Method for output creation based on video content characteristics
The present application is directed to new methods for automatically determining several characteristics of frames in a video sequence and automatically recommending or preparing image output products based on those frame characteristics. In some embodiments, motion characteristics of particular image frames are calculated, and those motion characteristics are automatically used to prepare or recommend image output products suitable for the motion characteristics of the frames. In other embodiments, facial, audio, and overall image quality are assessed and used to automatically recommend or prepare image output products. In still other embodiments, image frames in a video sequence are analyzed for various user-specified characteristics, which characteristics are then used to automatically recommend or prepare image output products.
1. A method of selecting a group of frames from a video sequence, comprising:
accessing a video sequence from a collection of media assets stored in a memory;
using a data processor to automatically analyze the video sequence to compute motion characteristics of content of the video frames;
classifying the video frames according to the computed motion characteristics of the content of the video frames, wherein classifying the video frames comprises classifying each video frame as one of a set of detectable motion classes, and wherein the set of detectable motion classes comprises a high motion class, a moderate motion class, and low motion class;
storing the classified video frames for each respective detectable motion class of the set of detectable motion classes in a memory;
selecting a frame from the classified video frames comprising determining an amount of motion blur by comparing the computed motion characteristics with a frame rate at which the video frames were recorded, yielding a selected frame;
recommending to a user that an image of a plurality of image types be prepared from the selected frame;
further recommending to the user a size of the recommended image based upon the recommended image type; and
previewing by the user of the recommended image before a final image is prepared for further processing.
2. The method of claim 1 , wherein if the motion class is high motion, the video frames will be used to create a video action image or video drama image.
3. The method of claim 1 , wherein if the motion class is low motion or inactive, the video frames will be used to create a high resolution image.
4. The method of claim 1 , wherein if the motion class is moderate motion, the video frames will be used to create a panoramic image.
5. The method of claim 1 , wherein further processing of the recommended image comprises printing of the recommended image.
6. The method of claim 1 , wherein the plurality of motion classes comprises a high motion class, an intermediate motion class, and a low motion or inactive motion class.
