Image recognition and retrieval

A method for image recognition and retrieval, comprising:

• capturing, by a camera of a computing device, a plurality of image frames;
• discarding, by a processor of the computing device, any image frame of the plurality of image frames that does not meet a specified quality threshold;
• after discarding any image frame that does not meet the specified quality threshold, grouping, by the processor, remaining image frames of the plurality of image frames into groups, each group having a specified number of image frames, including a first group of image frames;
• identifying, by the processor, features of the image frames in the first group of image frames;
• generating, by the processor, descriptors describing the features of the image frames in the first group of image frames;
• and
• sending, by the processor, a query to a server to retrieve an image frame stored in the server that matches the first group of image frames, the query comprising the descriptors describing the features of the image frames in the first group of image frames.

A non-transitory computer readable storage medium storing machine-readable instructions that, when executed, cause a processor to:

• capture a plurality of image frames;
• discard any image frame of the plurality of image frames that does not meet a specified quality threshold;
• after discarding any image frame that does not meet the specified quality threshold, group remaining image frames of the plurality of image frames into groups of image frames, including a first group of image frames, wherein each group has a specified number of image frames;
• define features of the image frames in the first group of image frames;
• generate descriptors describing the features of the image frames in the first group of image frames;
• and
• send a query to a server to retrieve an image frame stored in the server that matches the first group of image frames, the query comprising the descriptors describing the features of the image frames in the first group of image frames.
