Orientation and mobility are tremendous problems for Blind people. Assistive technologies based on Global Positioning System (GPS) could provide them with a remarkable autonomy. Unfortunately, GPS accuracy, Geographical Information (GIS) data map-matching techniques adapted to vehicle navigation only, fail in assisting pedestrian navigation, especially the Blind. In this paper, we designed an assistive device GIS, fusion of vision positioning. The proposed may improve user positioning, even...
Finding ones way to an unknown destination, navigating complex routes, finding inanimate objects; these are all tasks that can be challenging for the visually impaired. The project NAVIG (Navigation Assisted by artificial VIsion and GNSS) is directed
This paper discusses some new suggestions for designing hardware vision systems that take inspiration from spike-based biological image processing. The key idea is to modify already existing Address Event Representation (AER) designs so there a periodic reset signal can be generated every time predefined proportion of "neurons" has emitted spike. Each "neuron" only emits at most one spike per processing cycle, but the strongly activated neurons fire first, ensuring information about...
In eye-tracking experiments with primates, infants or non-cooperating subjects, the data used during calibration step generally suffers from high contamination. This contamination typically behaves as clusters, corresponding to periods in which subject was not actually looking at target. this type of multimodal samples, most techniques estimate central point distribution usually fail, resulting errors when mapping gaze camera screen coordinates. manuscript, we analyze viability using...
Certain key stimuli such as animals or human faces can trigger very fast saccades from early 100 120 ms after image onset (Crouzet et al., J Vis, 2010). Can be seen to other more conventional visual stimuli? Here we directly compared the speed and accuracy of targets defined by either color orientation. We presented four circular grating patches at equal distances fixation for 400 ms. There were different colors (red, green, yellow blue), orientations (vertical, horizontal, left right...
We propose in this work a new method for estimating the main mode of multivariate distributions, with application to eye-tracking calibrations. When performing experiments poorly cooperative subjects, such as infants or monkeys, calibration data generally suffer from high contamination. Outliers are typically organized clusters, corresponding time intervals when subjects were not looking at points. In type multimodal most central tendency measures fail principal fixation coordinates (the...
