Waveform generation and recognition system

A processor-implemented method of manipulating an optical code representing an audio waveform present in an audio file, comprising the steps:

• providing a server, a database module, and a non-volatile storage system (NVSS);
• a waveform extraction module running on the server, resident on the non-volatile storage system, receiving the audio file and extracting audio data therefrom;
• an image processing module running on the server, resident on the non-volatile storage system, receiving the audio data from the waveform extraction module and transforming the audio data into a waveform image of a predetermined size, the waveform image having a waveform color and areas in a background of the waveform image having a background color, the waveform image visually representative of the audio waveform;
• a delivery module running on the server, resident on the non-volatile storage system, interacting with a user through a user interface to deliver the waveform image to the user;
• wherein the database module stores a plurality of optical codes and an associated audio waveform and waveform data associated therewith, and further includes:
• an Image Size Normalization (ISN) module running on the server, resident on the NVSS, and configured to receive a code image from the user, the ISN module determining boundaries of the code image, removing whitespace and border artifacts in the code image, cropping the code image, and then resizing the code image to a predetermined normalized image size, the result being a normalized image;
• an Image Pixelating (IP) module running on the server, resident on the NVSS, and configured to divide the normalized image into pixels based on a predetermined grid size, the result being a pixelated image;
• an Image Comparison (IC) module running on the server, resident on the NVSS, and configured to compare the pixelated image with a comparison set of the optical codes stored in the database module, the IC module calculating an overlap percentage with each optical code in the comparison set and the pixelated image, any of the optical codes resulting in an overlap percentage higher than a predetermined threshold being designated as a match;
• a delivery module running on the server, resident on the NVSS, and configured to return to the user, an optical code designated as a match and having the highest overlap percentage, and associated audio waveform and waveform data.

A processor-implemented method for matching a code image with an optical code from a plurality of optical codes each representing an audio waveform associated with waveform data, comprising the steps:

• providing a server, a database module, and a Non-Volatile Storage System (NVSS), the database module storing the plurality of optical codes and associated audio waveform and waveform data associated therewith;
• an Image Size Normalization (ISN) module running on the server and resident on the NVSS, receiving the code image from a user, determining boundaries of the code image, removing whitespace and border artifacts in the code image, cropping the code image, and then resizing the code image to a predetermined normalized image size to produce a normalized image;
• an Image Pixelating (IP) module running on the server and resident on the NVSS, dividing the normalized image into pixels based on a predetermined grid size to produce a pixelated image;
• an Image Comparison (IC) module running on the server and resident on the NVSS, comparing the pixelated image with a comparison set of the optical codes stored in the database module, calculating an overlap percentage between each optical code in the comparison set and the pixelated image, and for any of the optical codes resulting in an overlap percentage higher than a predetermined threshold, designating the optical code as a match;
• a delivery module running on the server and resident on the NVSS returning to the user, an optical code designated as a match and having the highest overlap percentage and associated audio waveform and waveform data.
