You know what a certain character looks like, but you forget its name or Unicode code.What are you doing now?Shapecatcher is a new website that can help you find specific unicode characters, just draw their shapes.At present, about 10,000 most important Unicode characters are compared with your sketches and analyzes similarity.

Under the hood, Shapecatcher uses the so -called "shape context" to find similarities between the two shapes.The context is a strong mathematical method describing the concept of similarity between shapes. It is the feature descriptor first proposed by Serge Belongie and Jitendra Malik.

You can find the in -depth explanation of the shape matching framework in my bachelor's dissertation ("About the Security of RECATPCHA").Finally, it is very different from Belongie and Malik's matching framework in 2000, but it is still based on the shape of shape context.

The engine running this website is a rewriting version I developed during the Bachelor's Paper.In order to make things faster, I use CUDA to accelerate some parts of the framework.This is a quite new technology that enables me to use my NVIDIA graphics card for general calculation.The newer card is a very powerful device!

Each query on this website is treated by a graphics card, making the comparison process more than 15 times faster than my CPU.Essentially, CUDA makes it possible to provide high loads on a close -up experience and processing website.
