Write a Python script that takes an input image and output's the name of the dominant color in that image(i.e. red, green, blue).

Expert Solution

import matplotlib.image as img

import matplotlib.pyplot as plt

from scipy.cluster.vq import whiten

from scipy.cluster.vq import kmeans

import pandas as pd

iron_image = img.imread('iron.jpg') //created a random img

r = []

g = []

b = []

for row in iron_image:

for temp_r, temp_g, temp_b, temp in row:

r.append(temp_r)

g.append(temp_g)

b.append(temp_b)

iron_df = pd.DataFrame({'red' : r,

'green' : g,

'blue' : b})

iron_df['scaled_color_red'] = whiten(iron_df['red'])

iron_df['scaled_color_blue'] = whiten(iron_df['blue'])

iron_df['scaled_color_green'] = whiten(iron_df['green'])

cluster_centers, _ = kmeans(iron_df[['scaled_color_red',

'scaled_color_blue',

'scaled_color_green']], 3)

dominant_colors = []

red_std, green_std, blue_std = iron_df[['red',

'green',

'blue']].std()

for cluster_center in cluster_centers:

red_scaled, green_scaled, blue_scaled = cluster_center

dominant_colors.append((

red_scaled * red_std / 255,

green_scaled * green_std / 255,

blue_scaled * blue_std / 255

))

plt.imshow([dominant_colors])

plt.show()

Write a python function image compress() that takes one argument called filename, which is the name of a file that contains a N × N (N-pixel by N-pixel) “grayscale bitmap image”. A “grayscale bitmap image” is an image of the following form where every pixel contains a grayscale color value between 0 − 255 (inclusive). Colour value 0 means that pixel should appear completely black and color value 255means completely white. Any other value in between stands for different shades...

IN PYTHON Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string....

Write a program in python that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid The dates for each season are: Spring: March 20 - June...

Write a Python program that takes as input two numbers, the height, and width of a rectangle. It then prints a rectangle with height lines and width characters in each line. The rectangle should contain information regarding its dimensions and area inside (centered vertically but not horizontally). If any part of the information (including two stars on each end and a space before and after the line) does not fit in the rectangle, then print the complete information after the...

write a python function that takes a number as input argument, and that tries to determine two other integers, root and pwr, such that root**pwr is equal to the integer passed as an argument to the function. Consider that pwr > 1. The function should return the values of root and pwr, as a string in the form root**pwr. For example, when the passed argument is 8, the function should return the string ‘2**3’. When the passed input argument does...
