Hello I'm Peter from Leipzig and I'm a softwaredeveloper.

I'm interested in 3D Computergraphics, Image Processing and Algorithms. With my actual career I was able to appropriate a strong knowledge about these topics. Further I have experiences with Microservices, Restful API`s and Message Brokers.

EDUCATION

HTW Berlin

Internationale Medieninformatik, Master of Science

After one year break, biking through Europe, I continued my study. By changing the university of applied science I was looking for more challenges. In this 2.5 years I specialised on Computer Vision/Image Processing. I learned a lot about Structure From Motion, (Visual) Information Retrieval, Image Features and Computer Vision. I also selected some lessons in Games where I figured out how less time it is to compute one frame. My master thesis was in coorperation with "Gesellschaft zur Förderung angewandter Informatik e.V." and was about: "Segmentation and Feature Detection on human 3D-Bodyscandata".

10/2012 - 03/2015

HTW Dresden

Medieninformatik, Bachelor of Science

I started this study without any programming knowledge. From the first day of my Bachelor I figured out that Softwaredevelopment and Computergraphics have some special fascination for me. So I concentrated me to learn in this topics the most and get practice by programming a lot. My bachelor thesis was about: "Managed Multimedia with XNA and WPF".

PORTFOLIO

Speeded Up Robust Features

I implemented the Speeded Up Robust Features (SURF) Algorithm after the Paper. First part was the Feature Detection where are approximated Filter are used. The description of the Feature was computed by the Gradients. Later I used the SURF Feature for Visual Information Retrieval and examined if it is possible to a neuronal network for dimension reduction of SURF feature vectors.

Language: Java

Structure from Motion

In a student project we build an app for android for the reconstruction of real object by structure from motion. I was responsible for the image processing and algorithmic part. The app didn't work in any case but I learned a lot about stereoscopic mathemathics.

Where: HTW Berlin
Language: Java

Raytracer

I implemented many intersection algorithms for a basic Raytracer. After finding the intersection the next task was to programm different lightning models (phong- and blinn-shading). With textures and bump-mapping the small raytracer was complete.

Where: HTW Dresden
Language: C#

3D Computer Graphics

At my Bachelor time I implemented many algorithms in Computer Graphics. I understand what projection, rasterization, triangulation, splines, volume modell, subdivision and other basic computer graphics things are. The employment at the "Gesellschaft zur Förderung angewandter Informatik e.V." made my knowledge in the direction of 3D really strong. There I implemented several plugins for Final Surface, an application for analyse, editing and creating of 3D content.

Language: C#, C++

Image Processing

At the HTW Berlin my main focus was to Visual Computing. So I learned and implemented a lot of image processing algorithms. In direction Computer Vision I have now practical experience by programming hough-transformation, filters, correlation coefficients and my own project was on symmetry detection on house facades. I also know now, how to vectorize binary images by the potrace algorithm.

Where: HTW Berlin
Language: Java

Visual Information Retrival

A really interesting topic with challenging tasks. I learned and programmed the basics for Visual Information Retriaval (Thumbnails, Median-Cut Algorithm). In the lesson project I implemented a version of a Color-Based Histogram as a Image descriptor. I also used my implementation of SURF for finding similar Images in an Database. A topic where I definitely want learn more.

Language: Java

2D Physic Engine

After my master study it was time to implement my own project. Actually I'm writing a 2D physic engine. The Basic knowledge about the Game Loop I know from my study. The rest is collision detection (Separate Axis Theorem), impulse calculation and other interesting formulas.

Where: At my desk
Language: Java

Real Time Interactive System

In the module at the HTW Berlin we developed a System with keyboard input, sound output and graphic output. All of that we had to handle in a game loop. Wasn't that easy after we started to add a particle system which made the application really slow. We also plugged some sprites to the Box2D physics engine. I really like python!
