DIGITAL TWIN CREATION FOR SLUMS IN BRAZIL BASED ON UAV DATA

نویسندگان

چکیده

Abstract. Favelas are the most common type of informal settlements found in Brazil. The Housing Secretariat, City Hall, Sao Paulo, has conducted surveys using Unmanned Aerial Vehicles (UAVs) for favelas to facilitate slum upgrading projects and taken initiative create a digital twin areas. This study illustrates feasibility developing methodological workflow by automatic 3D building reconstruction slums from UAV point cloud 2D footprints with continuous link updating semantic information. focuses on facilitating data integration information into model provide additional about individual buildings slums. assessments concluded that proposed is suitable creating twins based cadastral data. However, had few limitations, which discussed this paper.

Steganography Scheme Based on Reed-Muller Code with Improving Payload and Ability to Retrieval of Destroyed Data for Digital Images

In this paper, a new steganography scheme with high embedding payload and good visual quality is presented. Before embedding process, secret information is encoded as block using Reed-Muller error correction code. After data encoding and embedding into the low-order bits of host image, modulus function is used to increase visual quality of stego image. Since the proposed method is able to embed...
