c++ - How to get the pixel points of the contours? -

How do I get pixel points in contour? Suppose I have an image in which there are 5 configurations after findContours , I know that we can wipe the shape with the drawContour function, but I can use pixel points Know that the contour form

For example: 

  cv :: medianBlur (img1, img1,7); Cannie (src1, img1,250,350,3); Imshow ("abc", img1); Of vector & lt; Of vector & lt; Point & gt; & Gt; Figure; FindContours (IMG1, Profile, CV_O.T.F.A.T.NL, CV_CHAN_APPRX_NON); For (int i = 0; i   
 I did this and got this image, now I want to contour the pixel number, for example  (x1, y1) ,  (X2, y2) ,  ...  How do I get those information? here,   
 
 
 Contour is a 2D code  dot  dot . Therefore, to reach each point you can use 2  for  loops (the code displays the xy co-direction of each point with the contour ID), as shown below - (Int j = 0; i & lt; contours.size; j ++) for <
    (for int i = 0; i & lt; contours.size; i ++) Cout & lt; & Lt; "Id =" & lt; & Lt; I & lt; & Lt; "(" & Lt; <> contours [i] [j] .x   
 To better understand the data, you can actually reduce the number of digits in contour using the  approxPolyDP  check the documentation.

I'm trying to call the Python using the Java program py4j . I've been installing the plug-in Eclipse and test name Piidvi project.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

C++ Array Type Not Assignable in Copy Constructor -

-
I have a simple class that represents the triangle, which consists of three arrays square triangle {public: double x [3]; Double y [3]; Unsigned four colors [3]; }; I want to create objects in this square on the heap, then pass on those functions which will use the value from the array. Since I am in these items, I need to make a deep copy to make a copy. Triangle (const triangle and obj) {X = new double [3]; Y = new double [3]; Color = new unsigned char [3]; For (int i = 0; i I keep the following error: "Error: array type 'double [3]' is not assignable for each of the three arrays. I am taking the same view as discussion, and I do not know why I am unable to create a new array. The answer is also the same approach. Does anyone have any insights? Looks like I'm really stupid. I'm taking the same approach as discussed in this video. In the video, you can see that he started the array Read on the member-preliminary list and how it is dif...
