Koutou (THE LARYNX JAPAN) 32, 165 (2020); https://doi.org/10.5426/larynx.32.165.The present study clarified the swallowing-related neural activities using human intracranial electrodes. Eight epileptic participants fitted with intracranial electrodes on the orofacial cortex were asked to swallow a water bolus, and cortical oscillatory changes were investigated. High γ (75-150 Hz) power increases associated with swallowing were observed in the subcentral area. To decode swallowing intention, ECoG signals were converted into images whose vertical axes were the electrode’s contacts and whose horizontal axis was the time in milliseconds; these findings were used as training data. Deep transfer learning was carried out using AlexNet, and the power in the high-γ band was used to create the training image set. The accuracy reached 74%, and the sensitivity reached 83%. We showed that a version of AlexNet pre-trained with visually meaningful images can be used for transfer learning of visually meaningless images made up of ECoG signals. This study demonstrated that swallowing-related high γ activities were observed in the subcentral area, and deep transfer learning using high γ activities enabled us to decode the swallowing-related neural activities
Interactive virtual camera rendering from multiple sparse cameras using homographies and planar scene decompositions
No full textAs técnicas de renderização baseadas em imagens permitem que novas visualizações de uma cena sejam geradas a partir de um conjunto de imagens, obtidas a partir de pontos de vista distintos. Pela extensão dessas técnicas para o tratamento de vídeos, podemos permitir a navegação no tempo e no espaço de uma cena obtida a partir de múltiplas câmeras. Nesse trabalho, abordamos o problema de gerar novas visualizações fotorealistas de cenas dinâmicas, com objetos móveis independentes, a partir de vídeos obtidos de múltiplas câmeras com pontos de vista distintos. Os desafios para a solução do problema envolvem a fusão das imagens das múltiplas câmeras minimizando as diferenças de brilho e cor entre elas, a detecção e extração dos objetos móveis da cena e a renderização de novas visualizações combinando um modelo estático da cena com os modelos aproximados dos objetos móveis. Além disso, é importante que novas visualizações possam ser geradas em taxas de quadro interativas de maneira a permitir que um usuário navegue com naturalidade pela cena renderizada. As aplicações dessas técnicas são diversas e incluem aplicações na área de entretenimento, como nas televisões digitais interativas que permitem que o usuário escolha o ponto de vista de filmes ou eventos esportivos, e em simulações para treinamento usando realidade virtual, onde é importante que se haja cenas realistas e reconstruídas a partir de cenas reais. Apresentamos um algoritmo para a calibração das cores capaz de minimizar a diferença de cor e brilho entre as imagens obtidas a partir de câmeras que não tiveram as cores calibradas. Além disso, descrevemos um método para a renderização interativa de novas visualizações de cenas dinâmicas capaz de gerar visualizações com qualidade semelhante à dos vídeos da cena.Image-based rendering techniques allow the synthesis of novel scene views from a set of images of the scene, acquired from different viewpoints. By extending these techniques to make use of videos, we can allow the navigation in time and space of a scene acquired by multiple cameras. In this work, we tackle the problem of generating novel photorealistic views of dynamic scenes, containing independent moving objects, from videos acquired by multiple cameras with different viewpoints. The challenges presented by the problem include the fusion of images from multiple cameras while minimizing the brightness and color differences between them, the detection and extraction of the moving objects and the rendering of novel views combining a static scene model with approximate models for the moving objects. It is also important to be able to generate novel views in interactive frame rates allowing a user to navigate and interact with the rendered scene. The applications of these techniques are diverse and include applications in the entertainment field, with interactive digital televisions that allow the user to choose the viewpoint while watching movies or sports events, and in virtual-reality training simulations, where it is important to have realistic scenes reconstructed from real scenes. We present a color calibration algorithm for minimizing the color and brightness differences between images acquired from cameras that didn\'t have their colors calibrated. We also describe a method for interactive novel view rendering of dynamic scenes that provides novel views with similar quality to the scene videos

Software For Choral Conducting
