Weakly supervised fully convolutional networks using OBIA classification output
2019 Joint Urban Remote Sensing Event (JURSE), 2019In this paper, we present a methodology for preparing reference data to be used in training a fully convolutional neural network. It is a laborious and timeconsuming task to prepare adequate training data for a Fully convolutional network (FCN) since the tiles need to be fully labeled.

Cropland Extraction Based on OBIA and Adaptive Scale Pre-estimation
Photogrammetric Engineering & Remote Sensing, 2016Object-based image analysis (OBIA) provides a solution for cropland extraction from high spatial resolution remote sensing images. Currently, scale parameter selection is often dependent on subjective trial-and-error methods or post-evaluation of multi-segmentation, which directly reduces efficiency of cropland extraction.

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Every day, ships of different type, size and origin cross the world seas. Not only for commerce and transport, but also for illegal activities. In addition to conventional positioning and tracking systems, detection with Earth observation satellites is an effective means to monitor human movements across the sea.

UAV Photogrammetry and OBIA Classification for Decay Mapping in Built Heritage
2025 IEEE International Workshop on Metrology for Living Environment (MetroLivEnv)One of the first steps in the development of BIM (Building Information Model) for existing structure is linked to the acquisition and mapping of decay information. Currently, the most widely used practice is visual inspection carried out by experts in the field an based on visual inspection, that requires significant effort in terms of time, human ...

The potential of OBIA for SAR-based flood mapping
2018In our changing world, floods are a threat of increasing importance causing major fatalities and economic losses. Within this perspective, flood extent mapping is of great importance for both damage assessment and improving flood forecasts. While flood mapping through optical imagery is often hampered by the presence of clouds, Synthetic Aperture Radar
