Visual Search using Vector Quantization

On Wednesday, 14 January 2015, Ole Eichhorn will discuss Visual Search using Vector Quantization.


The techniques of vector quantization have long been used for data compression, but they can also be used as an innovative way to accomplish pattern recognition. When a dataset is “kernelized” it is transformed into a smaller denser space that enables fast lossy searching. This can be particularly useful as a way to implement image matching for visual search. This talk will describe various ways of “kernelizing” images and methods for storing and retrieving the resulting vectors. It will also describe a visual search engine implementation based on these methods, and touch on related techniques including kernel synonymization and iterative turning. And yes, there will be a demo.
