Re: [visionlist] Size (vertically & horizontally) of the human visual field (total across two eyes vs. binocular vs. one eye)

Dear Hans and Les,

Greetings from Plymouth!  

Traquair’s book cites Rønne (“Zur Theorie und Technik der Bjerrumschen Gesichtsfelduntersuchung”, Arch f Augenheilkunde, Bd 78, Heft 4, 1915 – does anybody have this??), and on page 9 of the 6th edition (1949) reprints Rønne’s table. This is where the 107 degrees come from. So, Rønne may be the more appropriate reference. He has a nice biography in the  BJO (open)… http://ift.tt/1JDlZQt

Best wishes to all

Paul

Re: [visionlist] Size (vertically & horizontally) of the human visual field (total across two eyes vs. binocular vs. one eye)

Dear Les,

I second your question. These numbers about visual field size appear
everywhere but no original source is given. Books cite books cite books.
When we wrote our review on peripheral vision (2011), I went to the
obvious sources, standard perimetry books, and took the temporal 90° in
the graphs at face value, assuming that that must be the maximum since
rays are then tangential to the frontal corneal surface. I forgot about
refraction and also did not notice the 90° were an artifact of the
cupola perimeters then in use (modern cupola perimeters show even less).

OK too late now. Please beware, that the temporal extent is wrong
in our review:

The English Wikipedia (“Visual Field”) is no help either. It states “100
degrees temporally”
citing Spector’s (1990) book, which in turm cites Glaser (1978),
Harrington (1971), and Miller et al., (1985), all books. Spector’s book

In it, the visual fieldsize is Chpt. 116which states

[visionlist] Rovereto Attention Workshop 2015

We are pleased to announce the fifth edition of the Rovereto Attention Workshop – RAW 2015.

WHERE and WHEN: The workshop will be held in Rovereto, Italy on November 5-8, 2015.

WHAT: The topic of RAW 2015 will be “Attention and Brain Fluctuations”.

Deadline for poster submission: October 2nd. Five awards for non-faculty are available

Workshop website: http://ift.tt/1PkQSyv

The goal of RAW is to provide a unique forum for researchers from a range of perspectives to come together to discuss their research and develop new directions and collaborations. The workshop differs from larger conferences in so far as there are a small number of speakers (all invited) and there are no concurrent talks. In addition to the individual talks, there will be a poster session for students, post-docs and young researchers to present their work. The workshop is hosted by the CIMeC (Center for Mind/Brain Sciences), University of Trento.

The workshop has a limited number of available places. Potential attendees are encouraged to register online as soon as possible.

Invited speakers:

Tim Buschman, Princeton University, USA

 

Ole Jensen, Radboud University Nijmegen NL

 

Ayelet Landau, The Hebrew University of Jerusalem, IL

 

Kia Nobre, Oxford University UK

 

Charles Schroder, Columbia University USA

 

Catherine Tallon-Baudry, Ecole Normale Supérieure, FR

[visionlist] [CFP] Extended Deadline: Workshop on Deep Learning and its Applications in Vision and Robotics

Dear all,

due to requests we are extending the deadline for submission of contributions to October 10.

_IMPORTANT DATES_: * Papers due:       10 October, 2015 * Notification:        20 October, 2015 * Camera-ready:   5 November, 2015

 * Workshop:          1 December, 2015

 

================================================================Workshop on Deep Learning and its Applications in Vision and RoboticsTo be held in conjunction with AI 2015 and ACRA 2015 conferencesCanberra, Australia,1st December 2015http://Juxi.net/workshop/deeplearning-applications-vision-robotics-2015/================================================================CALL FOR PAPERS:Applications of deep learning have been proliferating at an astronomical rate in the recent times into various disciplines of engineering. The significant advancements that deep learning methods have brought out for large-scale image classification tasks have generated a surge of excitement in applying the techniques to other problems in computer vision and more broadly into other disciplines of computer science, such as robotics. However, building deep learning algorithms for highly non-linear real-world problems such as those encountered in computer vision and robotics is non-trivial and requires substantial expertise. The goal of this workshop is to bring together researchers from Australia and Asia working in the field of deep learning to discuss recent advances, ongoing developments, and build collaborations by exchanging new ideas for future applications.TOPICS:We invite contributions spanning all areas of deep learning for computer vision and robotics. A special interest is in the applications of deep learning techniques to problems arising in “real world” settings of vision and control.The extended abstract submissions should be in IEEE Conference format and consist of no more than 4 pages (see the workshop website for submission details). Submitted papers will be peer-reviewed by multiple reviewers and low-quality papers will be rejected. Selected papers will form the basis for spotlight talks and poster discussions. The papers will not be archived; but we hope the presentations will generate discussions among the authors to improve their work and publish it elsewhere.IMPORTANT DATES: * Papers due:       10 October, 2015 * Notification:        20 October, 2015 * Camera-ready:   5 November, 2015 * Workshop:          1 December, 2015BEST PAPER PRIZE:Sponsored by nVidia, a GTX TITAN X Graphics Card will be awarded for the best paper.WORKSHOP WEBSITE:http://ift.tt/1L26YwT WEBSITE:http://ift.tt/1KPNO9O WEBSITES:AI 2015: http://ift.tt/1L26YwW 2015: http://ift.tt/1KPNQ1B TUTORIALS/SPEAKERS:
