I would like to filter the image below into green and red. The aim of filtering the image is to be able to count the red and green cells in the image. I am using OpenCV to filter the image but the outcome isn't as expected please see images in Red and green filter. The filtered image seems to include more cells in either color, which will lead to an incorrect count. Is there anything I could do in the code to improve this, please? Many Thanks in advance. import cv2 image = cv2.imread('2020-03-Sequence-p4-Day-0_Position070.png') b = image.copy() # set green and red channels to 0 b[:, :, 1] = 0 b[:, :, 2] = 0 g = image.copy() # set blue and red channels to 0 g[:, :, 0] = 0 g[:, :, 2] = 0 r = image.copy() # set blue and green channels to 0 r[:, :, 0] = 0 r[:, :, 1] = 0 # RGB - Blue cv2.imshow('B-RGB', b) # RGB - Green cv2.imshow('G-RGB', g) # RGB - Red cv2.imshow('R-RGB', r) cv2.waitKey(0) Original image converted_images Continue reading...
