Virtual try-on synthesizes garments for the target bodies in 2D/3D domains. Even though existing virtual try-on methods focus on redressing garments, the virtual try-on hair, shoes and wearable accessories are still under-reached. In this paper, we present the first general method for virtual try-ons that is fully automatic and suitable for many items including garments, hair, shoes, watches, necklaces, hats, and so on. Starting with the pre-defined wearable items on a reference human body model, an automatic method is proposed to deform the reference body mesh to fit a target body for obtaining dense triangle correspondences. Then, an improved fit metric is used to represent the interaction between wearable items and the body. For the next step, with the help of triangle correspondences and the fit metric, the wearable items can be fast and efficiently inferred by the shape and posture of the targeted body. Extensive experimental results show that, besides automation and efficiency, the proposed method can be easily extended to implement the dynamic try-on by applying rigging and importing motion capture data, being able to handle both tight and loose garments, and even multi-layer clothing.

During vertical or fore-and-aft vibrations of a seated human body, the motion of the head is influenced by backrest forces transmitted to the lumbar region of the spine. Thus, it is essential to consider backrest support while developing a human body model to capture direct and cross-axis seat to head transmissibility. For this purpose, twelve degrees of freedom seated human body model of the appropriate level of complexity with inclined backrest support has been developed in this work. The interconnection of masses is modelled using rotational and translational springs-dampers and the contact with an inclined backrest gives a better simulation of forces transmitted to the lower torso in the x-z direction. The model parameters were identified and optimized using a multi-objective genetic algorithm by minimizing the least square difference between experimental head motion and analytical results. Subsequently, a sensitivity study was carried out to find the effect of model parameters on the peak transmissibility modulus and resonant frequency. This will help in refining the design of the seat and backrest for improving comfort. Modal analysis was carried out for an improved understanding of the relative motion of different sections. Power absorbed at different locations of the human body was studied to identify regions susceptible to long term damage. Internal forces in the neck region were also determined and these can be used to characterize the neck pain due to prolonged exposure to such vibrations. The research work reported in this work offers an in-depth understanding of biodynamic responses of backrest supported human body subjected to vertical/horizontal vibrations. We expect it to offer vehicle designers some insights to control human body parameters (acceleration/forces /moments/power absorbed/modal displacements/lower back pain) and design appropriate restraints-supports for improved comfort.
