast LOD-based ray tracing of massive models
The Visual Computer - Tập 22 - Trang 772-784 - 2006
We present a novel LOD (level-of-detail) algorithm to accelerate ray tracing of massive models. Our approach computes drastic simplifications of the model and the LODs are well integrated with the kd-tree data structure. We introduce a simple and efficient LOD metric to bound the error for primary and secondary rays. The LOD representation has small runtime overhead and our algorithm can be combin......
Harris 3D: a robust extension of the Harris operator for interest point detection on 3D meshes
The Visual Computer - Tập 27 - Trang 963-976 - 2011
With the increasing amount of 3D data and the ability of capture devices to produce low-cost multimedia data, the capability to select relevant information has become an interesting research field. In 3D objects, the aim is to detect a few salient structures which can be used, instead of the whole object, for applications like object registration, retrieval, and mesh simplification. In this paper,......
Photon mapping with visible kernel domains
The Visual Computer - Tập 35 - Trang 707-720 - 2018
Despite the strong efforts made in the last three decades, lighting simulation systems still remain prone to various types of imprecisions. This paper specifically tackles the problem of biases due to density estimation used in photon mapping approaches. We study the fundamental aspects of density estimation and exhibit the need for handling visibility in the early stage of the kernel domain defin......
Two-stage multi-view deep network for 3D human pose reconstruction using images and its 2D joint heatmaps through enhanced stack-hourglass approach
The Visual Computer - Tập 38 - Trang 2417-2430 - 2021
Human beings easily reconstruct the 3D pose of a human from a 2D image, but 3D human pose reconstruction (HPR) continues to exist as a challenging task for machines. Traditional methods can reconstruct the 3D pose from the image directly or from the 2D joint locations that have been used for 3D HPR. Such traditional strategies have their merits and demerits. In this paper, we have tried to combine......
Dynamic time warping similarity measurement based on low-rank sparse representation
The Visual Computer - Tập 38 Số 5 - Trang 1731-1740 - 2022
Dynamic stills and clip trailers
The Visual Computer - Tập 22 - Trang 642-652 - 2006
We propose a method for generating visual summaries of video. It reduces browsing time, minimizes screen-space utilization, while preserving the crux of the video content and the sensation of motion. The outputs are images or short clips, denoted as dynamic stills or clip trailers, respectively. The method selects informative poses out of extracted video objects. Optimal rotations and transparency......
A robust framework for spoofing detection in faces using deep learning
The Visual Computer - Tập 38 - Trang 2461-2472 - 2021
Face recognition is used in biometric systems to verify and authenticate an individual. However, most face authentication systems are prone to spoofing attacks such as replay attacks, attacks using 3D masks etc. Thus, the importance of face anti-spoofing algorithms is becoming essential in these systems. Recently, deep learning has emerged and achieved excellent results in challenging tasks relate......
New grouping and fitting methods for interactive overtraced sketches
The Visual Computer - Tập 30 - Trang 285-297 - 2013
This paper describes a new method for recognizing overtraced strokes to 2D geometric primitives, which are further interpreted as 2D line drawings. This method can support rapid grouping and fitting of overtraced polylines or conic curves based on the classified characteristics of each stroke during its preprocessing stage. The orientation and its endpoints of a classified stroke are used in the s......
