Incomplete image is displayed

Hey Dhaivat,

Thanks for reaching out.

Could you please copy-paste the code you are running? Are you using PyCharm?

Kind regards,

Hello Hristina,

I am using VS Code. Below is the code:

import numpy as np
import cv2
img = cv2.imread('capstone_coins.png',cv2.IMREAD_GRAYSCALE)
org_img = cv2.imread('capstone_coins.png',1)
img = cv2.GaussianBlur(img,(5,5),0)
cv2.imshow('Detected Coins',org_img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Hey again Dhaivat,

Unfortunately, I'm not certain why this issue occurs. Please, experiment with the following:

- try to increase your display resolution

- alternatively, modify your code by adding the following line of code before executing imshow:

cv2.resize

- or maybe add the following, again before executing imshow:

cv2.WINDOW_NORMAL

Let me know if any of the following solved the problem.

Kind regards,

Sorry, but none of them works. Stuck!!

Hello Hristina,

Just wanted to let you know that I resolved the issue as follows:

I had to truncate the image using any image-editing tool (cropping, basically). This changed the image size and the entire image could be displayed. So, I had to fiddle a bit with the argument values in cv2.HoughCircles function (with param1, param2, minDistance, etc). It detected all the circles finally. It also detected an additional circle, which I could remove by adjusting the GaussianBlur kernel size to (7,7).  The only aspects which I made different from Giles's solution are as below (rest of the code is the same):

img = cv2.GaussianBlur(img,(7,7),0)

circles = cv2.HoughCircles(img,cv2.HOUGH_GRADIENT,1,150,param1=33,param2=31,minRadius=40,maxRadius=130)

So, basically, this looks like a trial-and-error solution and there is no one way in which a program working on 1 computer would definitely work on another computer. In such a scenario, would it not be an issue if we make a program for a customer and then it doesn't work on their computer? So, though I have been able to resolve my issue by trying out certain values, I am really concerned about the query and how can we resolve this. Can you please elaborate?
