Abstract

We introduce a new problem domain for activity recognition: the analysis of children’s social and communicative behaviors based on video and audio data. We specifically target interactions between children aged 1-2 years and an adult. Such interactions arise naturally in the diagnosis and treatment of developmental disorders such as autism. We introduce a new publicly-available dataset containing over 160 sessions of a 3-5 minute child-adult interaction. In each session, the adult examiner followed a semi-structured play interaction protocol which was designed to elicit a broad range of social behaviors. We identify the key technical challenges in analyzing these behaviors, and describe methods for decoding the interactions. We present experimental results that demonstrate the potential of the dataset to drive interesting research questions, and show preliminary results for multi-modal activity recognition.

Computational Photography MOOC on Coursera, comes to a close.

May 7th, 2013 Irfan Essa Posted in Computational Photography, Computational Photography and Video, Coursera, Denis Lantsman No Comments »

The Computational Photography MOOC offering in Coursera came to a close with the following final announcement (abridged here) on May 7, 2013.

Computational photographers:

Thanks for joining us for an engaging 5 weeks of collaboratively learning the wonderful aspects of computational photography. We bid you all farewell now and hope to see some of you in a future reincarnation of this class, building on the feedback provided by many of you. Keep a lookout for the repeat of the same class, and for another class continuing to more advanced topics.

Final graded scores, and the the certificate of completion will be made available this week. All assignment solutions are available, as requested. We will also keep the class site open for a while.

Do remember that we still welcome your feedback, so use the forums. If you haven’t done so already, please do spend a few minutes to fill out the survey for the last week of class, which is part of a survey we are conducting to understand and evaluate online classes offerings like this one.

Again, thanks for participating, and good luck with your future endeavors. And remember to take good pictures, and to have fun computing with photographs.

Coursera Course on Computational Photography, NOW LIVE and RUNNING!

March 23rd, 2013 Irfan Essa Posted in Computational Photography, Coursera, Denis Lantsman 6 Comments »

We are live!

Welcome to the course website!

As you take a look around, there are a few things we want to bring to your attention:

1. Do note that while this is an introductory class, we do require that you have working knowledge of college level mathematics, which includes concepts like Linear Algebra and Calculus. In addition, the programming assignments will require access to a computer with Python and OpenCV. Instructions for installing this software are available here, which is also linked in the navigation bar of the site. The responsibility to get your computer system working with this software is entirely yours. The diverse nature of computer platforms and softwares do offer challenges in setting up such systems and we encourage folks to use the forums to help each other with challenges faced.Please get started with the software installation as soon as possible!

2. These online courses are still rather mysterious, we want to learn as much as we can about them What works? What doesnt?. Accordingly, we invite you to participate in occasional surveys that are part of the research study. The surveys will tell us about you, and how the course is working for you. The information you provide will help us make the course better and improve our ability to provide more intellectually engaging content. Participation in the surveys is completely optional and will not affect your grade in the course in any way. For your reference, here is a link to a PDF document Consent Form that describes the surveys and study in more detail.If you would like to participate, begin by filling out the background survey here. Also, keep an eye on the syllabus page and the weekly announcements for end-of-week surveys.

3. The syllabus page will be updated every week to reflect all of the course content as it becomes available. Please consult that page if you are unsure about what to do next. The page also contains useful information about class logistics, policies, and frequently asked questions.

4. Note that the lecture videos page contains links to the subtitles, slides, and video file downloads for each of the lecture videos.Thank you for your attention, and I hope you will have fun in the following few weeks!

-Denis
