Correct me if I'm wrong but I believe there are 7 elements in the gp_apple list: [apple_copy (index 0), pyrdownimg1(index 1), pyrdownimg2(index 2), pyrdownimg3(index 3), pyrdownimg4 (index 4), pyrdownimg5 (index 5), pyrdownimg6 (index 6)] So when creating the laplacian pyramids, why do you start from the 6th image (index 5) of the gaussian pyramid when there is another smaller pyrDown image at index 6? I'm just trying to understand the point of creating this last image if it is not used? Was this done on purpose for some reason or is it just a mistake?
You should add the Notice when our image has odd shape.(like 255x255). Caused in this case, you can not create laplacian pyramid due to diffrent shapes of 2 images.

I'm late but I'll answer anyway. The two arrays passed to np.hstack have to be in a Tuple. So instead of img1[:, :128], img2[:, 128:] it has to be (img1[:, :128], img2[:, 128:])
Hello Sir! I amgetting error in this code: ">> cols, rows, ch = apple_lap.shape AttributeError: 'list' object has no attribute 'shape' ". can you help me to remove this error? i would be very thankful of you.
he don't know , because entire code and entire sentence which he spoke is copied from opencv documentation. To be honest he also don't know what the code is saying
As it was said earlier by hieu pham, if you pyrUp an image which was of odd shape earlier, you loose some pixels and operation ends with error. For example if you have a (3, 3) image and scale it down, it'll be (1, 1), but if you'll scale it up again it will be of shape (2, 2).
try these, gaussian_extended = cv2.pyrUp(gp[i],dstsize = (gp[i - 1].shape[1], gp[i - 1].shape[0])), I guess the issue is in mismatch size of images, I hope this solves out the error

It's good to know that taking Calculus 3 and Differential Equations had something to do with programming.

can't you just resize your images?
Great concepts. Thank you!
You're the best.
how to download used imaegs in this video?
nice ,simplest tutorial.
Very nice, but I feel like you could just do smoothing filter on the middle between those two halves.

How can i get the images
Hello Sir!
I amgetting error in this code:
">> cols, rows, ch = apple_lap.shape
AttributeError: 'list' object has no attribute 'shape'
".
can you help me to remove this error?
i would be very thankful of you.
convert it into numpy
Sir what if the size of image is not same i mean suppose if size of one image is 693,693 and other is 2136,2136
you will not be able to stack the images
Scale the image by a factor which is common for both
Why I've got error in the
laplacian = cv2.subtract(gp_apple[i-1], gaussian_expanded)
Somebody please help
It is probably because of the size of the image you use, I had the same problem and I changed the image to a 512x512 image
what is the use of that "n" variable?
he don't know , because entire code and entire sentence which he spoke is copied from opencv documentation. To be honest he also don't know what the code is saying
thanks bro.....
Bro u did not mentioned about even rows correction after pyrDown
You did blending but in only one way. what if I want to use a mask for a different type of blending
Error while reconstructing the image. Error in pyrUp function.
Can some one help me out with this.
Try to copy and paste a code piece here. This way probably somebody would be able to help you...

There is also an cv2.Laplacian function.
