I've considered that, but it's important to have as large view by of separate "beetles" as possible. I presume, the prob

Thank, it worked out. Also, since the reason is misplaced output, unrelated to opencv lib, there is no need to keep it here anymore, since it will only obstruct QA section view.

I'm sorry. I just wanted to keep description concise. Now I've completed it with details.

2017-08-06 09:05:36 -0600 asked a question Contour concatenation

I'm currently required to get contours of object from photo and initial steps are mentioned below. I've applied adaptive threshold (single channel uint8, black background output) on image and tried to remove all small debris with erosion, but some of them are left remaining. As next step, I've presumed, that, due to larger length, contours of required lines could be discerned and redrawn from zero on blank image of the same size, whereas redundant ones not. The encountered trouble is how could I concatenate their (single contours') arrays in a proper list to draw? Questioned part of Python code is lower:

im, contours, hirarchy=cv2.findContours(eroded,
                                    cv2.RETR_TREE,
                                    cv2.CHAIN_APPROX_SIMPLE)
for a in contours:
    b=cv2.arcLength(a, False)
    cnt2=[]
    if b>aver:
        cnt2.append([[a]]) #Required list
    else:
        pass
drawncnt=cv2.drawContours(n,cnt2,-1,
                      (255,255,255),1) #Execution error here