No full textMOREIRA, C. C. Software Para Prática De Regência Coral. 2013. 60 f. Dissertação (Mestrado) - Instituto de Matemática e Estatística, Universidade de São Paulo, São Paulo, 2013. Neste documento um software é proposto para apoiar o ensino da regência coral com base em um modelo de aula padrão observado na disciplina: Análise Musical para Performance: Interfaces entre Criação e Interpretação a Partir do Universo Coral do Departamento de Música da Escola de Comunicações e Artes da Universidade de São Paulo. Neste software é possível: (i) monitorar, (ii) mensurar e (iii) avaliar os padrões de regência (gestos) de regência realizados e as posições corporais de um estudante de regência coral. O principal objetivo é permitir, através da interação com o software, que o estudante possa aprimorar sua consciência corporal através do monitoramento de seu posicionamento espacial enquanto realiza os padrões de regência e se vê projetado tridimensionalmente no sistema. Para que este monitoramento seja suportado, três módulos foram criados, de modo que as devidas configurações possam ser realizadas, assim como a visualização seja feita, a saber: (a) módulo de configuração de padrões de regência, onde padrões de regência são criados ou modificados; (b) módulo de criação de práticas, que podem ser: (b.1) sintéticas, e neste caso utilizam os padrões de regência pré-definidos em (a), dispondo-os em sequências ao longo do tempo as quais são associadas às mãos do regente, ou (b.2) gravadas, onde através do registro de movimentos corporais por um período de tempo em frente ao sensor, as juntas corporais são capturadas ao longo do tempo, de modo que se possa comparar estes movimentos com os realizados em tempo real; e (c), o módulo de visualização, onde o usuário poderá (c.1) assistir a reprise de práticas já realizadas, ou configuradas anteriormente; (c.2) comparar e visualizar práticas diversas entre si; ou ainda, (c.3) praticá-las de fato, onde receberá uma nota ao final do exercício. A idéia é que estudantes possam realizar práticas repetidas vezes, onde irão melhorando suas notas, e aprimorando seus gestos através da conscientização corporal. Outro ponto importante é que estudantes e regentes podem interagir entre si através da troca das configurações, já que estas são salvas em arquivos, possibilitando a criação de um repositório de regência coral, o que permite que as informações extrapolem os limites de sala de aula. Para implementar tal solução, algoritmos de visão computacional foram aplicados no contexto da regência coral, em conjunto com o sensor Kinect para auxiliar na captura das informações corporais. Por fim, busca-se iniciar um trabalho com o sentido de aprimorar a formação de regentes e possibilitar que o ensino desta arte seja fundamentado em dados quantitativos que poderão auxiliar o regente a tirar conclusões sobre os métodos e escolas de regência atualmente existentes.In this document a software to support the teaching of choral conducting is proposed based on the conducting classes observed while coursing the discipline: Musical Analysis for Performance on the Choral Universe in the Music Department of the School of Arts and Communications of University of Sao Paulo. Through this software is possible to: (i) monitor, (ii) measure and (iii) evaluate the choral conducting patterns (gestures) performed and the body positions of the student. The main objective is to allow, by interacting with the software, that the student improves his body self-perception by having his body position monitored while he performs the conducting patterns and sees himself tridimensionally projected in the system. To have this monitoring in place, three modules were created such that the needed configurations could be done as well as the visualization could have been done, they are: (a) conducting patterns configuration module, where the conducting patterns are created or modified; (b) practice creation module, the practices can be (b.1) synthetical, in this case they use the conducting patterns defined in (a), placing them in sequences accross the time which are associated to the hands of the conductor, or (b.2) recorded, in which case the body movements are recorded for a period of time in front of the sensor, the positions are stored along time and allow to compare these movements recorded with the user information in real-time; and (c), the visualization module, where the user can (c.1) watch a replay of the practices already performed, or configured previously; (c.2) compare and see diversified practices, or yet, (c.3) effectivelly practice them, in which case an evaluation mark will be given at the end. The idea is that students can do and repeat practices over, improving their marks and gestures through self-perception. Another important point is that students and conductors can interact by exchanging configurations, since all of them are saved in files, which allows creating a choral conducting repository which would extrapolate the classroom boundaries. To implement such solution computer vision algorithms were applied in the context of choral conducting, together with the Kinect sensor to help capturing the body information. At last, this work tries does the kick off for teaching conductors through the usage of technology, allowing that this art is teached based on quantitative data which can help the conductor drawing conclusions over the current conducting schools and methods
