ColorDetection

I am building an application through which you can automatically get the name of the color by clicking on them.

List of libraries used:

I am learning about OpenCV library and I wanted to do something with the library.

colors.csv - Details of color name and three primary colors Red, Green and Blue and hex number.

In OpenCV library we can show image, brur it, make it black and white image with simple coding.
cv2.imshow("original image",img) - To show the image.
img = cv2.blur(img, ksize = (5, 5)) - To blur the image.
I have drawn a rectangle and to get the color name to draw text on the window using cv2.rectangle and cv2.putText() function.

I am using argparse library to create an argument parser. So I can directly give an image path from the command prompt.
I am using pandas library to read colors.csv file to load the data in the DataFrame.
Calculate distance to get color name - I have the r,g and b values. Now, I have another function which will return us the color name from RGB values. To get the color name, we calculate a distance(d) which tells us how close we are to color and choose the one having minimum distance.
To calculate distance d I used this Formulae - (d) = abs(Red – ithRedColor) + (Green – ithGreenColor) + (Blue – ithBlueColor)
To run this program from command prompt - python color_detection.py -i
We can find the colors of any pictures by giving the image path and name.
