Temporal city modeling using street level imagery

Computer Vision and Image Understanding, 2017
We propose two methods for detecting city changes depending on available data.Presence of buildings is estimated by comparing street images and a 2D city map.Scene changes are estimated from an image pair roughly aligned with GPS data.The proper use of these images enables temporal city modeling in various situations. Estimation of the temporal changes

Text recognition on traffic panels from street-level imagery

2012 IEEE Intelligent Vehicles Symposium, 2012
Text detection and recognition in images taken in uncontrolled environments still remains a challenge in computer vision. This paper presents a method to extract the text depicted in road panels in street view images as an application to Intelligent Transportation Systems (ITS).

The value of crowdsourced street-level imagery: examining the shifting property regimes of OpenStreetCam and Mapillary

open access: yesGeo Journal, 2018
OpenStreetCam and Mapillary are two increasingly popular online services centered on providing street-level imagery through close association with the OpenStreetMap platform and crowdmapping community. While both services provide crowdsourced street-level imagery, the differences in their aims and operations present an opportunity to discuss the ...

Every single street? Rethinking full coverage across street‐level imagery platforms

Transactions in GIS, 2019
AbstractStreet‐level images taken by vehicles and pedestrians have found a role in various companies’ location‐based intelligence services. Some platforms collect their images using their own cars and drivers, while others rely on crowdsourcing; however, to what extent can we expect crowdsourced approaches to reach the imagery coverage levels obtained ...

Microclimate Vision: Multimodal prediction of climatic parameters using street-level and satellite imagery

open access: yesSustainable Cities and Society
High-resolution microclimate data is essential for capturing spatio-temporal heterogeneity of urban climate and heat health management. However, previous studies have relied on dense measurements that require significant costs for equipment, or on physical simulations demanding intensive computational loads. As a potential alternative to these methods,

Mapping urban trees with deep learning and street-level imagery

2020
Planning and managing urban trees and forests for livable cities remains an outstanding challenge worldwide owing to scarce information on their spatial distribution, structure and composition. Sources of tree inventory remain limited due to a lack of detailed and consistent inventory assessments.
