"You know what some #character looks like, but you've forgotten its name or its #Unicode code point. Now what do you do? #Shapecatcher is a new website, that helps you to find specific Unicode characters, just by #sketching their shape. Currently about 10000 of the most important Unicode characters are compared to your sketch and are analysed for similarities.
Under the hood, Shapecatcher uses so called " #shape contexts" to find similarities between two shapes. Shape contexts, a robust mathematical way of describing the concept of similarity between shapes, is a feature descriptor first proposed by #SergeBelongie and #JitendraMalik."
