2D Discrete Fourier Transform (Python)

2015-01-03T03:39:34-08:00

Python recipe 578997 by FB36 (image, images, image_processing, math, mathematics, signal_processing).

2D Discrete Fourier Transform (DFT) and its inverse.

Calculates 2D DFT of an image and recreates the image using inverse 2D DFT.

Computation is slow so only suitable for thumbnail size images.

Draw Text To Image (Python)

2015-07-13T18:04:30-07:00

Python recipe 579013 by FB36 (image, images, pil). Revision 2.

PIL does not allow resizing default bitmap font. This code resizes it by itself.

The disadvantage is slow speed but the advantage is it becomes possible to set color of each pixel of text foreground and background.

As an example I set foreground to reverse colors and background to grayscale.

Mandelbrot Fractal image output to ppm file (Python)

2015-01-17T19:21:47-08:00

Python recipe 579006 by FB36 (fractal, image, images, math, mathematics).

It creates image output without using any external library.

PPM image files can be viewed and converted to other image file formats using many applications, GIMP or IrfanView for example.

CGI Image Viewer (Python)

2012-07-02T22:52:32-07:00

Python recipe 578186 by Stephen Chappell (archive, cgi, images, old).

If you have ever started a program and never finished it, then you may recognize the code below for what it is: an experiment begun but not completed, meant to allow viewing pictures on a server. It is included here as an exercise for the reader to complete and is committed for archival to be run under Python 2.5 or later versions.

mouse click to crop many large photos quickly [Python, PIL, pygame] (Python)

2012-01-09T03:18:01-08:00

Python recipe 578005 by Elliot Hallmark (crop, images, jpeg, mouse, pil, png).

Waste no mouse clicks making multiple crops on many image files. Through pygame interface with pan, zoom and next/previous image. Saves files at new resolution and serialized names in a seperate folder. the mainloop() and helper functions are easy to reuse, but I include a cruddy text based interface if needed. if not, comment out most of __main__().

Requires PIL (python imaging library) and pygame.

Comparing two images (Python)

2011-04-03T11:13:24-07:00

Python recipe 577630 by Charlie Clark (compare, images).

Compare two images using the root mean squared analysis. A result close to 0 means a good match.

Bitmap Maker (Python)

2011-04-21T13:08:46-07:00

Python recipe 577674 by Stephen Chappell (experiment, generator, images, proof_of_concept, test).

A friend and I were discussing the possibility of creating every possible image that is 800x600x24 (800 pixels wide by 600 pixels tall and using 24-bit color). This recipe is a proof-of-concept program showing what is possible with just a 2x2 image using 15 different colors (yielding a total of 50,625 images when run). In terms of the original thought experiment, a total of 16777216 ** 480000 images should be possible given the 800x600x24 specifications (or 1 << 11520000 in binary). In base 10 that is 10 ** 3467865.55 and shows that there are an enormous number of possible states that a 800x600 canvas can take.

If you have any comments or wish to down-vote this recipe, please provide your insight as to what could be improved upon and how you would go about fixing any problems that you might find.

Download all lolcat images from iCanHasCheezburger.com (Python)

2011-03-10T08:49:14-08:00

Python recipe 577603 by Rahul Anand (download, images, lolcat, python, web).

Running this python script will download all lolcat images from icanhascheezburger.com to the current folder. Download will start from the oldest image. Images are collected into subfolders lolcat0, lolcat1 etc, each containing 300 images. The script can be stopped and resumed at anytime. Make sure to create files lolconfig.txt and log.txt in the same folder before running the script. lolconfig.txt must have a string as follows in the beginning: 1496/1496/0. log.txt is an empty file in the beginning

Mass image resizing (with progress bar and details in console) (Python)

2010-04-13T07:06:09-07:00

Python recipe 577189 by Rahul Anand (images, image_processing, python). Revision 2.

This script uses the Python Imaging libraries to resize images in a folder and its sub-folders iteratively. The details like the directory hierarchy, current progress etc are displayed dynamically. We can optionally specify more image formats, required size etc.(See command-line argument --help). This is meant for processing large collections of images, which justifies the display of many details.
