Crime scene classification from skeletal trajectory analysis in surveillance settings

no code implementations4 Jul 2022 Alina-Daniela Matei, Estefania Talavera, Maya Aghaei

Next, given the availability of the trajectory-level ground truth, we introduce a trajectory-based crime classification framework.

InstaIndoor and Multi-modal Deep Learning for Indoor Scene Recognition

1 code implementation23 Dec 2021 Andreea Glavan, Estefania Talavera

Furthermore, we highlight the potential of our approach by benchmarking on a YouTube-8M subset of indoor scenes as well, where it achieves 74% accuracy and 0. 74 F1-Score.

Playing to distraction: towards a robust training of CNN classifiers through visual explanation techniques

1 code implementation28 Dec 2020 David Morales, Estefania Talavera, Beatriz Remeseiro

Unlike the attention mechanisms that focus on the relevant parts of images, we aim to improve the robustness of the model by making it pay attention to other regions as well.

Behavioural pattern discovery from collections of egocentric photo-streams

no code implementations21 Aug 2020 Martin Menchon, Estefania Talavera, Jose M Massa, Petia Radeva

Based on the similarity among the time-frames that describe the collected days for a user, we propose a new unsupervised greedy method to discover the behavioural pattern set based on a novel semantic clustering approach.

Unsupervised routine discovery in egocentric photo-streams

no code implementations10 May 2019 Estefania Talavera, Nicolai Petkov, Petia Radeva

The routine of a person is defined by the occurrence of activities throughout different days, and can directly affect the person's health.

Towards Emotion Retrieval in Egocentric PhotoStream

no code implementations10 May 2019 Estefania Talavera, Petia Radeva, Nicolai Petkov

The availability and use of egocentric data are rapidly increasing due to the growing use of wearable cameras.

Towards Egocentric Person Re-identification and Social Pattern Analysis

no code implementations10 May 2019 Estefania Talavera, Alexandre Cola, Nicolai Petkov, Petia Radeva

We propose a model that enables us to evaluate and visualize social traits obtained by analysing social interactions appearance within egocentric photostreams.

On the Role of Event Boundaries in Egocentric Activity Recognition from Photostreams

no code implementations2 Sep 2018 Alejandro Cartas, Estefania Talavera, Petia Radeva, Mariella Dimiccoli

Event boundaries play a crucial role as a pre-processing step for detection, localization, and recognition tasks of human activities in videos.

Serious Games Application for Memory Training Using Egocentric Images

no code implementations27 Jul 2017 Gabriel Oliveira-Barra, Marc Bolaños, Estefania Talavera, Adrián Dueñas, Olga Gelonch, Maite Garolera

Mild cognitive impairment is the early stage of several neurodegenerative diseases, such as Alzheimer's.

R-Clustering for Egocentric Video Segmentation

no code implementations10 Apr 2017 Estefania Talavera, Mariella Dimiccoli, Marc Bolaños, Maedeh Aghaei, Petia Radeva

In this paper, we present a new method for egocentric video temporal segmentation based on integrating a statistical mean change detector and agglomerative clustering(AC) within an energy-minimization framework.

SR-Clustering: Semantic Regularized Clustering for Egocentric Photo Streams Segmentation

1 code implementation22 Dec 2015 Mariella Dimiccoli, Marc Bolaños, Estefania Talavera, Maedeh Aghaei, Stavri G. Nikolov, Petia Radeva

While wearable cameras are becoming increasingly popular, locating relevant information in large unstructured collections of egocentric images is still a tedious and time consuming processes.
