Learning multiplane images from single views with self-supervision
Gustavo Sutter P. Carvalho, Diogo C. Luvizon, Antonio Joia Neto +2
Generating static novel views from an already captured image is a hard task in computer vision and graphics, in particular when the single input image has dynamic parts such as per…
Adaptive Multiplane Image Generation from a Single Internet Picture
Diogo C. Luvizon, Gustavo Sutter P. Carvalho, Andreza A. dos Santos +7
In the last few years, several works have tackled the problem of novel view synthesis from stereo images or even from a single picture. However, previous methods are computationall…
Human activity recognition from mobile inertial sensors using recurrence plots
Otávio A. B. Penatti, Milton F. S. Santos
Inertial sensors are present in most mobile devices nowadays and such devices are used by people during most of their daily activities. In this paper, we present an approach for hu…
Exploiting ConvNet Diversity for Flooding Identification
Keiller Nogueira, Samuel G. Fadel, Ícaro C. Dourado +7
Flooding is the world's most costly type of natural disaster in terms of both economic losses and human causalities. A first and essential procedure towards flood monitoring is bas…
Bag of Attributes for Video Event Retrieval
Leonardo A. Duarte, Otávio A. B. Penatti, Jurandy Almeida
In this paper, we present the Bag-of-Attributes (BoA) model for video representation aiming at video event retrieval. The BoA model is based on a semantic feature space for represe…
Towards Better Exploiting Convolutional Neural Networks for Remote Sensing Scene Classification
Keiller Nogueira, Otávio A. B. Penatti, Jefersson A. dos Santos
We present an analysis of three possible strategies for exploiting the power of existing convolutional neural networks (ConvNets) in different scenarios from the ones they were tra…
Semantic Diversity versus Visual Diversity in Visual Dictionaries
Otávio A. B. Penatti, Sandra Avila, Eduardo Valle +1
Visual dictionaries are a critical component for image classification/retrieval systems based on the bag-of-visual-words (BoVW) model. Dictionaries are usually learned without supe…
Bag of Genres for Video Retrieval
Leonardo A. Duarte, Otávio A. B. Penatti, Jurandy Almeida
Often, videos are composed of multiple concepts or even genres. For instance, news videos may contain sports, action, nature, etc. Therefore, encoding the distribution of such conc…
Are visual dictionaries generalizable?
Otavio A. B. Penatti, Eduardo Valle, Ricardo da S. Torres
Mid-level features based on visual dictionaries are today a cornerstone of systems for classification and retrieval of images. Those state-of-the-art representations depend crucial…
