Advances on cognitive automation at LGI2P / Ecole des Mines d'Alès Doctoral research snapshot 2014-2015 July 2015 Research report RR_15_01
Foreword This research report sums up the results of the 2015 PhD seminar of the LGI2P lab of the Alès National Superior School of Mines. This annual day-long meeting gathers presentations of the latest research results of LGI2P PhD students. This year edition of the seminar took place on June 25th. PhD students presented their work for the past academic year. All presentations were be followed by extensive time for very constructive questions from the audience. The aggregation of abstracts of these works constitute the present research report and gives a precise snapshot of the research on cognitive automation led in the lab this year. I would like to thank all lab members, among which all PhD students and their supervisors, for their professionalism and enthusiasm in helping me prepare this seminar. I would also like to thank all the researchers that came to listen to presentations and ask questions, thus contributing to their thesis defense training. I wish you all an inspiring reading and hope to see you all again for next year’s 2016 edition ! ! Christelle U RTADO

D e s igning an int e rfa ce adapt e d to vi s ually impair e d: c olorim e tri c c hara c t e rization of di s play s and g e n e ration of appropriat e imag e Imad Benkhaled, Isabelle Marc, Dominique Lafon-Pham Introdu c tion 1 The view is probably the sense which we attach the most importance, but the disease, the aging and accidents can cause degradation or total loss of sight. Current technological developments give hope that we can provide assistance to the visually impaired to assist in the tasks of daily living, including using virtual reality. In fact, virtual reality knows a major boom in recent years in the world of video games; headsets allow immersing themselves in an entirely imaginary world. But virtual reality is used also for design in fields such as architecture, automotive, etc. We present below the context in which the work of this thesis take place, namely a design project of technical assistance for the visually impaired based on the use of virtual reality. Then we recall some notions about color spaces, since the way to encode the images, which is to say to present data, will have a great influence on the efficacy of processing. We will explain why we seek to precisely control the photometric characteristics of the images displayed with the calibration of the displays. Next, we present an image processing example can provide a solution to a problem faced by people living with the diseases that concerns us. 2 Cont e xt e Our team is working on the implementation of technical assistance for the visually impaired which is composed of an image acquisition system (camera), an image processing system, and a display system (virtual reality glasses). We consider a visually impaired user: an environment image is captured by the camera; the image is processed to make it more easily understandable and usable by the visually impaired, and finally displayed on the screens of virtual reality glasses. The aim of this thesis is the definition of the specific image processing for each kind of vision impairment. Specifically, we try to help persons with retinitis pigmentosa and glaucoma. Other teams are working on similar projects; these include the work of E.Peli and his team uses a method of enhancing contours, the contours are detected on the images using statistical methods [1]. Veringham et al performs a semantic analysis and a segmentation of images, the identified objects being highlighted by changing their color [2]. 3 Phy s i c al c hara c t e rization of th e e quipm e nt We currently use for our prototype Wuzix Wrap 1200VR Virtual reality glasses, equipped with LCD screens, and Logitech cameras. This choice is not final, and we need software ������
