Even a small 28x28 image is composed by 784 pixels. identify face --- identify eyes ---blob detection ---- k-means clustering for left and right ---- LocalOutlierFactor to remove outlier points -----mean both eyes ----- percentage calculation ------. For example, it might be something like this: It would mean that there are two faces on the image. My github is http://github.com/stepacool/ you can find eye tracking code here that uses some advanced methods for better accuracy. If not for them, the program would crash if you were to blinked. Now, if we try to detect blobs on that image, itll give us this: And since that was originally our eye image, we can draw the same circle on our eye image: Believe it or not, thats basically all. Figure 5: Top-left: A visualization of eye landmarks when then the eye is open.Top-right: Eye landmarks when the eye is closed.Bottom: Plotting the eye aspect ratio over time. Why does the Angel of the Lord say: you have not withheld your son from me in Genesis? Weather 15 September 2021, I mean when I run the program the cursor stays only at the top-left of the rectangle and doesn't move as eyes moves. It needs a named window and a range of values: Now on every iteration it grabs the value of the threshold and passes it to your blob_process function which well change now so it accepts a threshold value too: Now its not a hard-coded 42 threshold, but the threshold you set yourself. But many false detections are. You can find how to set up it here. . Something like this: Highly inspired by the EAR feature, I tweaked the formula a little bit to get a metric that can detect opened/closed mouth. this example for version 2.4.5: Thanks for contributing an answer to Stack Overflow! maxRadius: Whats the max radius of a circle in the image. All thats left is setting up camera capture and passing its every frame to our functions. Thats good, now we supposely have the iris. What do you mean by "moves the cursor on one angle" ? To do that, we simply calculate the mean of the last five detected iris locations. Lets just create a variable that defines the mouse position and then set it each time the iris position changes: As you can see, Im taking the difference of position between the current iris position and the previous iris position. sign in How is "He who Remains" different from "Kang the Conqueror"?
