Streetscapes are an important part of the urban landscape, analysing and studying them can increase the understanding of the cities infrastructure, which can lead to better planning and design of the urban living environment. In this paper, we used Google API to obtain street view images of Osaka City. The semantic segmentation model PSPNet is used to segment the Osaka City street view images and analyse the Green View Index (GVI) data of Osaka area. Based on the GVI data, three methods, namely corridor analysis, geometric network and a combination of them, were then used to calculate the optimal GVI paths in Osaka City. The corridor analysis and geometric network methods allow for a more detailed delineation of the optimal GVI path from general areas to specific routes. Our analysis not only allows for the calculation of specific routes for the optimal GVI paths, but also allows for the visualisation and integration of neighbourhood landscape data. By summarising all the data, a more specific and objective analysis of the landscape in the study area can be carried out and based on this, the available natural resources can be maximised for a better life.
The current paradigm in privacy protection in street-view images is to detect and blur sensitive information. In this paper, we propose a framework that is an alternative to blurring, which automatically removes and inpaints moving objects (e.g. pede
The aim of this article is to present an overview of the major families of state-of-the-art index and materialized view selection methods, and to discuss the issues and future trends in data warehouse performance optimization. We particularly focus o
In this paper, we propose a novel Joint framework for Deep Multi-view Clustering (DMJC), where multiple deep embedded features, multi-view fusion mechanism and clustering assignments can be learned simultaneously. Our key idea is that the joint learn
Materialized views and indexes are physical structures for accelerating data access that are casually used in data warehouses. However, these data structures generate some maintenance overhead. They also share the same storage space. Most existing st
Studies evaluating bikeability usually compute spatial indicators shaping cycling conditions and conflate them in a quantitative index. Much research involves site visits or conventional geospatial approaches, and few studies have leveraged street vi
