PolyWorld: Polygonal Building Extraction with Graph Neural Networks in Satellite Images

1 code implementation CVPR 2022 Stefano Zorzi, Shabab Bazrafkan, Stefan Habenschuss, Friedrich Fraundorfer

While most state-of-the-art instance segmentation methods produce binary segmentation masks, geographic and cartographic applications typically require precise vector polygons of extracted objects instead of rasterized output.

Versatile Auxiliary Classifier with Generative Adversarial Network (VAC+GAN), Multi Class Scenarios

no code implementations19 Jun 2018 Shabab Bazrafkan, Peter Corcoran

Conditional generators learn the data distribution for each class in a multi-class scenario and generate samples for a specific class given the right input from the latent space.

Face Synthesis with Landmark Points from Generative Adversarial Networks and Inverse Latent Space Mapping

no code implementations1 Feb 2018 Shabab Bazrafkan, Hossein Javidnia, Peter Corcoran

There have been a tremendous amount of attempts to detect these points from facial images however, there has never been an attempt to synthesize a random face and generate its corresponding facial landmarks.

An End to End Deep Neural Network for Iris Segmentation in Unconstraint Scenarios

no code implementations7 Dec 2017 Shabab Bazrafkan, Shejin Thavalengal, Peter Corcoran

Finally, the proposed model is compared with SegNet-basic, and a near-optimal tuning of the network is compared to a selection of other state-of-art iris segmentation algorithms.

Smart Augmentation - Learning an Optimal Data Augmentation Strategy

no code implementations24 Mar 2017 Joseph Lemley, Shabab Bazrafkan, Peter Corcoran

Smart Augmentation works by creating a network that learns how to generate augmented data during the training process of a target network in a way that reduces that networks loss.
