“…Then, visual database is converted into digital data units (vector form) that is read by computing programs. A hybrid approach is need to perfect the character modelling (Kazmi, You, and Zhang, 2015). Since it is quite complicated and sophisticated work, a Digital Designer is required with a combined talent of artistic and digital skills.…”

The Modern Architecture Movement’s stance against ornamentation, however, the architectural characteristics of the International Style in Indonesia in 1960s are often combined with iconography in the building façade or structural wall. The existence of these artworks inside or outside of various buildings are considered to colour the triumph of Modern Architectural Style. This Design-Build project of SARINAH heritage mall building in Jakarta is organized in a multidisciplinary manner by accommodating an adaptive reuse method. Due to spatial changes on the ground floor, 15 figures of the relief-sculptures as a part of the structural wall, which had been ‘buried’ for 30 years, were rediscovered and they needed to be restored. This case study seeks to reveal the uniqueness of the ongoing transformation project, especially how to treat the heritage building to meet to the contemporaneous. By accommodated “urban forest” theme and restore the historical artwork, the reappearances of the SARINAH heritage mall can meet to the sustainable city goals, enriched by the 15 relief-sculptures reinforces the cultural aesthetics for the shopping centre’s urban destination. Meanwhile, to avoid the high risk to casting the historical artwork then the digitally record held by digital sculpting.

“…In addition to the aforementioned solutions, depth maps obtained from 3D reconstruction have been used successfully in many different fields of study such as industry, medicine, surface inspection, biometry, and 3D modeling (e.g., Gallen et al, 2015;Han and Zhu, 2005;Kazmi et al, 2016).…”

The shape-from-shading (SFS) technique uses the pattern of shading in images in order to obtain 3D view information. By virtue of their ease of implementation, linearization-based SFS algorithms are frequently used in the literature. In this study, Fourier coefficients of central differences obtained from gray-level images are employed, and two basic linearization-based algorithms are combined. By using the functionally generated surfaces and 3D reconstruction datasets, the hybrid algorithm is compared with linearization-based approaches. Five different evaluation metrics are applied on recovered depth maps and the corresponding gray-level images. The results on defective sample surfaces are also included to show the effect of the algorithm on surface reconstruction. The proposed method can prevent erroneous estimates on object boundaries and produce satisfactory 3D reconstruction results in a low number of iterations.

“…3 D human characters, in particular, 3D faces, are essential elements in virtual and augmented realities [1], [2]. Blendshape, a linear facial expression model, has been widely used in various applications to generate realistic 3D human faces such as face recognition [3], [4], face tracking [5]- [7], performance-based facial capture [8], [9], human reconstruction [10]- [13], and facial retargeting [14], [15] thanks to its simplicity and expressiveness.…”

A Selective Expression Manipulation With Parametric 3D Facial Model

et al. 2023

This paper proposes a novel method to represent expressive 3D facial shapes called the Selective Expression Manipulation (SEM) by fitting the expression coefficients of delta-blendshapes, which is the standard parametric facial model widely used in industries. SEM focuses on preserving blendshape semantics to characterize the facial shapes since the facial shape obtained by minimizing the distance to sparse facial landmarks might fail to signify a facial expression from a human being's perspective. Assuming each delta-blendshape corresponds to a facial movement with semantic meaning, SEM finds a series of facial motions required to compose the target facial expression. In addition, SEM sequentially determines a sufficient number of expressions and coefficients closely resembling the target facial movements by introducing similarities to quantify the directional correlation of facial motions between a target and a blendshape, excluding redundant expressions in terms of motions from the neutral shape. As a result, far fewer inter-correlated expressions that significantly increase the target correlation can be obtained. Furthermore, SEM exhibits substantial improvement in accuracy, correlation, semantics, and stability in experiments over previous facial fitting schemes and state-of-the-art methods. It is demonstrated that SEM enables accurate and realistic 3D facial shape generation by semantically manipulating expression deltablendshapes.
