问题 I want to detect 4 basic hand gestures of user in front of camera. When the user moves his hand in front of camera from left to right, right to left, top to down and down to top. How can I achieve this using BoofCV for android? What are the starting steps? 回答1: This question is a bit high level and is really a generic computer vision question. BoofCV contains the tools so that you could do that using several different techniques. It doesn't contain gesture recognition built in. If the

问题 I've a Sprite that animates via texture array, with spinLeft being increasing the array index, and spinRight decreasing the index, as shown in the answer to my other question here: https://stackoverflow.com/a/44792902/6593818 The animation is working fine, but now I am trying to control the animation via a gesture recognizer or some other form of input. In the referenced question, the spin function has an input for speed (the TimeInterval), so I just need an output from a gesture recognizer:

问题 I'm looking for an algorithm for detecting simple shapes as rectangles, triangles, squares and circles, from a given set of (x,y) points. I'm also looking for a way of, once detected, transform the path to a more clean shape. I've scrambled the internet but haven't found any "simple" approaches. Almost all of them are way to advanced for my simple implementation. Thanks in advance. 回答1: On detection: There are most likely no simple general approaches for classifying any set of points into a

问题 I am using ScaleGestureDetector to detect pinch out and pinch in actions, by getting the scale factor an if it is less then one then it is zoom out and vise versa. But the problem is that on Android 6.0 the scale factor is always 1.0 which make it impossible to distinguish pinch in from pinch out. Thanks in advance for any help. import android.content.Context; import android.os.Handler; import android.support.v4.view.GestureDetectorCompat; import android.support.v4.view.MotionEventCompat;

问题 was trying to add this "gesture" function to my first program, and almost every search I did came to this thread: Fling gesture detection on grid layout I was able to get it working.. but in my case, I am not sure if it's 100 % correct. In my layout, I have 3 horizontal linearLayouts, each one has 5 buttons.. so it's 3 columns of 5 buttons.. according to the thread I had to: "Attach your gesture listener to all the views you add to the main layout;" that means for all the 15 buttons: "button

问题 Basically I want to replicate the spinning of a globe. In the real world you'd put your finger on the globe and and move it to the right and while you are moving your finger the globe spins to the right. On an iPhone it's not that simple... It could be something as simple as a finger comes down on the screen and point X is grabbed and then when the finger moves one pixel to the right the globe spines one frame to the right and the origin changes to the new spot. Then if the finger moves back

问题 Now i understand we can have 5 touch points by default in iPhone and have varied touch points enabled onto the different SDKs. However i have accomplished registering the touch points and getting distances, actual number of touch points. I would want to know if there's a way to accomplish and get the Diameter of a particular touch point for e.g. calculating the thumb touch in comparison with the index finger, Any ideas? 回答1: I think Apple makes it fairly clear that they don't intend to give
