The paper is devoted to modeling of single-layer garments as developable median surfaces, modeled in the form of a thin supple shell. The products are modeled in Maple 9.5 and Embarcadero RAD Studio. The modelling of conical skirts considering seams is performed to demonstrate the space form of garments in the gravity field of elastic materials. Also the product aeroman is modelled which brings the...
There has been significant work on learning realistic, articulated, 3D models of the human body. In contrast, there are few such models of animals, despite many applications. The main challenge is that animals are much less cooperative than humans. The best human body models are learned from thousands of 3D scans of people in specific poses, which is infeasible with live animals. Consequently, we...
The rapid growth of 3D model resources for 3D printing has created an urgent need for 3D model retrieval systems. Benefiting from the evolution of hardware devices, visualized 3D models can be easily rendered using a tablet computer or handheld mobile device. In this paper, we present a novel 3D model retrieval method involving view-based features and deep learning. Because 2D images are highly distinguishable,...
Soft tissue deformation is an important part of virtual surgery simulation systems. Real-time and realistic simulation of soft tissue deformation in humans is crucial for virtual surgery simulation systems. Soft tissue deformation simulation mainly applies a linear and viscoelastic biomechanical model, however, this model loses numerous properties of soft tissue. As a consequence, a realistic representation...
In this paper we present a method of human body reshaping which is based on 2D images. We first reshape a 3D human body from a 2D image by changing the 3D morphable circles in the 3D human body model, and then project the 3D model onto the original 2D plane. There are three main steps in our method. First, we can acquire the human body contour and the limbs information through the marks which were...
Good estimations of volume and surface area are important to biological systems measurement. In this paper we develop a 3D reconstruction from evenly sampled axial views in order to enable the volume and surface area measurement. We develop this system for high throughput applications with the zebrafish model system. The VAST BioImager is specifically developed for this purpose and with this system...
The present paper is concerned with study of the effects of different characteristics of the corneoscleral shell of the human eye on intraocular pressure (IOP) changes after intravitreal injections. Sensitivity analysis was performed to quantify the relative importance of material and geometrical parameters of the eyeball on the IOP elevation.
In the paper we present an efficient technique for parameterized human body model, which not only utilizes the proportional transformation as most of the previous work have done, but also concentrates on partial transformation about critical parts. Based on the standard template model, various body sizes can be generated by changing of feature parameters. Moreover, we employed physic characteristics...
We present a framework for a virtual try-on system. Starting with a template human body mesh, we reshape it to acquire meshes of various body dimensions according to the user specified parameters. These reshaped bodies are further processed in two directions: refitting a garment model to the outside of the body and embedding a skeleton to the inside. The refitted garment mesh is then bound to the...
We introduce a morph able template for dressed human modeling, called Morph able Dressed Human (MDH) template. The template is obtained by learning basic functions from two common types of clothes (long shirts and trousers) and defining a deform-combine manipulation. Our MDH template is parametric, spans variation in both clothes and body/pose, and can generate various dressed human shapes. The template...
There is an increasing number of students using tablets in schools. Mobile devices gained popularity as an educational tool and there are many schools that use them frequently in educational activities to improve learning. We found that first year students of mechanical engineering in general have difficulties in understanding 3D shapes from 2D views. There are many Augmented Reality (AR) applications...
This paper describes a new, open-source Matlab toolbox, which can be used to directly build realistic, complex geometrical models of irregular biological cell shapes and organelles based on user definitions on single two-dimensional micrographs. The main advantages are flexibility and versatility as needed for irregular cell shape modeling for computational bioelectrical and biomechanical studies,...
While single-view human action recognition has attracted considerable research study in the last three decades, multi-view action recognition is, still, a less exploited field. This paper provides a comprehensive survey of multi-view human action recognition approaches. The approaches are reviewed following an application-based categorization: methods are categorized based on their ability to operate...
Three-dimensional models of fingerprints obtained from contactless acquisitions have the advantages of reducing the distortion present in traditional contact-based samples and the effects of dirt on the finger and the sensor surface. Moreover, they permit to use a greater area for the biometric recognition.
Interactive robots are required to have minimal footprint on the shop floor and to be able to work in constrained areas while ensuring the safety of the humans. To this end, modeling of an unstructured environment including the humans is an indispensable part of the online control schemes deployed in such robots. In this regard, a new approach is proposed for generating an efficient model of the human...
Wormholes are the main characteristic shapes resulting from the carbonate reservoir acidizing. Understanding wormhole patterns can determine the success of acidizing to a large extent. Due to various influences, such as the reaction rate between the acid and rock, and anisotropy of formation, the shapes of wormholes are quite complex and stochastic. So simulating the wormholes by traditional methods...
This paper presents a method permitting to determine the relationship between body measurements and human perception on morphology of body shapes, expressed by a set of emotional descriptors and fashion themes. It can be integrated into current garment CAD system for providing personalized design support. Two procedures of sensory evaluation have been used. The first one aims at evaluating abstract...
The example-based method for generating realistic, controllable human models was presented. Users are assisted in automatically generating modifying an example body data by controlling the parameters provided. The examples from the Poser and 3D Max is preprocessed as templates. The modeling method learns from these examples the correlation between the parameters and the body geometry. After this learning...
Relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. For a relevance feedback algorithm to be effective, it must grasp a user's query concept accurately...
