Capstone Experience

The capstone project is the culmination of one’s experience in college. The foundation, each brick, supports the cap. Everything I was exposed to contributed to the project. GWU CS Senior Design Paper

Background

Owning a 3D printer, is something I’ve always wanted ever since coming to National Maker Faire at NYC in 2014. The ability to generate physical objects from nothing without requiring a complex manufacturing background is what was most appealing to me. You no longer needed to cast objects, or machine parts. You could just melt plastic in the shape of whatever you wanted.

3D Printer, Maker Faire 2015

Residential Building Inspection - Apartment Failure

On February 26th 2018 I finally decided to pull the trigger. Chris’s 3D printer was confiscated from our room for being a safety hazard and being the defiant individual I decided to buy one for myself. (Chris even agreed to provide tech support for it.)

I order the CR-10. The best 3D printer for the price!

During this time, Chris fights GWU and eventually gets the ruling overturned.

For several weeks I’ve been reflecting on my college experience. Did I really change? This is a living post and, is my expression of college. What I gained, what I lost, a collection of an anecdotes, and an attempt to write in an interesting way.

Introduction

Generative Adversarial Networks (GANs) are a relatively new idea in computer science. The idea is that you have a system of two neural networks that are placed in a zero-sum game. One acts as a generator which creates images and the other acts as a discriminator which evaluates the images as real or fake. Essentially you are exploring the space of images that will result in a classification of a neural network and determining the “realness” or “fakeness” of these images. The example that is most often used to explain this idea would be the counterfeiter example.

These images are from Machine Learning is Fun Part 7: Abusing Generative Adversarial Networks to Make 8-bit Pixel Art

You begin by wanting to create a counterfeit bill. The generator creates a bad fake.

Then the discriminator evaluates the fake.

This results in the generator creating better fakes because of...

This post is about hybrid images with Python. I will be following the approach described in the SIGGRAPH 2006 paper.

Approach

The technique described in the paper takes a pair of images, and takes the high frequency of 1st image and the low frequency of the 2nd image.

The low pass filter is taken using the Gaussian filter.

low_pass = gaussian_filter(image_1)

The high pass filter is taken by taking the original image minus the Gaussian filter of the image.

high_pass = image_2 - gaussian_filter(image_2)

The images are then blended together using an average between them.

final_image = (high_pass + low_pass) / 2

The Gaussian filter uses a kernel size that is determined by the sigma. Sigma is calculated through the formula f_c = 1 / (2 * pi * sigma) which is formula for the cut off frequency for the Gaussian filter. This lets me experiment with different cycles/image for each...

This post is about aligning images with Python.

We will be aligning images from Sergei Mikhailovich Prokudin-Gorskii(1863-1944). He took photographs at three exposures using a glass plate filters in order to separate the photograph into three color channels(red, green, and blue). The photographs are online at the library of congress.

First Approach: Brute Force

This gif is an example of what what were are attempting to do in photoshop.

Pseudocode

def align(channel_to_align, image_channel):
    for i in range(-15, 15):
        for j in range(-15, 15):
             Move the image and score it
     return aligned_image

Results

Smaller Images

This example works well on smaller images.

Unaligned Image

Aligned Image

Larger Images

There is very little difference to the unaligned image when using the same algorithm. The reason being, as images become...
