This application takes an image, a search and a number of smaller images. It will then use them to create a photo mosaic of the image using google images.

1. Use a Google images scraper in order to download the requested images
2. Get the average colour value for each downloaded image
3. Go through the given image and replace each pixle (or group of pixles) with the closest matching downloaded image (using colour value)
4. Output the resulting image

I mostly referenced this blog post for getting images from google chrome Blog Post

I have created both a Google Image Scraper and a Free Image scraper which uses the pexels image library (each image has a free license) The image scraper takes in the query, number of images wanted, the location they are going to be stored and the final dimensions. I am using an anoconda environment so you can use conda activate photoMoseic in order to install all dependencys

When you want to use the script please use this form python ./GoogleImageScraper.py <QUERY> <NO IMAGES> <PATH> <WIDTHxHEIGHT> python ./FreeImageScraper.py <QUERY> <NO IMAGES> <PATH> <WIDTHxHEIGHT>

e.g. python ./GoogleImageScraper.py 'cat' 5 './images/' '100x100' python ./FreeImageScraper.py 'cat' 5 './images/' '100x100'

The mosaic generator takes the image to be converted, the number of sample images you want to use, the scale of the sample images, the amount you want to shrink the image given and the final location of the image.

The image converter only works on .jpg or .jpeg images

It uses go with a specific library installed for resizing the image (library) use go get github.com/nfnt/resize if you don't have it installed

Run the program via the .exe ./photoMosaic -img <IMAGE> -no <NO SAMPLE IMAGES> -shrink <AMOUNT YOU WANT TO DECREASE BY> -location <LOCATION OF FINAL IMAGE> -images <LOCATION OF SAMPLE IMAGES>

e.g. ./photoMosaic -img '../cat1.jpeg' -no '10' -shrink 10 -location "../image" -images "../images/"

Check that your chrome version and the chrome driver version match, if they don't then download the one that matches your chrome version from here

You might need to make the directory that the images to be scraped will be stored in before linking to it
