The recognition of places by using visual information in underwater environments is important when performing autonomous robotic exploration of the same area at different periods of time. It helps the robot to know its location and take decisions accordingly. However, vision-based recognition of underwater places can be a very challenging task due to the inherent properties of this kind of places...
Dermoscopy is the in vivo technique of skin surface microscopy which is frequently used in visual examination of the skin. With the rise in the usage of smartphones, many smartphone attachments have been developed that enable dermoscopy on a phone but these attachments are very expensive and are available only for high-end phones. We have developed a novel 3D printed clip-on that can convert any smartphone...
This paper presents a method for assess the risk index in a power transformers park, risk index is a metric that allows park administrator to ensure an optimal physical asset management, allocating properly financial and human resources in operation and maintenance actions. Assessing risk index requires calculating two secondary sub-index termed failure probability and consequence factor. Those indexes...
Programmers of all experience levels attempt to leverage code snippets with varying success, often as reminders or to learn new skills. To date, little work has explored the specific elements within code snippets that are challenging for novices. Comparing how novices and experts recall code snippets may expose what code elements programmers focus on and inform new approaches for improving examples...
This paper is devoted to investigation of features that will be the most appropriate for description of high resolution satellite imagery. We developed an image description model which is based on the distribution of image object classes. Proposed model could be used for image similarity estimation.
Assembling is an essential part of the Learning Objects paradigm from its beginnings. There are currently many methodologies that are aimed at automating part or all the assembly process. In this paper, we present a case study in which a specific Learning Objects assembly methodology was applied. To carry out this process an Assembly System, called ELO-Tool, was used. The results obtained are analyzed...
Currently, and increasingly, education uses technology to support teaching and learning processes, the present work shows a system to determine the best instructional techniques, taking into account students' learning styles, using a modification of the Felder and Soloman test. This modification, called FuzzyILS, was performed by Silva, Vicari and Ponce in 2016, and proposes the fuzzy of Felder and...
The Marrakech Treaty (MT) is a milestone in the relationship between copyright and human rights, is the first international treaty to be established with the exclusive objective of protecting cultural rights. This article details the most relevant aspects of the Treaty, its impact on the development and implementation of Accessible Educational Resources Repositories, and describes exceptions and limitations...
Passive acoustic recording has great potential for monitoring soniferous endangered and cryptic species. However, this approach requires analysis of long duration environmental acoustic recordings that span months or years. There is a variety of approaches to analysing acoustic data. However, it is unclear which approaches are best suited for monitoring of endangered species in the wild. Specifically,...
Nowadays, stereoscopic images are commonly used for 3D image generation, these are composed by a pair of images viewed independently by each eye, which creates a feeling of immersion and in depth perception. 3D vision technologies have multiple applications in many different areas such as medicine, entertainment, computer vision, etc.; being accessible to a wider group of people. However, there is...
As an emissive display, the organic light emitting diode (OLED) endure an indispensable role on the market growth of consumer electronics. Despite the preferable power efficiency, the active matrix OLED (AMOLED) displays still consume large energy. To adaptively increase the power efficiency of AMOLED displays, we propose an adjustable pixel dimming algorithm based on the structural similarity metric...
Visual induced motion sickness (VIMS) is one of the most effective factor of visual discomfort on wide screen such as 4K display. Though Biosignal parameter such as LF/HF wasn't reflect the VIMS enough considering individuality, we focus body motion effects that caused by VIMS itself. From the experimental result, the disturbance of body motion reflect time-sequence discomfort and might be possible...
It is known that the Sense of Agency is related to time lag between sensory feedbacks including vision and their causal movements. Most of previous studies about the Sense of Agency evaluated effects of time lag to the Sense of Agency on a single movement like pushing a button. The effects of the lagged visual feedback to the Sense of Agency on a continuous movement, however, were still unclear. The...
Gas source localization (GSL) is one of the most important and direct applications of a gas sensitive mobile robot, and consists in searching for one or multiple volatile emission sources with a mobile robot that has improved sensing capabilities (i.e. olfaction, wind flow, etc.). This work adresses GSL by employing a teleoperated mobile robot, and focuses on which search strategy is the most suitable...
The correcting process for strokes extracted from Chinese characters is the necessary step to extract the errors of writing errors automatically. Visualization of extracted strokes is the prerequisite for manual correction. Therefore, visualization and adaptive correction methods are proposed. To reduce the cognitive burden of correcting, color, brightness, saturation and order number is comprehensively...
In order to evaluate the recovery effect of the visible light band in the low-altitude remote sensing, the sensitivity and significance of the visual perception of the restored image are selected and optimized by the perceptual characteristics of the human visual system. Finally, the effective detail retention ability, Structure information, multi - scale similarity and visual fidelity. A kind of...
In the present work, a path following control for assistance robots is designed. The driver is designed to help blind people reach a destination through a path. This work is on the premise that person must choose the moment when the robot has to move due to it is using as support. Plus a linear velocity is generated an angular velocity which guides the person along the path, whenever the movement...
In this paper we describe a cyberspace of scientific papers, in which the most cited and significant documents are represented by a large size and the distance between documents is proportional to their semantic similarity. A new measure of semantic similarity of documents is proposed that is determined by the maximum correlation between explicit and implicit connectivity of the documents. A new science...
To examine the hypothesis that subjects who assign importance to the product selection criteria included in a commercial's message pay more attention to the message than do subjects who do not assign importance, an eye-tracking experiment was conducted. Commercials and websites with “reducing body fat,” “low in calories,” and “beneficial for dieting” messages were shown to 81 college students and...
Aiming at the performance evaluation on image captioning and video captioning, this paper discusses the existing performance metrics and then suggests a novel overall performance metric based on grey relational analysis of Grey System Theory. In our metric, all the available performance metrics of each captioning model is used to extract a comparative sequence. Meanwhile, a reference sequence is constructed...
