  Student researcher

  Conducted a variety of the self-motivated urban & spatial research in the Bartlett Centre for Spatial Advanced AnalysisDeep Learning based Human Body Size Measurement Application (Mar 2022 - Sep 2022)Conducted a pro-retail computer vision based deep learning research to develop the anthropometry (body measurement) application with a higher accuracy. Using TensorFlow and OpenCV in Python, the app based on BodyPix and COCO(Common Objects in Context) achieved 95.84% of accuracy in the experimentation of capturing the 4 body dimensions (arm length, leg length, chest girth and hip girth) for 10 volunteer subjects, which outperformed some of the previous DL research presenting 95.59% (Foysal et al., 2021) and 95.72% (Xiaohui et al., 2018). Flood AR - Am I at Risk? (Jan 2022 - May 2022)Built up an augmented reality web application that guides which flood risk zone of London the user is located in. Acquiring GPS location information from the user's smartphone, the app allows the user to interactively check the flood zone, flood alert and flood history of the locations. Aside from the AR application, I co-led the team, Delugeo, and created the webpage to raise the public's awareness the global and local flood vulnerability by visualising the related data. The project was acclaimed as one of the best projects in the programme and introduced as a sample work in the centre's promotion video. ▲ Project Website: https://nfabsikova.github.io/delugeo/▲ Web app: https://s-n-b-n.github.io/a/a.htmlLocation-Based AR Property Price Marker Application (Jan 2022 - Mar 2022)The application displays 2,366 price records of London Borough of Camden and Hackney sampled from 435,272 records in UK Land Registry's Price Paid Data. Using AR, the user can check the paid price for residential transactions via smartphone camera in real time. For geocoding, pgeocode package of Python was used. ▲ Price marker app: https://s-n-b-n.github.io/CASA0003/price.html Show less
