Detailed Description
Embodiments of the multimedia big data hiding system and method of the present invention will be described in detail below with reference to the accompanying drawings.
Video data refers to a sequence of consecutive images, which consists essentially of a set of consecutive images, and for the images themselves, there is no structural information other than the order in which they occur.
A frame is the smallest visual unit that makes up a video, and is a static image. Temporally successive sequences of frames are composited together to form a motion video. The description of the frame can adopt the description method of the image, so the retrieval of the frame can adopt the retrieval method of the similar image.
A shot is made up of a series of frames that depict an event or a continuous motion of a group of cameras. When a video is shot, one lens can be processed by adopting a plurality of camera motion modes according to the needs of a scenario. The lens movement caused by the camera operation mainly includes several forms of panning, zooming, tracking, and the like.
The scene is composed of a series of shots with similar properties, the shots are directed to the same batch of objects in the same environment, but the shooting angle and the shooting method of each shot are different. Scenes have certain semantics and from a narrative point of view, scenes are taken at the same location and thus have the same subject matter.
At present, when a mobile phone is used for video playing, a video authorized user or a video unauthorized user cannot be subjected to differential user management, for example, for video content with an excessively high user click rate, the video authorized user or the video unauthorized user can search on an interface and can enter a playing interface, so that the experience of the video authorized user is poor.

In addition, the parameter authentication apparatus may be implemented using a GPU chip. The GPU is different from a DSP (Digital Signal Processing) architecture in several major aspects. All its calculations use floating point arithmetic and there is no bit or integer arithmetic instruction at this time. Furthermore, since the GPU is designed specifically for image processing, the storage system is actually a two-dimensional, segmented storage space, including a segment number (from which the image is read) and a two-dimensional address (X, Y coordinates in the image). Furthermore, there is no indirect write instruction. The output write address is determined by the raster processor and cannot be changed by the program. This is a significant challenge for algorithms that are naturally distributed among the memories. Finally, no communication is allowed between the processes of different shards. In effect, the fragment processor is a SIMD data parallel execution unit, executing code independently in all fragments.
While simple in concept, new users are confused when using GPU computing because GPUs require proprietary graphical knowledge, in which case some software tools may provide help, two high-level shading languages CG and H L S L enable users to write C-like code and then compile into a sharps assembler language Brook is a high-level language designed specifically for GPU computing and not requiring graphical knowledge, so it is a good starting point for workers who develop for the first time using GPUs, Brook is an extension of the C language, integrating simple data parallel programming constructs that can be directly mapped to.
Finally, it should be noted that each functional device in the embodiments of the present invention may be integrated into one processing device, or each device may exist alone physically, or two or more devices may be integrated into one device.
The functions, if implemented in the form of software-enabled devices and sold or used as a stand-alone product, may be stored in a computer-readable storage medium. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk or an optical disk, and other various media capable of storing program codes.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
