Systems and methods for compressing video data using image block matching

A method for image block matching, the method comprising:

• accessing a reference frame of an image in a video;
• separating the reference frame into a plurality of reference blocks of pixels;
• calculating, using a hash function, a hash value for each of the plurality of reference blocks of pixels;
• receiving a current frame of an image in the video;
• separating the current frame into a plurality of current blocks of pixels;
• calculating, using the hash function, a hash value for each of the plurality of current blocks of pixels;
• comparing the hash values associated with the reference frame with the hash values associated with the current frame;
• identifying a hash value in the reference frame that matches a hash value in the current frame;
• and
• storing information indicating that the hash value in the reference frame matches the hash value in the current frame for matching blocks of pixels.

At least one computer-readable storage medium having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the at least one processor to:

• access a reference frame of an image in a video;
• separate the reference frame into a plurality of reference blocks of pixels;
• calculate, using a hash function, a hash value for each of the plurality of reference blocks of pixels;
• receive a current frame of an image in the video;
• separate the current frame into a plurality of current blocks of pixels;
• calculate, using the hash function, a hash value for each of the plurality of current blocks of pixels;
• compare the hash values associated with the reference frame with the hash values associated with the current frame;
• identify a hash value in the reference frame that matches a hash value in the current frame;
• and
• store information indicating that the hash value in the reference frame matches the hash value in the current frame for matching blocks of pixels.
