A simple, strong baseline for building damage detection on the xBD dataset

1 code implementation30 Jan 2024 Sebastian Gerard, Paul Borne-Pons, Josephine Sullivan

We construct a strong baseline method for building damage detection by starting with the highly-engineered winning solution of the xView2 competition, and gradually stripping away components.

Probabilistic 3d regression with projected huber distribution

1 code implementation9 Mar 2023 David Mohlin, Josephine Sullivan

We also show that the mode of the predicted distribution outperform our regression baselines.

Contrastive pretraining for semantic segmentation is robust to noisy positive pairs

no code implementations24 Nov 2022 Sebastian Gerard, Josephine Sullivan

Domain-specific variants of contrastive learning can construct positive pairs from two distinct in-domain images, while traditional methods just augment the same image twice.

Persistent Evidence of Local Image Properties in Generic ConvNets

no code implementations24 Nov 2014 Ali Sharif Razavian, Hossein Azizpour, Atsuto Maki, Josephine Sullivan, Carl Henrik Ek, Stefan Carlsson

Supervised training of a convolutional network for object classification should make explicit any information related to the class of objects and disregard any auxiliary information associated with the capture of the image or the variation within the object class.

Factors of Transferability for a Generic ConvNet Representation

no code implementations22 Jun 2014 Hossein Azizpour, Ali Sharif Razavian, Josephine Sullivan, Atsuto Maki, Stefan Carlsson

In the common scenario, a ConvNet is trained on a large labeled dataset (source) and the feed-forward units activation of the trained network, at a certain layer of the network, is used as a generic representation of an input image for a task with relatively smaller training set (target).

CNN Features off-the-shelf: an Astounding Baseline for Recognition

4 code implementations23 Mar 2014 Ali Sharif Razavian, Hossein Azizpour, Josephine Sullivan, Stefan Carlsson

We report on a series of experiments conducted for different recognition tasks using the publicly available code and model of the \overfeat network which was trained to perform object classification on ILSVRC13.
