Abstract
Methods and apparatus are disclosed to index digital frames. An example method includes identifying channel types associated with a plurality of image frames, splitting each one of the plurality of image frames into a respective color channel based on the identified channel types, applying a local binary pattern to each of the respective color channels to generate a respective pattern number, generating a spatial representation of each respective pattern number to determine transition probabilities for each channel type, and identifying a degree of similarity between the plurality of image frames based on the transition probabilities.
Claims20
A method to identify a degree of similarity between image frames, comprising:
- identifying channel types associated with image frames;
- splitting respective ones of the image frames into respective color channels based on the identified channel types;
- applying a local binary pattern to pixel neighborhoods of the respective color channels to generate respective pattern numbers;
- generating spatial representations of respective ones of the pattern numbers to determine transition probabilities for the channel types when transitioning between the pixel neighborhoods;
- and
- recombining the color channels to identify a degree of similarity between the image frames based on the transition probabilities.
A tangible machine readable storage device or storage disk comprising instructions that, when executed, cause a machine to at least:
- identify channel types associated with image frames;
- split ones of the image frames into respective color channels based on the identified channel types;
- apply a local binary pattern to pixel neighborhoods of the respective color channels to generate respective pattern numbers;
- generate spatial representations of respective ones of the pattern numbers to determine transition probabilities for the channel types when transitioning between the pixel neighborhoods;
- and
- recombine the color channels to identify a degree of similarity between the plurality of image frames based on the transition probabilities.
An apparatus comprising:
- a memory comprising machine readable instructions;
- and
