michvaldes001 / election_2016.php

Last active March 20, 2016 00:34

This script is a crude attempt at analyzing the media's tone for each candidate. See comments in code.

	<?php

	//This script is my crude attempt of trying to quantify the media's tone pertaining to articles about candidates.
	//The script scans the 5 most heavily trafficked news sites that have a search function.
	//It searches and counts key negative and positive adjectives.
	//I excluded Fox News as that would skew my results.
	//Working demo here: http://michvaldes001.ddns.net/index.php?section_id=Apps&app_loaded=yes&app_id=election_2016

	//Display header.
	echo '<h2>Words Used to Describe Candidates (data from Google, Yahoo, CNN, NBC, and NYT news).</h2>';

michvaldes001 / IR_vision_overlay.py

Created October 11, 2015 15:07

This simple bit of code is for a project I'm working on. I intend to to simulate what it would look like if we has an extra cone in our eyes sensitive to near infrared light. This can be done by overlaying the feed of an IR camera over that of a normal camera. In reality we can't really conceive this new color. It would be akin to a colorblind p…

	#must have OpenCV installed
	import cv2

	#gets video feed from both cameras (this is for Linux)
	cam = cv2.VideoCapture(0)
	cam2 = cv2.VideoCapture(1)

	#main loop
	while True:
	#process video feeds
