In bag of visual word model, local key point descriptors which are extracted from the key frame
of the shots are represented by the histograms of visual words.
That is to say, first we calculate the average hue of a visual scene and then select the key frame
closest to the average hue of the visual scene as the representative frame of the scene.
Another approach to retrieve medical videos is a key frame
which is initially extracted and its global features are excerpted, which has to be saved in XML script format in the form of an object to reduce the storage space.
In particular, we illustrate the architecture of this system and explain how we solve the problem regarding scalability and security, and the organization of data and key frame
extraction method are presented in this part.
In our framework, instead of using all frames of a video shot, we perform key frame
extraction at 5 frames per second for saving computational cost.
"That's right, a static ~1500 ms, regardless of key frame
interval," says Vietor.
Here, parts have been proposed which capture a neighborhood of spacetime [7, 8] or a spatial key frame
For each group, video frames are divided into WZ frames and key frames
. H.264 is used for intracoding and decoding of key frame
; meanwhile, WZ frame is encoded by Wyner-Ziv encoder, and the core steps of decoding process are given as follows because of its complexity.
When the scene "getting up in the morning" was finished, a layer was added to the main scene, and the last frame of this layer was turned into a key frame
. Then open the action panel and input the following codes:
For instance, there are sensor nodes (e.g., mouse and keyboard), visual nodes (e.g., shape, material, and textures), motion models (e.g., walk and orbit), animation nodes (e.g., key frame
, rotate, and skeleton), and base nodes (e.g., anti-aliasing, shadow quality, and frame size).

and pump station components in its Northumberland, Pa., plant; and, commercialize the equipment.
