How to count pixel in Image? Tutorial

How to count pixel in image using Python and Opencv? First let's read our image:

image=cv2.imread('flower.jpg')

Convert the image to rgb:

image=cv2.cvtColor(image,cv2.COLOR_BGR2RGB)

Create a numpy array:

array = np.array(image)

Arrange all pixels into a tall column of 3 RGB values and find unique rows:

colours, counts = np.unique(array.reshape(-1, 3), axis=0, return_counts=1)

Prints:

print(colours)
print(counts)

All Code:

import numpy as np
import cv2


image=cv2.imread('flower.jpg')
cv2.imshow("Image",image)
image=cv2.cvtColor(image,cv2.COLOR_BGR2RGB)

array = np.array(image)

colours, counts = np.unique(array.reshape(-1, 3), axis=0, return_counts=1)

print(colours)
print(counts)
cv2.waitKey(0)

OpenCV Add Border to Image in Python

How to add border to image in python? To create a frame around the image, the function cv2.copyMakeBorder () is used. This function takes the following arguments: src - login image top, bottom, left, right - edge width in number of pixels in corresponding directions borderType - defines what type of border to add. There may be the following types cv2.BORDER_CONSTANT cv2.BORDER_REFLECT - cv2.BORDER_REFLECT_101 cv2.BORDER_REPLICATE cv2.BORDER_WRAP value - Color of border if border type is cv2.BORDER_CONSTANT import cv2 import numpy as np from matplotlib import pyplot as plt BLUE = [ 255 , 0 , 0 ] img1 = cv2.imread( 'flower.jpg' ) replicate = cv2.copyMakeBorder(img1 , 10 , 10 , 10 , 10 , cv2.BORDER_REPLICATE) reflect = cv2.copyMakeBorder(img1 , 10 , 10 , 10 , 10 , cv2.BORDER_REFLECT) reflect101 = cv2.copyMakeBorder(img1 , 10 , 10 , 10 , 10 , cv2.BORDER_REFLECT_101) wrap = cv2.copyMakeBorder(img1 , 10 , 10 , 10 , 10 , cv2.BORDER_WRAP) constant= cv2.copyMakeBorder(img1 ...
