boundary

问题 This question already has answers here : jQuery/JavaScript collision detection (6 answers) Closed 3 years ago . I have two div elements. Each of them have 450px width and height. How do I check if the first div is overlapping the second div? I've tried to use javascript hittest, but it's a little bit complicated. Since I'm trying to find out how it actually work, I would like to get started with a simpler code. I found out that I can use .getClientRects to get the boundary of an element, but

问题 I hope someone can help, I've written a client to my spring webmvc app, for the client I am using jersey and the ApacheConnector. I need to keep the jsessionid and can't see how I can do that with jersey's HttpUrlConnector. I should also mention that before I needed to keep track of the session the file upload service worked with jersey's HttpUrlConnector. I know the spring webmvc file upload service works because my web front end is able to upload a file. Just for completeness it looks like

问题 As you may have already noticed, in the newer versions of matlab the boundary function (which computes the boundary for a set of 2d or 3d points) has been improved. Now it is possible to give the function a parameter called 'shrink factor'. If the shrink factor is 0, then the boundary traced is the traditional convex hull. The boundary is more shrinked when the shrink parameter is bigger. The default value for the shrink factor is 0.5, in case you don't specify any value. So, I understand its

问题 I've been working on trying to get boundary inputs working in a small game of mine. At first I got this error: Exception in Tkinter callback Traceback (most recent call last): File "/usr/lib/python3.2/tkinter/__init__.py", line 1402, in __call__ return self.func(*args) File "/home/ppppwn3d/workspace/Python/JailBreakBob/JailBreakBob.py", line 173, in buttonclick_gamescreen if entryx > 10 or entryx < -10 or entryy > 10 or entryy < -10 : TypeError: unorderable types: str() > int() So I realised

问题 Consider a kernel which performs vector addition: __kernel void vecAdd(__global double *a, __global double *b, __global double *c, const unsigned int n) { //Get our global thread ID int id = get_global_id(0); //Make sure we do not go out of bounds if (id < n) c[id] = a[id] + b[id]; } Is it really necessary to pass the size n to the function, and do a check on the boundaries ? I have seen the same version without the check on n . Which one is correct? More generally, I wonder what happens if

问题 This Pentagon example shows holes can be added inside a Polygon: http://code.google.com/p/gmaps-samples-v3/source/browse/trunk/poly/pentagon.html?r=40 I would like to add a hole inside a circle. Currently I am mimicking this by making a circle shape polygon and putting inner and outer bounds and it is working fine, however the code is extremely long seeing as the map has ~15 circles in it. Any help would be much appreciated Thanks! 回答1: I didn't find anything for the Circle class, but someone

问题 I currently have loaded a simple image onto a canvas. Its just a white circle with a black background. What I'm trying to do is convert that white area into a shape. This shape will then be used for boundary detection. I'm assuming that I need to loop through the image data pixel by pixel? I've done this before for color manipulation, but I'm not sure how I would go about saving this information into "in bounds" and / or "out of bounds". Other images used will be a bit more complex: Thanks!

问题 My question is simple. How do I make keras output to be limited with boundaries - min and max? Some people suggest me to make a custom activation function to converts the output to transform in min and max values. I want it to be my last option. I thought kernel_constraint and bias_constraint on Dense layer with min_max_norm will work but it turns out to be not working. 回答1: If you can sacrifice the linearity of the activation function, then this is easy, you can use Sigmoid to get between 0

问题 I've been trying to create a program that displays a ball in the center of a window, with 4 buttons titled Up, Down, Left and Right at the bottom. When you press the buttons the ball moves in the corresponding direction. I've got that part figured out, but I also need to figure out how to make it so if making the ball go in a certain direction obscures it from view, it stops it from going in that direction. I need to find a way to detect the boundaries of the window, and stopping the ball
