(LAPLACIAN MASK RESULT)(ENHANCED IMAGE)IMAGE SEGMENTATION Negative Laplacian OperatorPositive laplacian operatorINPUT IMAGE This Operator can be used to find edges in an image.It can be of two types:Positive laplacian operatorNegative Laplacian OperatorĠ-10 2. The Laplacian operator is an example of a second order or second derivative method of enhancement.It is particularly good at finding the fine detail in an image. Here image enhancement is done using laplacian operator. The principal objective of enhancement is to process an image so that the result is more suitable than the original image. Our objective is to track the gaze of an eye.We have been able to detect the eye for 3 directions that is left,middle and right.Here we have worked with still image.The complete workflow is as follows:ĮNTIRE PROCESS DONEInput ImageImage EnhancementImage SegmentationBinarizationMorphological OpeningImage CroppingIris DetectionIMAGE ENHANCEMENT In order to achieve this movement, the speed of the target should be in the range that can be handled by the human eye.įixations: These are the movements which stabilize the retina on the object of interest.Įlectro-Oculography Sceleral Search Coils Infared Oculography Video Oculography Smooth pursuits: These happen when the eyes are following a moving target. Saccades: These are rapid eye movements that are aimed at focusing the visual attention to a different object. The eye movements can be mainly classified into three categories. The light that enters the eye is refracted by the eye lens, and then it falls onto the retina layer which covers the inner surface of the eyeball, forming the image of what is seen through the eyes.EYE MOVEMENTS Iris controls the amount of light which passes through pupil. IMAGE FORMATIONĬornea lets the light inside of the eye, which passes through pupil.Īround pupil, we find the iris. The parts of the eye which are of interest for eye-trackers.

IS GAZE TRACKING USEFUL?Gaze tracking has a number of possible applications that is beneficial for the society.A new form of Human-Computer Interaction, that can help aiding the disabled.The technique can be used to detect when a driver is getting drowsy.It can be a tool for study of users visual behaviour when surfing the internet or for cognitive analysis.It finds application in medical research and for surveillance purpose.Recent application of Eye tracking involves the scrolling effect like when we move our eye up or down accordingly it will scroll up or down. What is it? Gaze tracking, as the name suggest, is tracking the gaze of a person.The objective of a gaze tracking system is to track the focus of the user's vision.So it is necessary to be able to track the eye first from which other information can be inferred.
