In this paper we present an augmented reality system for automatic try-on of 3D virtual eyeglasses. The user can select from various virtual models of eyeglasses for trying-on and the system will automatically fit the selected virtual glasses on the user's face. The user can see his/her face as in a mirror with the 3D virtual glasses fitted on it. We also(More)
The human visual system (HVS) uses several methods to interactively adapt to the incredible real-world range of light intensities, continually changing to effectively perceive visual information. Eye HDR is a new approach to the problem of displaying high-dynamic-range (HDR) content on low-dynamic-range displays. Instead of creating a single static image,(More)
—Ripple designs of FIR digital differentiators are suitable for wideband applications, but cannot produce very high accuracies in narrow bands. In this paper, we present new simple designs for FIR digital differentiators, with very high accuracies in the narrow bands centered at arbitrary frequencies in the lower half of the frequency band. First, a new(More)
—Maximally linear digital differentiators (DDs) are known for high accuracy in narrow frequency bands centered at the frequency for which they are designed. In this paper, designs of DDs of odd and even lengths having maximal linearity at the middle of the frequency band are presented. Applying the maximal linearity constraints to the magnitude response of(More)
—MAXIMALLY FLAT (MAXFLAT) finite-impulse response digital filters, including the Hilbert transformers (HTs), have the smoothest magnitude responses among the available types of FIR digital filters. However, the transition bands of MAXFLAT filters are relatively wider, and this makes them unattractive in certain applications. We present new designs of even(More)
Complete 3D surface models of real objects can be obtained by integrating several range images, each representing a different view of the object. The mesh generated for these models have irregular connectivity in general. Several remeshing techniques have been proposed to approximate the irregular mesh models with regular meshes, which have several(More)
Virtual try-on of clothes has received much attention recently due to its great commercial potential [Hauswiesner et al. 2011 and Meng et al. 2010]. In these applications, a user standing in front of a display mounted with RGBD camera can see him/her in virtual clothes without taking off actual clothes and wearing new ones. The major challenges faced in(More)
