Image add¶
This is a method used to perform pixelwise addition between images. The numpy addition function '+' is used. This is a modulo operation rather than the cv2.add fxn which is a saturation operation.
image_add(img1, img2, device, debug=None)
returns device, image of the sum of both images
- Parameters:
- img1 - image to add
- img2 - image to add
- device - Counter for image processing steps
- debug - None, "print", or "plot". Print = save to file, Plot = print to screen. Default = None
- Context:
- Used to combine/stack the pixelwise intensity found in two images
- Example use:
Image 1 to be added
Image 2 to be added
import plantcv as pcv
# Add two images together
# Results to combine/stack the pixelwise intensity found in two images
device, sum_img = pcv.image_add(img1, img2 device, debug="print")
Sum of images 1 and 2
