Visual Privacy Protection Using False Colors

Abstract:

Privacy protection in video surveillance is an important problem, and it will become even more important, as video surveillance is gains in popularity. However, simple methods for protecting privacy are not sufficient as they do not contain all the desired attributes that is expected from a good privacy protection algorithm. Privacy protected images must be reversible if the need arises to view them as unprotected (e.g., during a criminal investigation). Furthermore, protected image should not prohibit non-private statistics to be extracted. Also, the protected content should not be visually disturbing as it is the case with some of the existing privacy protection methods. Perhaps most importantly, the protection must be continuous: that is faces even in a single frame of a video should not remain unprotected. The algorithms that rely on computer vision techniques may therefore be vulnerable to this problem: if an algorithm fails to detect a sensitive region, it will remain unprotected.

In this seminar, methods that are commonly used for visual privacy protection will be reviewed and then a balanced method that was proposed in Ciftci's Ph.D. thesis will be mentioned. The proposed method is reversible, does not create disturbing outputs, do not prohibit collecting non-private information, does not rely on computer vision techniques.

Next Wednesday, Dr. Çiğdem Beyan (Istituto Italiano di Tecnologia) is going to give a seminar on Social Signal Processing (SSP) approaches, particularly for emergent leadership, for Multimedia Informatics - Research Methods (MMI 700) course. You are all kindly invited. Sorry for multiple copies.

Location: Conference Room (124), METU Informatics Institute
Time: December 27, 2017, 11:30-12:30

Abstract:

Social interactions are the main facet of human life and also the fundamental research area for social psychology. Even though psychologists have been working on social interactions for a very long time, the automatic analysis of them is a relatively new problem. Social signal processing (SSP) is the field which aims to analyze human interactions in an automatic way using the recent advances in machine analysis (e.g. speech processing, computer vision, machine learning). In this talk, I will survey some approaches and results regarding identification of the social interactions in small group meeting environments particularly for emergent leadership. In detail, a new corpus that has been collected using portable audio and video sensors, novel nonverbal features proposed and the computational methods used will be addressed.

Cigdem Beyan is a postdoctoral researcher at Istituto Italiano di Tecnologia (IIT), Pattern Analysis and Computer Vision (PAVIS) department since September 2015. In PAVIS-IIT, she has been working on social signal processing. She obtained her Ph.D. degree (2015) in School of Informatics, University of Edinburgh, UK, under supervision of Prof. Robert B. Fisher. Her thesis was a part of EU project (FP7) called Fish4Knowledge, in which she mainly investigated fish behaviour understanding. Prior to that, she received her MSc. degree (2010) in School of Informatics, Middle East Technical University where she worked on multiple object tracking and abandoned-object detection utilizing multi-modalities. Beyond her research background, she has a teaching experience (in Turkey and in UK) for 6 years. Additionally, she has been an Associate Fellow of the Higher Education Academy in recognition of attainment against the UK Professional Standards Framework for teaching and learning support in higher education since 2014. She contributed to the computer vision, machine learning and multimedia domains by being (co-) author of more than 25 research papers and has a PCT Patent Application to WIPO. She is a reviewer for various international journals such as Pattern Recognition, IEEE Transactions on Knowledge and Data Engineering and IEEE Transactions on Multimedia and for the conferences such as CVPR, ICCV, BMVC, and ICPR.

This Wednesday, Dr. Sertan Şentürk (soon to join the R&D team in Kobalt music) is going to give a seminar titled “What is Music Information Retrieval? Applications and the State-of-the-Art” for Multimedia Informatics - Research Methods (MMI 700) course. You are all kindly invited.

Abstract: What is Music Information Retrieval? Applications and the State-of-the-Art

Music, without a doubt, is one of the pinnacles of human creativity, communication and culture. With the digital media revolution and the rise of music streaming services, there has recently been a growing interest and a high demand to process large-scale musical material such as audio recordings, music scores and album reviews. In this talk, I will provide a gentle introduction to music information retrieval (MIR), an interdisciplinary field which “incorporates elements from signal processing, machine learning, psychology, musicology, and many more” to retrieve relevant information from music. From recommendation systems to automatic music generation, I will present a wide variety of examples involving MIR and discuss how such technologies are being used in academic and industrial settings, for example in music streaming, computational musicology and music education.

Bio
I am a data scientist, specializing in music information retrieval, soon to join the R&D team in Kobalt music. My research involves developing signal processing and machine learning based computational methodologies to automatically describe and discover music. Throughout the years, I have worked on creating robust and scalable solutions for a vast number of tasks such as audio-score alignment, automatic genre/mode classification, music structure analysis, and audio fingerprinting.

In February 2017, I obtained my Ph.D. degree in Information and Communication Technologies from the Music Technology Group in Universitat Pompeu Fabra, Spain. I received my MSc. degree in Music Technology from Georgia Institute of Technology, the USA in 2011, and my BSc. degree in Electrical and Electronics Engineering from Middle East Technical University, Turkey in 2009. I have also completed a four-year, part-time classical guitar program from Hacettepe University Ankara State Conservatory in 2009.

Health Informatics Department Research Assistant exam will be held on 22 December 2017  Friday at 10:00 in A Block 108. The names of the candidates who will enter the evaluation exam are as follows:

Title: Exploring Temporal Dynamics of Facial Behavior

Abstract: While the majority of earlier studies in face analysis rely solely on static appearance, temporal analysis of expressions reveals interesting patterns. By exploiting temporal patterns, the current state of automatic face analysis goes far beyond recognizing basic expressions and identity. Our recent findings show that the use of temporal dynamics of expressions can benefit a large variety of tasks from assessing mental health to the estimation of taste appreciation and the verification of kin relations. In this talk, I will discuss how we can capture and model discriminative temporal characteristics of expressions, leading to a more reliable analysis of facial behavior.
