Adjusting settings for the best results
Eye Precision allows for analysis of videos recorded in a variety of different methods
For this to work some video properties are adjustable within the app, namely "Contrast" and "Exposure". There is also a pupil threshold - the maximum "brightness" that the pupil can be and still be recognised
Contrast is the difference between dark and light colours on the video. In most cases it is advisable to keep this close to default for videos recorded with a smartphone, and to a very high setting for Vesticam or Vestibular First recorded videos
Exposure is the general level of lightness of the video. In most cases it is advisable to set the exposure low
In general, a darker pupil give the best results
Pupil threshold is set automatically after the pupil is marked by the user. This setting should work in most circumstances
If the light level changes during the video, it may be necessary to increase or decrease the pupil threshold manually. Increasing the pupil threshold allows for a brighter pupil to be tracked, while decreasing the threshold helps to exclude other non-pupil areas from being considered as a potential pupil, speeding up processing and giving more reliable results
Eye Precision Basic has preset settings to allow for solid results with any video recorded with infrared recording goggles
