nREPL Looper and Computer Vision

This month we have two really interesting talks that are sure to please your auditory and visual senses.

Brock Wilcox will present on nREPL Looper (https://github.com/awwaiid/nrepl-looper): "A guitar-looper-pedal-like­-thing for your REPL!" He'll present his ongoing project, experimenting with recording console commands along with their timing, and then playing them back in a loop. We can use Overtone (sound) events as a good example, simulating a looper-pedal but feeding it commands instead of audio. We'll touch upon a variety of topics as part of the walk through, from beginner to advanced!

Paul Bible will present OpenCV (http://opencv.org/), an open source cross-platform library for computer vision and image processing/analysis. Since image analysis often results from composing multiple filtering and processing steps, Clojure seemed like a natural choice for working with OpenCV. OpenCV is supported in Clojure through java wrappers around dynamic libraries written in c++. See this tutorial (http://docs.opencv.org/doc/tutorials/introduction/clojure_dev_intro/clojure_dev_intro.html) for details. This presentation will demonstrate how to employ Clojure and OpenCV to extract useful information from images, examine certain practical considerations concerning java interoperability, and illustrate how Clojure's style allows for (relatively) headache-free interaction with robust native libraries.
