Automatic machine recognition of sign language gestures

One or more non-transitory computer readable media storing one or more sequences of instructions which, when executed by one or more processors, cause:

• storing a first training dataset comprising a plurality of digital images of sign language gestures and an alphabetical letter assigned to each digital image of the plurality of digital images;
• training a neural network in a first stage using the plurality of digital images of sign language gestures as input and the alphabetical letter assigned to each digital image as output;
• receiving a particular digital image comprising a particular sign language gesture;
• using the trained neural network, classifying the particular digital image as a particular alphabetical letter;
• causing displaying, on a client computing device, digital data identifying the particular alphabetical letter associated with the particular sign language gesture.

A computer system comprising:

• one or more processors;
• one or more memories storing instructions which, when executed by the one or more processors, cause the one or more processors to perform:
• storing a first training dataset comprising a plurality of digital images of sign language gestures and an alphabetical letter assigned to each digital image of the plurality of digital images;
• training a neural network in a first stage using the plurality of digital images of sign language gestures as input and the alphabetical letter assigned to each digital image as output;
• receiving a particular digital image comprising a particular sign language gesture;
• using the trained neural network, classifying the particular digital image as a particular alphabetical letter;
• causing displaying, on a client computing device, digital data identifying the particular alphabetical letter associated with the particular sign language gesture.
