Most existing 3D virtual try-on systems put clothes designed in one environment on a human captured in another environment, which cause the mismatching color and brightness problem. And also typical 3D clothes modeling starts with manually designed 2D patterns, deforms them to fit on a human, and applies stitching to sew those patterns together. Such work usually relies on labor work. In this thesis, we describe an approach to reconstruct clothes and human that both are from the same space. With multiple Kinects, it models the 3D clothes directly out of a dressed mannequin without the need of the predefined 2D clothes patterns, and fits them to a human user. Our approach has several advantages: (i) a simple hardware setting consisted of multiple Kinects to capture a human model; (ii) 3D clothes modeling directly out of captured human figure. To the best of our knowledge, our work is the first one which separates clothes out of captured human figure; (iii) resizing of clothes adapting to any sized human user; (iv) a novel idea of virtual try-on where clothes and human are captured in the same location.

Geometric reconstruction of dynamic objects is a fundamental task of computer vision and graphics, and modeling human body of high fidelity is considered to be a core of this problem. Traditional human shape and motion capture techniques require an array of surrounding cameras or subjects wear reflective markers, resulting in a limitation of working space and portability. In this dissertation, a complete process is designed from geometric modeling detailed 3D human full body and capturing shape dynamics over time using a flexible setup to guiding clothes/person re-targeting with such data-driven models. As the mechanical movement of human body can be considered as an articulate motion, which is easy to guide the skin animation but has difficulties in the reverse process to find parameters from images without manual intervention, we present a novel parametric model, GMM-BlendSCAPE, jointly taking both linear skinning model and the prior art of BlendSCAPE (Blend Shape Completion and Animation for PEople) into consideration and develop a Gaussian Mixture Model (GMM) to infer both body shape and pose from incomplete observations. We show the increased accuracy of joints and skin surface estimation using our model compared to the skeleton based motion tracking. To model the detailed body, we start with capturing high-quality partial 3D scans by using a single-view commercial depth camera. Based on GMM-BlendSCAPE, we can then reconstruct multiple complete static models of large pose difference via our novel non-rigid registration algorithm. With vertex correspondences established, these models can be further converted into a personalized drivable template and used for robust pose tracking in a similar GMM framework. Moreover, we design a general purpose real-time non-rigid deformation algorithm to accelerate this registration. Last but not least, we demonstrate a novel virtual clothes try-on application based on our personalized model utilizing both image and depth cues to synthesize and re-target clothes for single-view videos of different people.

This bachelor thesis explores a virtual try-on interface in the context of the fashion product category. It is argued that virtual representations of product offerings can stimulate consumers’ purchase intentions, and thus, enact an online transaction. The purpose is to investigate how market-based AR/VR influences the behavior of consumers along the customer journey. A qualitative research approach was undertaken to answer the exploratory question. The context of the empirical bachelor thesis is the virtual try-on Synsam Style Lab where two qualitative research methods were conducted. These methods consisted of a document study on Synsam Style Lab and three synchronous online focus group interviews that laid the foundation of the thematic analysis. The purpose of conducting these qualitative research methods was to shed light on whether or not Synsam Style Lab could facilitate consumers’ online buying decision process. Consumers who saw convenience in Synsam Style Lab often expressed reasons related to the theme Alleviate. On the contrary, if consumers interaction with Synsam’s virtual try-on yielded negative experience, then their reasons were often in connection with the theme Insufficiency.  The context of this bachelor thesis is restricted to the fashion eyewear segment and does not represent the total fashion industry. Only members of Generation Y, also known as millennials, participated in the synchronous online focus group interviews. Therefore, incorporating the perspectives of other demographics could contribute to a diversified discovery of findings. Previous research has not explicitly investigated the influence of AR/VR applications on consumers’ engagement in a fashion retail setting. Hence, this bachelor thesis provides new dimensions within the field of market-based AR/VR applications.

Denna studie skrivs i ett intresse av ett företag som arbetar med 3D-simulering vid prototypframtagning av provplagg. Syfte med studien är att undersöka korrespondensen mellan virtuell- och fysisk avprovning gällande storlek, passform och val av tyg. I studien undersöks 3D-simuleringsprogrammet CLO 3D och digitalisering av tygprov med applikationen CLO Fabric kit, som komplement i syfte att utvärdera skillnaden mellan virtuell- och fysisk avprovning. Två plagg, bestående av t-tröja i bomullstrikå och skjorta i linneväv, provas av i storlekar: XS, M och XL på tre provpersoner och tre avatarer med motsvarande mått. Ett protokollmed foton från båda avprovningarna bedöms med frågor gällande plaggets visuella skillnad och passform. Resultatet visade att T-tröjan i bomullstrikå gav likvärdigt passform mellan virtuell- och fysisk avprovning i samtliga storlekar. Vid avprovning av skjortan i linneväv var passformsskillnaden mellan virtuell- och fysisk avprovning på storlek XL tydlig. Övriga storlekar hade däremot ett likartat resultat.3D-simulering är en effektiv avprovningsmetod, då man kan modifiera avaterns mått, digitalisera in tygprover och prova av flera storlekar vid virtuell avprovning. Däremot behöver man vara medveten att flera faktorer kan påverka passformen vid virtuell avprovning som till exempel avatarens kroppshållning och tygets mekaniska egenskaper vid digitalisering. / This study writes in an interest of a company that works with 3D-simulation in prototyping sample garments. The purpose of the study is to investigate the correspondence between the virtual and physical try-on regarding size, fit and fabric choice. The study examines the 3D-simulation program CLO 3D and digitization of fabric samples with the CLO Fabric kit application as a complement to evaluate the difference between virtual and physical try-on. Two garment, consisting of t-shirt made of knitted cotton and a shirt made of linen, are fitted in size XS, M and XL on three test persons and three avatars with corresponding measurements. A protocol containing photos from both virtual and physical try-on where evaluated with questions regarding the balance and fit of the garment. It showed that the T-shirt made of knitted cotton gave equivalent results between virtual and physical try-on in all sizes. When comparing the shirt in linen, the fit differed in size XL during virtual and physical try-on. However, Size XS and M had a similar result during virtual and physical try-on. Using 3D-simulation is an advantage when you can modify the avatar's dimensions, digitize fabric samples and try multiple sizes during virtual try-on. However, one needs to be aware that several factors can affect the fit during virtual try-on, such as the avatar posture and the mechanical properties of the fabric during digitization.

In-flight entertainment (IFE) is facing exciting times ahead as more and more technological advancements find its way into the IFE-systems. With the increasing hardware capabilities of IFE-systems, one exciting technology which could be seen infuture IFE-systems is augmented reality (AR). AR could allow for virtual try-on (VTO) in a webshop, where passengers can view virtual representations of for instance, glasses or headpieces, augmented onto themselves through a camera on the IFE-screen. However, integrating VTO in a webshop comes with new challenges, both for the designer and the developer. This thesis has examined design guidelines for AR in a literature study, along with general principles for user experience (UX). Based on the findings from the literature study, a prototype for a webshop with integrated VTO, targeting IFE, has been build in an iterative design process. Furthermore, a small application has been built using Google’s AR-framework ARCore for Android, where users can try different virtual glasses. The literature study, along with usability testing in each design iteration, showed that there are no guidelines which can cover everything when designing for AR; however, the design guidelines presented by Google and Apple are a great place to start. Furthermore, the usability testing showed that people have certain expectations of a webshop, which indicates that VTO should be integrated seamlessly into the application without interfering with the layout. The application development showed that ARCore certainly is a potent tool when it comes to AR-development. However, ARCore is not open source,which could make it less appealing for companies in need of highly flexible solutions.
