Compression algorithms for speech, audio, still images, and video are quite complicated and, more importantly, nearly always lossy. Thus, samples often change dramatically once they’re decompressed.

Recent progress in camera systems, image analysis, and machine learning have made optical-based gesture recognition a more attractive option in most contexts. However, current methods are hindered by ...

“To me, an algorithm is any piece of automated code that accepts some number of variables and data, [then] uses those variables and data to make decisions. But that’s the boring computer science ...
