The attention function has been classified into (i) sustained attention, (ii) selective attention, (iii) controlled attention, (iv) distributed attention, and (v) capacity for attention. Ordinarily, in order to evaluate the function of attention, the digital cancellation test (D-CAT) or trail making test (TMT) are employed. However, these evaluations are in the form of paper tests, and cannot effectively...
In order to explore the mental retardation of patients with depression, the visual search paradigm was used in this study. The emotional expression (happy, sad) and neutral expression were used as interdependent or search targets in this paradigm. Subjects were asked to search the target face form a matrix containing 16 emotional faces after watching the target face. The measurement indices of the...
Today, power systems face new challenges in different fields, such as economic, social, environmental and technical. In the technical field, a number of issues related to protection systems are recognized, due to the inclusion of distributed generation and microgrids, among other aspects. This paper presents a novel laboratory experience aimed at university students, with the objective of understanding...
Unnecessary obstacles limit learning in cognitively-complex domains such as computer programming. With a lack of appropriate feedback mechanisms, novice programmers can experience frustration and disengage from the learning experience. In large-scale educational settings, the struggles of learners are often invisible to the learning infrastructure and learners have limited ability to seek help. In...
Generating and maintaining REST API documentation with usage examples can be a time consuming and expensive process for evolving APIs. Most REST API documentation tools focus on automating the documentation of the API objects, but require manual effort for capturing usage examples. Consequently, REST API developers need to know the cost vs. benefit of providing usage examples in the documentation...
In this poster, we describe The Social AR Continuum, a space that encompasses different dimensions of Augmented Reality (AR) for sharing social experiences. We explore various dimensions, discuss options for each dimension, and brainstorm possible scenarios where these options might be useful. We describe a prototype interface using the contact placement dimension, and report on feedback from potential...
One of the recent advances in ceramic tile industrial production is the introduction of ink-jet printers. Ink-jet printers are used for face texture printing in the biscuit tile production stage. This enables production of various ceramic tiles. Different textures and images can be used as the face of the tile. Because of this advance in automatic tile production, it is possible to introduce new methods...
We propose ‘Hide-and-Seek’, a weakly-supervised framework that aims to improve object localization in images and action localization in videos. Most existing weakly-supervised methods localize only the most discriminative parts of an object rather than all relevant parts, which leads to suboptimal performance. Our key idea is to hide patches in a training image randomly, forcing the network to seek...
Omnidirectional images describe the color information at a given position from all directions. Affordable 360° cameras have recently been developed leading to an explosion of the 360° data shared on social networks. However, an omnidirectional image does not contain interesting content everywhere. Some part of the images are indeed more likely to be looked at by some users than others. Knowing these...
In this paper, we propose a computational modeling method to investigate head-eye coordination in face-to-face behavior. The method looks into probability density of individuals' head orientation during looking at others' face. We conducted experiment under two different scenarios in human-human interaction. Under each scenario, individuals' head orientation could be fitted with one Gaussian distribution...
Facial wrinkle is one of the most prominent biological changes that accompanying the natural aging process. However, there are some external factors contributing to premature wrinkles development, such as sun exposure and smoking. Clinical studies have shown that heavy smoking causes premature wrinkles development. However, there is no computerised system that can automatically assess the facial wrinkles...
Low-shot visual learning–the ability to recognize novel object categories from very few examples–is a hallmark of human visual intelligence. Existing machine learning approaches fail to generalize in the same way. To make progress on this foundational problem, we present a low-shot learning benchmark on complex images that mimics challenges faced by recognition systems in the wild. We then propose...
Face alignment has witnessed substantial progress in the last decade. One of the recent focuses has been aligning a dense 3D face shape to face images with large head poses. The dominant technology used is based on the cascade of regressors, e.g., CNNs, which has shown promising results. Nonetheless, the cascade of CNNs suffers from several drawbacks, e.g., lack of end-to-end training, handcrafted...
The purpose of this research is to develop the real-world captioning system to ensure information accessibility for person with hearing impairment. However, switching the visual line between the speaker's face and the caption when one is engaging in conversation may stress the user. In this paper, we propose the real-world captioning system which display the dialog next to the speaker's face using...
Automatic kinship verification from facial information is a relatively new and open research problem in computer vision. This paper explores the possibility of learning an efficient facial representation for video-based kinship verification by exploiting the visual transformation between facial appearance of kin pairs. To this end, a Siamese-like coupled convolutional encoder-decoder network is proposed...
2D Gabor filters are sinusoidal waves of some frequency and orientation within a 2D Gaussian envelope and are used to model simple cells (S1) in primate visual cortex. Visual system in primates extracts information both in 2D spatial and frequency domains. In this paper, we use multiple spatial frequencies to model S1 cells in primates visual cortex. Thereafter, we use MAX and STD operators to extract...
The usage areas of biometric systems are becoming widespread in today's technology. Face recognition systems among biometric systems; Ease of use, reliability, cost, etc., the preference between public institutions, commercial enterprises and researchers is increasing. In this study, it is suggested that students should use face recognition system instead of traditional methods of absenteeism in education...
Although point cloud data (PCD) are easily measured using a RGB-Depth sensor such as Kinect and Xtion, measured PCD have undesirable noise and fluctuation of values. In this paper, a curved surface fitting method using a raster-scanning window is proposed to smooth original organized PCD with noise. The method allows PCD to be fitted to numerous small quadratic curved surfaces and to be smoothed while...
Victims of and witnesses to crime are asked to describe an offender using cognitive interviewing techniques (CI), before constructing a visual likeness of the face. The aim of the current experiment was to investigate whether composite construction using the EvoFIT holistic system would benefit from the parallel use of three enhancement techniques. The study manipulated the type of interview used...
Visual saliency modeling is becoming important and challenging for many scientific disciplines (robotic systems, psychophysics, cognitive neuroscience and computer science). Proposed model indicates possible salient regions by taking into consideration face presence and motion which is essential in motion pictures. By combining face presence and motion we can obtain credible saliency map with low...
