2016-04-09 06:17:38 -0500 asked a question Alternative library for image_slicer

I'm working with large tiff images (~~16k x 16k). I used slicing image for 9 tiles in my algorithm (library: image_slicer) before image processing.

I'm looking for some faster alternative method of slicing image for tiles. This one is so slow - when i open 4-5 images in once time, algorith slicing images for few minutes.

I tried to use img=img[x:y , x:y], but this method crashed my python application.

2016-03-30 02:56:00 -0500 asked a question OpenCV Error: Insufficient memory when i use template matching

I'm working in my programme with "huge" tiffs (8411x8361,60Mb). When i tried use template matching function on the unprocessed image, console showed me this kind of error:

OpenCV Error: Insufficient memory (Failed to allocate 140682288 bytes) in cv::OutOfMemoryError, file ......\sources\modules\core\src\alloc.cpp, line 52 OpenCV Error: Assertion failed (u != 0) in cv::Mat::create, file ......\sources\modules\core\src\matrix.cpp, line 424

I understand meaning of this error (I hope so), so i sliced my image for 4 tiles and use cutted part of my TIFF in template matching algorithm. Console showed me the same error message - of course with lower number of "failed to allocate X bytes".

Moreover, template matching is only one part of my programme. In previous steps it wasn't any problems with open,use and edit unprocessed huge TIFFs.

Any ideas?

It was loaded correctly. I can show it in grayscale and colour.

Additionally, this code works fine with "test.jpg", but doesn't work with TIF file

2016-03-12 10:30:14 -0500 commented question Template matching python error

My code, now:

image_dir='7_7026_polowa.tif'   
image = cv2.imread(image_dir)
..........
img_gray = cv2.imread(image_dir, 0)
template = cv2.imread('template.tif', 0)
w, h = template.shape[::-1]

res = cv2.matchTemplate(img_gray,template,cv2.TM_CCOEFF_NORMED)
threshold = 0.8
loc = np.where( res >= threshold)
for pt in zip(*loc[::-1]):
      cv2.rectangle(image, pt, (pt[0] + w, pt[1] + h), (0,0,255), 2)

 cv2.imwrite('res.png',image)

Ok, i corrected it, but now another error:

res = cv2.matchTemplate(img_gray,template,cv2.TM_CCOEFF_NORMED)
cv2.error: ..\..\..\sources\modules\core\src\matrix.cpp:424: error: (-215) u != 0 in function     cv::Mat::create
2016-03-12 04:52:11 -0500 asked a question Template matching python error

Hello, I would like to use this code in my programme:

img_rgb = image
img_gray = cv2.cvtColor(img_rgb, cv2.COLOR_BGR2GRAY)
template = roi
w, h = template.shape[::-1]

res = cv2.matchTemplate(img_gray,template,cv2.TM_CCOEFF_NORMED)
threshold = 0.8
loc = np.where( res >= threshold)
for pt in zip(*loc[::-1]):
     cv2.rectangle(img_rgb, pt, (pt[0] + w, pt[1] + h), (0,0,255), 2)

cv2.imwrite('res.png',img_rgb)

image and roi are the images (tiff format) readed in earlier part of my code

Now, i got error:

w, h = template.shape[::-1] ValueError: too many values to unpack (expected 2)

Where is the problem?!

Hello,

I found angle and scale invariant template matching code, but not for python language... Have anybody got it?

I will be very grateful !

Ok, i try again and it works now correctly. Thanks for all advices!

2016-02-22 16:35:08 -0500 commented question DLL load failed with opencv 3.1 and python 3.5

I see, that cv2.pyd file is not created in both places: in opencv folder and in python's libraries folder ...

2016-02-22 16:18:57 -0500 commented question DLL load failed with opencv 3.1 and python 3.5

2016-02-22 02:41:27 -0500 asked a question DLL load failed with opencv 3.1 and python 3.5

Hello,

I installed library OpenCV 3.1 successfully - i used whl file, but i can't import cv2 anyway in my script. I saw this topic: link text ,but installing Microsoft Visual C++ 2015 Redistributable still didn't solve my problem:

ImportError: DLL load failed: The specified module could not be found

When i used pip list module opencv-python is successful installed.

Any suggestions?

PS. I tried different versions of whl files, but it still doesn't help.
