How would you crop multiple ROIs from a np.array? With the coords arranged this way. Rect=([x1,y1,x2,y2],[x1,y1,x2,y2]..

I was able to crop one element. Not each element in the rect np.array. How do I crop all of the spots from both images,

Ok, I was able to use the function absdiff between the two images. I cropped the A0 location in both empty lot and the i

I set up an np.array and was able to print all the elements in python console.

a =np.array([[14,137,80,166],[14,174,80,204],[14,214,80,244],[14,252,80,282],
[14,290,80,320],[14,328,80,358],[14,366,80,396],[14,402,80,432]])
for (x1,y1,x2,y2)in a:
   print(x1,y1,x2,y2)

When I set up the for loop to draw the rectangles I get the last one in the array draw on image.

rect = np.array([[14,137,80,166],[14,174,80,204],[14,214,80,244],[14,252,80,282],
[14,290,80,320],[14,328,80,358],[14,366,80,396],[14,402,80,432]])

for (x1,y1,x2,y2)in rect:
  #Create the basic black image
  mask = np.zeros(blur.shape[:2], dtype="uint8")
  cv2.rectangle(mask,(x1,y1),(x2,y2), (COLOR_WHITE), -1)

Any help greatly appreciated. Thanks.

Thank you for your help! Yes, it probably is silly.

I can not draw the rectangles with the for loop. I set up an np.array and was able to print all the elements in python c

No I have not been able to. I was able to get the differences from the two images. I was hoping to compare each location

I was hoping for the actual locations I created on the mask. The specific locations of A0-A7, B0-B6, and C0-C5. Or some

I want to compare two masked images at specific quadrants(locations) I have managed to bring in a image, turn it to gray

I am able to compare the two images and get bounding boxes. The problem is the bounding boxes are around the exact dif

I am trying to add image, I tried jpg and png, but neither will load in.

I added in upload, but I do not see it, here?
