A little knowledge about cameras/optics will be useful to understand the post; I tried to include supplementary links where helpful.
This past year, I worked on a project for a Computer Vision class to construct depth maps from a scene using a stationary camera by changing aperture and focus only, via a Monte Carlo method. This a writeup of my work; comment below to discuss/ask questions!
Images borrowed from a paper by Jacobs et al. The goal of this project was to take a scene (shown left) and construct a depth map (shown right). For this project, I was interested in creating relative depth maps (where a pixel is darker/lighter if it is closer to the camera than another pixel) as opposed to an absolute depth map (where the intensity of a pixel is proportional to its distance from the camera).
Venmo is a payment system designed for mobile devices that makes it easy to pay or transfer money over to friends (venmo.com).
Venmo’s currently having a promotion on moneytree.venmo.com where they’re giving 1 million dollars in total to new Venmo users who play their game. The game is pretty self-explanatory: you have 10 seconds to click on leaves falling from the “money tree”, each green leaf clicked gets you 10 cents and each blue leaf clicked gets you 20 cents.
After you’re done, you can share the game with friends to continue playing or collect your winnings (if you’re a new visitor) by giving Venmo your phone number and installing the Venmo app:
Learning to program is difficult: 30-60% of students in university introductory programming courses fail. This is associated with a belief that only students with a natural “aptitude” or talent for programming are able to truly succeed in learning to program, while students without this aptitude are doomed for failure or at best mediocrity in programming. Although studies have shown that this programming achievement gap based on natural talent does exist in introductory courses, recent work has pointed towards pair programming as a possible solution for helping bridge this gap.
Just a disclaimer before I start:
I am not in any way condemning the RIAA (Recording Industry Association of America) for what they did or claiming that in some way they “wronged” me; they had the right to send me a cease-and-desist and I immediately complied. I’m simply telling my story about how my website/apps with 15 million hits a month got shut down, which others may find interesting.
