Abstract
Slideshow video file detection. A method includes receiving a search query for video files of a desired type. A portion of a video file is extracted. A frame difference based histogram and an active pixel based histogram are generated for the portion. Further, the frame difference based histogram and an active pixel based histogram are provided to a machine learning tool. An indicator is determined for the portion based on a plurality of parameters. The video file is classified as the desired type based on the indicator. The video file is provided to the user.
Claims18
An article of manufacture comprising:
- a machine-readable medium;
- and
- instructions carried by the medium and operable to cause a programmable processor to perform:
- receiving a search query for video files of a desired type;
- extracting a portion of a video file;
- generating a frame difference based histogram and an active pixel based histogram for the portion;
- providing the frame difference based histogram and the active pixel based histogram to a machine learning tool;
- determining an indicator for the portion based on a plurality of parameters, wherein the plurality of parameters comprise sign vectors, feature vectors, weight vectors and threshold vectors associated with the portion;
- classifying the video file as the desired type based on the indicator;
- and
- providing the video file to the user.

A method for searching video files, the method comprising:
- electronically receiving, in a computer system, a search query for video files of a desired type;
- extracting a portion of a video file;
- generating, electronically in the computer system, a frame difference based histogram and an active pixel based histogram for the portion;
- providing the frame difference based histogram and the active pixel based histogram to a machine learning tool;
- determining an indicator for the portion based on a plurality of parameters, wherein the plurality of parameters comprise sign vectors, feature vectors, weight vectors and threshold vectors associated with the portion;
- classifying the video file as the desired type based on the indicator;
- and
- providing the video file to the user.
A system comprising:
- one or more remotely located electronic devices;
- a communication interface in electronic communication with the one or more remotely located electronic devices for receiving a search query;
- a memory for storing instructions;
- a processor responsive to the instructions to determine video files satisfying the search query and to categorize the video files as slideshow or non-slideshow;
- and
- a storage device for storing the video files.
