Leak of memory

[Aramis7609]

After many 'call' to "imagesearch" i got the error message :

pos = imagesearch(nom_xxx, PREC_yyy)
File "......", line nn, in imagesearch
res = cv2.matchTemplate(img_gray, template, cv2.TM_CCOEFF_NORMED)
cv2.error: OpenCV(4.1.1) C:\projects\opencv-python\opencv\modules\core\src\alloc.cpp:72: error: (-4:Insufficient memory) Failed to allocate 14133848 bytes in function 'cv::OutOfMemoryError'

From my point of view, this memory leak is due to opencv cv2.
Then this problem is solved by adding the following lines of Python code in "imagesearch" :

import gc # import the garbage collector, at the beginning
.................... def imagesearch(image, precision=0.8):
....................
....................min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res)
del img_gray # free memory
del template
del res
gc.collect()
del gc.garbage[:]

Then , there is also about the same problem with "click_image".

del img_gray # free memory
del template
del res
gc.collect()
del gc.garbage[:]

Thank you for this!
