BEGL: boundary enhancement with Gaussian Loss for rock-art image segmentation

et al. 2023

Rock-art has been scratched, carved, and pecked into rock panels all over the world resulting in a huge number of engraved figures on natural rock surfaces that record ancient human life and culture. To preserve and recognize these valuable artifacts of human history, 2D digitization of rock surfaces has become a suitable approach due to the development of powerful 2D image processing techniques in recent years. In this article, we present a novel systematical framework for the segmentation of different petroglyph figures from 2D high-resolution images. The novel boundary enhancement with Gaussian loss (BEGL) function is proposed aiming at refining and smoothing the rock-arts boundaries in the basic UNet architecture. Several experiments on the 3D-pitoti dataset demonstrate that our proposed approach can achieve more accurate boundaries and superior results compared with other loss functions. The comprehensive framework of petroglyph segmentation from 2D high-resolution images provides the foundation for recognizing multiple petroglyph marks. The framework can then be extended to other cultural heritage digital protection domain easily.

“…These digital models can be experiences via dedicated internet sites, as well as through 3D films shown in different types of places, requiring virtual reality glasses or headsets (on the subject of the Santimamiñe Cave in Spain, see Baeza and Cantalejo 2013;Kaminski 2014). Coupling a sensory experience with digital reality, hybrid devices can also enrich in-situ visits via the use of augmented reality, these new interpretation techniques leading the public in turn to new manners of appropriating cultural heritage sites (López-Menchero Bendicho et al 2017;Mazel 2017). b.…”

The Janus-faced Dilemma of Rock Art Heritage Management in Europe: A Double Dialectic Process between Conservation and Public Outreach, Transmission and Exclusion

Conservation and Management of Archaeological Sites

In this paper, we discuss the management strategies applied to rock art in western cultural contexts. How do the persons responsible for rock art sites manage the tension between the two opposing imperatives of, on one side, their conservation and long-term transmission, and the other, their opening to the public to enable their heritage value to be shared and transmitted in the present? What forms do the articulation of conservation and public access take? Drawing on a typology of the many possible configurations, we discuss the choices made by the actors in charge of decorated sites, as well as the variability of some of the criteria considered, such as the 'carrying capacity' of a site, to define visit protocols. We thus demonstrate that the implementation of quotas depends not only on climatic and biochemical factors but on the priorities of the decision-makers and their interpretation of the preservation of a decorated site as well. Finally, our empirical approach leads to a discussion of the accessibility of rock art sites from the angle of heritage access rights and the heritage-making process. What meaning do we ascribe to sites that remain closed and thus cannot be experienced by the public? To what degree are they (still?) heritage sites and for whom? Through an empirical and comparative approach, we address these questions based on an analysis of case studies in France and northern Spain.

“…Rock art is thought of as a fragile natural heritage object. It deteriorates over time to the factors above, so documenting the motifs in digital form is vital for future research, reference, and dissemination (Bendicho et al, 2017). Documenting rock art in a digital three-dimensional (3D) model has become demanding in cultural heritage.…”

Abstract. This paper presents a developed methodology of 3D modelling of rock art painting located at high above shelter floor based on close-range photogrammetric technique. Instead of using elevated devices to reach inaccessible paintings due to high elevation, the developed method proposed a simple technique. The camera was mounted on an expandable pole to acquire the panel with normal and tilted camera settings. Due to inaccessibility to place the control point marker on the panel surface, the distribution of photo control was positioned below the panel. Based on the configuration, the image of the panel was acquired using the low-spatial resolution multispectral camera in a two elevated strips position that imitates the aerial photogrammetry flight line. The camera was set parallely to the painting panel on both strips, with additional tilted geometry included at the upper strip of the camera block. The acquired multispectral images were then processed using commercial SfM photogrammetry software to generate a 3D point cloud. The accuracy of constructed point cloud was then analysed by comparing it with the point cloud generated using a terrestrial laser scanner (TLS). The result has shown that the multispectral 3D point cloud has a small deviation against the TLS point cloud. The mean deviation was -0.43mm, indicating a slight downscaled on the multispectral point cloud.
