Rudimentary Recognition of Spoken Words at KTH

Rudimentary Recognition of Spoken Words at KTH

Pattern recognition (EN2202) at KTH Stockholm turned out to be a very good course, concerning lecture, exercises, and the accompanying project work. Together with a fellow student, we created a rudimentary recognizer for spoken words. It is far from production quality, of course. While a good part of the coding has been prepared for the students, the task left enough freedom to play around with hidden markov models in the context of word recognition.

Recognizing Textured Planar Objects with OpenCV

Recognizing Textured Planar Objects with OpenCV

How can we recognize textured objects under the assumption of planarity in images? OpenCV provides extensive support for this task, and helps with local feature extraction, fast approximative matching, and robust model fitting. This article describes a minimalistic detector based solely on OpenCV for all vision subtasks, and also offers pictures, videos, and the source code.

The Viterbi Algorithm and Breadth-First Search

The Viterbi Algorithm and Breadth-First Search

Given a hidden Markov model, we can use the Viterbi algorithm in order to compute the most likely sequence of latent states that produced a certain sequence of observations. Neat: the algorithm is sort of breadth-first search for a maximum in a certain perfect N-ary search tree.

Vetenskap och konst - Fyrverkeriorkestern 2012

Charming. Unbeatable. Inconceivable. So much to the concert at KTH in Stockholm on September 12, which featured a variety of enjoyable pieces and culminated in the overwhelming “Music for the Royal Fireworks” (G. F. Händel).

Wilderness Around the Corner: Tyresta National Park

Tyresta National Park is merely an hour away from Stockholm, and is mostly rocks, wood, water. A special feature is a large area that was flame-cut by a raging wildfire in 1999, now offering a rough and strange landscape.

München-Stockholm by Train includes a Ferry-Ride

München-Stockholm by Train includes a Ferry-Ride

Travelling from Munich to Stockholm by train seems to be a crazy idea at the very first glance. However, coming at a price of 39,- EUR and virtually no baggage limit, I chose to take a 21h train ride on me to Stockholm via Nürnberg, Hamburg and Copenhagen with Deutsche Bahn. While the crowded trains made the journey tougher than expected, I was surprised by getting a ferry-ride for both the Intercity Express and myself.

Olve Maudal and Deep C++

Olve Maudal and Deep C++

Wonder about the depths of C++? Wonder why the code you wrote yesterday no longer works in the morning? Olve Maudal stated on TNG Big Techday 5 in Munich that you ought to look under the hood when you want to understand more about C++. His key statements were: C++ is fast and powerful. Yet, a shark is always lurking in your back, so have an appropriate model in mind. I enjoyed the talk, for more about this, see Olve Maudal’s blog and the freely available slides on the topic.
