Motion Correspondence

This study addressed the ‘correspondence’ problem of apparent-motion (AM) perception in which parts of a scene must be matched with counterparts separated in time and space. Given evidence that AM correspondence can be mediated by two distinct processes—one based on a low-level motion-detection mechanism (the Reichardt process), the other involving the tracking of objects by visual attention (the attention-based process)—the present study explored how these processes interact in the perception of apparent motion between hierarchically structured figures. In three experiments, hierarchical figures were presented in a competition motion display so that, across frames, figures were identical at either the local or the global level. In experiment 1 it was shown that AM occurred between locally identical figures. Furthermore, with the Reichardt AM component eliminated in experiments 3 and 4, no preference was obtained for either level. While evidence from previous studies suggests that form extraction for hierarchically structured figures proceeds from the global to the local level, the present results indicate the irrelevance of such a global precedence in AM correspondence. In addition, it is suggested that Reichardt AM correspondence between local elements constrains attention-based AM correspondence between global figures so that both components move in the same direction. It is argued that this constraining process represents an elegant means of achieving AM correspondence between objects undergoing complex transformations.

Abstract Stereo vision is an important feature that enables machine vision systems to perceive their environment in 3D. While machine vision has spawned a variety of software algorithms to solve the stereo-correspondence problem, their implementation and integration in small, fast, and efficient hardware vision systems remains a difficult challenge. Recent advances made in neuromorphic engineering offer a possible solution to this problem, with the use of a new class of event-based vision sensors and neural processing devices inspired by the organizing principles of the brain. Here we propose a radically novel model that solves the stereo-correspondence problem with a spiking neural network that can be directly implemented with massively parallel, compact, low-latency and low-power neuromorphic engineering devices. We validate the model with experimental results, highlighting features that are in agreement with both computational neuroscience stereo vision theories and experimental findings. We demonstrate its features with a prototype neuromorphic hardware system and provide testable predictions on the role of spike-based representations and temporal dynamics in biological stereo vision processing systems.

The study was carried out with a sample of 30 teachers   and 30 speakers from the VIII, IX and X cycle of the Language Studies Program of   the Faculty of Education and Humanities of the National University of San Martín, Tarapoto. In this context, implementing scientific ally conceived university didactics is a fundamental element of professional   transformation of teachers and the improvement of the training practice they develop. One of the fundamental conditions for improving the quality of university teaching lies, in our view, in making possible a substantive change in the configuration of the professional identity of university teachers. In the light of these considerations, studies that provide theoretical modelling on investigative skills are insufficient since most theoretical and empirical results focus, specifically, on the training of a profession. The careers with the greatest presence in the subject are Medicine and Bachelor of Education. In the case of the latter, the most repeated object of study is initial investigative or postgraduate training. In the research, it was raised that the act of the situation between university didactics at the National University of San Martín–Tarapoto and the development of research skills inherent in students of the VIII, IX and X cycle of the Language Studies Program are significantly related. A correlational descriptive study was conducted; theoretical methods of induction, analysis, synthesis, as well as empirical measurement methods were used, as well as statistical methods and individual survey techniques. For statistical contrast of the hypothesis, Pearson's statistical correlation technique was used; hypothesis test, there is statistical evidence with a significance level of 5%. The conclusions shape the validity of the hypotheses.

The Relationship

This study aims to analyze and examine (1) the relationship of the principal situational leadership with teachers’ performance, (2) the relationship of principal supervision with teachers’ performance, and (3) the relationship of principal situational leadership and supervision all together with the performance of teachers at Madrasah Aliyah in West Papua. This study uses a survey with correlation technique. Research conducted in the province of West Papua, which consists of six districts or cities: Sorong, Manokwari, Fakfak, Raja Ampat, Kaimana, and Sorong. Samples are selected in proportion taking the proportion of the population of teachers in each district or city into account. Data are collected using a questionnaire and analyzed using statistical correlation (simple and double), calculating the coefficient of determination, and testing the significance of the partial correlation. The results show that (1) there is a positive correlation between the teachers’ performance and principal situational leadership; (2) there is a positive relationship between principal supervision and teachers’ performance; and (3) there is a significant relationship and influence of situational leadership and supervision of the principal on teachers’ performance at Madrasah Aliyah in West Papua. In other words, increasing the effectiveness of situational leadership and supervision of the principal would have a positive influence on improving the performance of teachers in the madrassas.
