Abstract
Examples of the present disclosure relate to performing subject oriented compression. A content file, such as a video file, may be received. One or more subjects of interest may be identified in the content file. The identified subjects of interest may be associated with a quantization value that is less than a quantization value associated with the rest of the content. When the content is compressed/encoded, the subjects of interest are compressed/encoded using their associated quantization value while the rest of the content is compressed/encoded using a larger quantization value.
Claims20
A method of performing subject-oriented compression, the method comprising:
- identifying a subject of interest in an image;
- compressing the subject of interest using a first quantization value;
- and
- compressing the remainder of the image using a second quantization value, wherein the second quantization value is greater than the first quantization value.
A system comprising:
- at least one processor;
- and
- memory encoding computer executable instructions that, when executed by the at least one processor, perform a method comprising:
- receiving a video;
- creating at least one metadata file;
- identifying at least one subject of interest;
- associating a quantization value with the at least one subject of interest;
- tracking the at least one subject of interest;
- and
- saving metadata generated during tracking to the at least one metadata file.
A computer storage medium encoding computer executable instructions that, when executed by at least one processor, perform a method comprising:
- receiving a video;
- creating at least one metadata file;
- identifying at least one subject of interest;
- associating a quantization value with the at least one subject of interest;
- tracking the at least one subject of interest;
- saving metadata generated during tracking to the at least one metadata file;
- and
- performing subject oriented compression on the video using the at least one metadata file.
