Sketchformer: Transformer-based Representation for Sketched Structure
Leo Sampaio Ferraz Ribeiro, Tu Bui, John Collomosse +1
Sketchformer is a novel transformer-based representation for encoding free-hand sketches input in a vector form, i.e. as a sequence of strokes. Sketchformer effectively addresses m…
Generalization of feature embeddings transferred from different video anomaly detection domains
Fernando Pereira dos Santos, Leonardo Sampaio Ferraz Ribeiro, Moacir Antonelli Ponti
Detecting anomalous activity in video surveillance often involves using only normal activity data in order to learn an accurate detector. Due to lack of annotated data for some spe…
Are pre-trained CNNs good feature extractors for anomaly detection in surveillance videos?
Tiago S. Nazare, Rodrigo F. de Mello, Moacir A. Ponti
Recently, several techniques have been explored to detect unusual behaviour in surveillance videos. Nevertheless, few studies leverage features from pre-trained CNNs and none of th…
Unsupervised representation learning using convolutional and stacked auto-encoders: a domain and cross-domain feature space analysis
Gabriel B. Cavallari, Leonardo Sampaio Ferraz Ribeiro, Moacir Antonelli Ponti
A feature learning task involves training models that are capable of inferring good representations (transformations of the original space) from input data alone. When working with…
