10th Invited Seminar Professor Nojun Kwak , Professor of Seoul National University talks at Computer Vision & Graphics Seminars organized as department colloquium on Apr. 22nd. Title is "Introduction to convolutional neural networks". Abstract: In recent 5 years or so, deep learning, especially, deep convolutional neural networks (CNN) are very successfully applied to various areas dealing with moderate to big sized data. In this talk, I will briefly review the history of machine learning during the last half century and introduce the deep CNNs. The driving force that led the success of CNNs such as ReLU (retified linear unit), weight sharing, and dropouts are explained and how state-of-the-art performances on various machine learning problems could have been achieved by deep CNNs. 2016.5

9th Invited Seminar Professor Jongwoo Lim , Dept. of Computer Science and Engineering, Hanyang University talks at Computer Vision & Graphics Seminars organized as department colloquium on Apr. 22nd. Title is "Computer Vision Technologies for ADAS and Autonomous Driving". Abstract: One of the ultimate goals of Computer Vision research is to understand the scene from images or videos. Geometric perception of the scene structure is essential to semantic understanding, and it is also critical for robot navigation and operation tasks. In this talk I will present an overview on visual SLAM(simultaneous localization and mapping) and recent advances in metric-topological mapping and line-based location recognition. Metric-topological mapping is designed to handle the map update problem in loop closure, which separates global adjustment from local updates. Lines are useful features in man-made environment, and motion estimation and location recognition using line features are presented. 2016.4

8th Invited Seminar Professor Gunhee Kim , Dept. of Computer Science and Engineering, Seoul National University talks at Computer Vision & Graphics Seminars organized as department colloquium on Mar. 25th. Title is "Connecting Vision and Language via Online Blog Posts". Abstract: Recently there has been a hike of interest in jointly understanding images and natural language text in the research of computer vision, natural language processing, and machine learning. In this talk, I will introduce three projects of our research toward this direction. First, I will discuss how to jointly summarize large collections of blog posts and photo streams for the exploration of Web data. Second, I will present our results for ranking and retrieval of image sequences from a natural language text query, consisting of multiple sentences or paragraphs. Finally, I will introduce an approach for generating a sequence of natural sentences for a photo stream using a novel architecture of multimodal neural networks. 2016.3

7th Invited Seminar Professor Seung-Won Jung , Dept. of Multimedia Engineering, Dongguk University talks at our Computer Vision & Graphics Seminars on Feb. 6th. Title is "Joint Color/Depth Image Enhancement Techniques". Abstract: Color image enhancement such as contrast/sharpness enhancement and spatial/temporal resolution enhancement has been extensively studied. Meanwhile, recent advances in computer vision algorithms and image sensor technologies enable us to estimate or capture high quality depth images in real-time, which necessitate depth image enhancement techniques. Instead of individual enhancement of color or depth image, many research efforts have been made for the joint use of color and depth images. In this talk, I will first review conventional color image enhancement methods that use the depth image in addition to the color image. The methods on the opposite direction, i.e., depth image enhancement methods that use the color image in addition to the depth image, will also be presented. Finally, I will introduce my research results on this joint color/depth image enhancement. 2015.2

6th Invited Seminar Dr. Hwasup Lim, Senior Research Scientist at Imaging Media Research Center (IMRC), Korea Institute of Science and Technology (KIST) talks at our Computer Vision & Graphics Seminars on Nov. 28th. Title is "RGBD Image-based Surface Tracking and Mapping". He received his Ph.D. degree in Electrical Engineering from the Pennsylvania State University in 2007. He was a R&D staff member at Advanced Media Lab, Samsung Advanced Institute of Technology (SAIT) from 2007 to 2011, where his research focused on TOF depth image processing and 3D human modeling & tracking. He is currently a senior research scientist at Imaging Media Research Center, Korea Institute of Science and Technology (KIST). His research interests include RGBD image-based 3D modeling, hand tracking, and object recognition. 2014.11

4th Invited Seminar Dr. Ouk Choi, research scientist of Samsung Advanced Institute of Technology, talks at our Computer Vision & Graphics Seminars on Oct. 10th. Title is "ToF Depth Image Quality Enhancement". He received Ph.D degree at Korea Advanced Institute of Science and Technology (KAIST). In this talk, he introduces his efforts to improve the quality of depth measurements provided by time-of-flight cameras. Due to phase wrapping, time-of-flight cameras deliver shortened or wrapped depth measurements if their corresponding scene points are beyond a certain maximum range. By unwrapping the depth measurements, he can recover the distorted scene structure. The pixel areas of time-of-flight cameras are designed to be wider than that of conventional cameras. Thus depth maps acquired by time-of-flight cameras are low in resolution. The second part of his talk describes a method for increasing the spatial resolution of a depth map using its corresponding high-resolution color image. 2014.10

2nd Invited Seminar Dr. Seong-Jin Kim, research scientist of Institute of Microelectronics, Singapore, talks at our Computer Vision & Graphics Seminars on June 19th. Title is "Integrated Microsystems for Detection and Recognition of Natural Signals". He received Ph.D degree at Korea Advanced Institute of Science and Technology (KAIST) in 2008 and worked for Samsung Advanced Institute of Technology till 2012. His research interests are Integrated imaging system, CMOS sensors, range finder, and biomedical interfaces. This talk briefly presents integrated circuit based microsystems to detect various natural signals and their special features. Advanced transducers implemented in small platform to convert analog natural signals to digital and recognize important features without complicated processing, allowing electronic devices to communicate with human. 2014.06
