Hello this is in python! Please write this code of merging two images together. Please read the rules. The inputs to your function are: (i) image left: grace\_1.png (size: 350 Rows X 340 Cols), (ii) image right: grace\_2.png (size: 350 Rows X 340 Cols), (iii) image column (c) at which the images should be merged. image_op/operations.py: Edit the function merge Define a new image as follows: the first c columns (default value = 155) should be equal to the first c columns of the left image (grace_1.png). The remaining columns should be equal to the columns greater than c from the right image (grace_2.png). def merge(self, image_left, image_right, column):"""Merge image_left and image_right at column (column)image_left: the input image 1image_right: the input image 2column: column at which the images should be mergedreturns the merged image at column"""# add your code here # Please do not change the structurereturn image_left # Currently the original image is returned, please…
The grayscale2 function is already written, you just need to write inside it how to convert an image to grayscale using the crude average of RGB: from images import Image def grayscale1(image): """Converts an image to grayscale using the psychologically accurate transformations.""" for y inrange(image.getHeight()): for x inrange(image.getWidth()): (r, g, b) = image.getPixel(x, y) r = int(r * 0.299) g = int(g * 0.587) b = int(b * 0.114) lum = r + g + b image.setPixel(x, y, (lum, lum, lum)) def grayscale2(image): """Converts an image to grayscale using the crude average of the r, g, and b""" pass def main(): filename = input("Enter the image file name: ") image = Image(filename) grayscale2(image) image.draw() if __name__ == "__main__": main()
USING PYTHON: Create a function that takes a filename("string") of a PGM image file as input and loads in the image in the file, and returns it as an image matrix. Rules: Cannot make any input calls in the main body, use basic python (nothing like .shape or .width) I have attached an example of what the function should do, as well as what the PGM image file looks like.
Please use Python language must be done without using the built-in function. (please with the help of loops) it could be any images. (image processing libraries should only be used to read and print images.) Define on the output of following kernels. Implement these filters to two different images you prefer with Python. Provide the outputs.
I'm trying to make this program that will output the values of my function display under the subclass items (Circle, Square, Cube) into a file, but when I have a function (display) with multiple lines of return/ print statements the file will show "None" in place of any of the data. class Shape: def __init__(self): self.__color = "red" def set_color(self, color): self.__color = color def get_color(self): return self.__color def find_area(self): pass def find_volume(self): pass def display(self): print(self.__color) class Circle(Shape): def __init__(self): super().__init__() self.__radius = 1 def set_radius(self, radius): self.__radius = radius def get_radius(self): return self.__radius def find_area(self): return 3.14 * self.__radius ** 2 def display(self): print("Type: Circle") super().display() print("Area:",…
Define a function named posterize. This function expects an image and a tuple of RGB values as arguments. The function modifies the image like the blackAndWhite function developed in Chapter 7 and shown below, but it uses passed in RGB values instead of black.
Find and replace problem You will implement a replica of find and replace option available in the word document !!! (attached below) Input: An initialized one dimensional character array of size 100 and the strings that would be found and replaced with. Output: The input character array after being replaced by the requested string. Sample Input: a:"A quick brown fox jumps over the lazy dog." Find: "fox", Replace: "tiger" Sample Output: "A quick brown tiger jumps over the lazy dog." Define a separate function that accepts three arguments as input string, find and replace string and implement the find and replace inside that function. You can use the strcmp() function for the string comparison along with other necessary libraries. You need to call that function from the main function and print the result in the main function. (e.g. use the pointer concept)
[For Programming Language Paradigms] Write code in DrRacket (file should be .rkt). Use the #lang scheme directive at the beginning of your Racket source file. Include screenshots of all of the source code as well as screenshots of the output to prove that it works properly. (last-element ‘(a (b c) (()) (d))) should return ’((d)) so make sure that example is visible in the output screenshot
STEP 1: Begin work within your Jupyter Notebook by importing the following modules: import numpy as np import pandas as pd from matplotlib import pyplot as plt import re Jupyter Notebooks Q1. Within your Jupyter Notebook, write the code for a Python function called def parseWeatherByYear(year) : This function will parse an html page containing weather for an entire year of data for the city of Toronto. The html pages containing weather data can be downloaded from: https://www.extremeweatherwatch.com/cities/toronto/year-2023 The file to parse for this lab however can be downloaded here: https://matrix.senecacollege.ca/~danny.abesdris/prg550.232/labs/lab6/torontoWeather.2023.html The html file itself contains markers as where to begin parsing the data to extract. The 3 pieces of data that must be extracted consist of the high and low temperatures (in degrees Celsius) as well as the amount of precipitation (in cm) for every day so far in the current year (2023).

Greetings I am trying to loop code over several FITS files to overlay several plots. At the moment I am only getting one graph (see pic) Ideally I would like to loop through several FITS that are in a folder on my Desktop. this is what I have so far. Im thinking that I will need to define a function to be able to do this. import numpy as npimport matplotlib.pyplot as pltfrom astropy.io import fitsfrom astropy.wcs import WCSfrom mpl_interactions import ioff, panhandler, zoom_factory%matplotlib widget spec_list = ['~/Desktop/r.HARPN.2018-01-18T14:25:36.145_CCF_A.fits', '~/Desktop/r.HARPN.2018-01-18T14:20:10.645_CCF_A.fits', '~/Desktop/r.HARPN.2018-01-18T14:31:00.875_CCF_A.fits', '~/Desktop/r.HARPN.2018-01-18T14:36:26.373_CCF_A.fits'] for i in spec_list: hdul = fits.open(i) data = hdul[1].data h1 = hdul[1].header flux = data[1] w = WCS(h1, naxis=1, relax=False, fix=False) lam = w.wcs_pix2world(np.arange(len(flux)), 0)[0]…
Javascript I am stuck on a piece of code and I can quite figure out how to finish one part of this function. This is what I have so far: const usersTestArray = [ {id: "1", name: "Joe Graham", option: "option1"}, {id: "2", name: "Kyle Howell", option: "option2"}, {id:"3", name: "Lucy Bauch", option: "option3"}, {id: "4", name: "Sammie Lebsack", option: "option4"} ] const createSelectOptions = (usersTestArray) => { if(!usersTestArray){ return undefined } return userTestArray.map((x) => x.option) } Most of this is correct, however, in the function above, I need to add a create an option element for each user in the array with document.createElement(). I then need to assign the user.id to option.value and the user.name to option.textContent. then it is supposed to return an array of option elements.
for my python class I am to write a program to modify immages. the image format being used is a PPM. the PPM image format is encoded in human readable plan text. PPM image has two parts (1. header and 2. body PPM BodyBelow the header is the body of the PPM file. Each pixel has a red,green, and blue value as indicated by an integer number between 0 and255. For example, the pixel with a RGB value of (255, 0, 0) representsthe color Red.Example PPM ImageDownload the PPM image of the NY sky line. You can open theimage with a PPM image reader software such as Ifranview. The imagefile can also be opened as plain text in a text editor, which allows us toedit the image.Tasks:Write a program to modify a PPM image in the following ways:1. Negate the colors in the image2. Apply a high contrast to the image3. Apply a gray scale to the image4. Remove a primary color (red, green, blue) from the imageYour program should follow the steps below:1. Prompt the user to enter the input PPM file name, the…
