Leather defect detection using semantic segmentation: A hardware platform and s...
Khanal, Salik Ram; Silva, Jorge; Magalhães, Luís Gonzaga Mendes; Soares, João; Gonzalez, Dibet Garcia; Castilla, Yusbel Chavez; Ferreira, Manuel J.Leather is a textile material made from the animal skins created through a process of tanning of hides. It is a durable material, and the price is higher compared to other types of textiles. The leather is highly sensitive to its quality and surface defect condition as it is expensive. The manual defect inspection process is tedious, labor intensive, time consuming, and often prone to human error. The aim of th...
Tracking 3D deformable objects in real time
Silva, Tiago; Magalhães, Luís Gonzaga Mendes; Ferreira, Manuel; Khanal, Salik Ram; Silva, Jorge3D object tracking is a topic that has been widely studied for several years. Although there are already several robust solutions for tracking rigid objects, when it comes to deformable objects the problem increases in complexity. In recent years, there has been an increase in the use of Machine / Deep Learning techniques to solve problems in computer vision, including 3D object tracking. On the other hand, sev...
Student engagement detection using emotion analysis, eye tracking and head move...
Sharma, Prabin; Joshi, Shubham; Gautam, Subash; Maharjan, Sneha; Khanal, Salik Ram; Reis, Manuel J. C. S.; Filipe, VítorWith the increase of distance learning, in general, and e-learning, in particular, having a system capable of determining the engagement of students is of primordial importance, and one of the biggest challenges, both for teachers, researchers and policy makers. Here, we present a system to detect the engagement level of the students. It uses only information provided by the typical builtin web-camera present i...
Facial image processing to monitor physical exercise intensity
Khanal, Salik RamOs avanços registados na tecnologia de visão por computador têm possibilitado a sua aplicação em várias áreas, incluindo as ciências do desporto. Nas últimas décadas várias tecnologias foram desenvolvidas para monitorizar a intensidade do exercício físico, no entanto ainda se sente a falta de técnicas confiáveis e não invasivas (contactless). Existem vários parâmetros medíveis para quantificar a intensidade do ...
