Detailed Description
Embodiments of the adaptive short video content enhancement system of the present invention will be described in detail below.
Signal processing is employed in a number of important fields of application with great osmotic power. The engineering and construction department is used for simulating the earthquake resistance and the earthquake resistance of a large-scale building structure; machine manufacturing to analyze models of mechanical structure vibrations to improve vibration performance and structure; in the aircraft industry for checking the transmission characteristics and wear of engines; the space remote sensing is used for classifying ground vegetation conditions and distributing meteorological cloud layers, and is used for B ultrasonic and X-ray pictures and analyzing and diagnosing physiological electric signals in the medical field; in the fields of telecommunications and electronics, digital signal processing is the most straightforward application.
In the field of telecommunications, the most typical uses of digital signal processing are:
(1) speech coding and compression. The digitized voice occupies a wide frequency band, and needs to be compressed for narrow-band transmission and efficient storage. Typically a 64kbit/s code rate is required for a speech. Medium-speed coding requires that the code rate is compressed to 32kbit/s, 16kbit/s or even 8kbit/s, and still good voice quality is maintained. With digital signal processing techniques, many adaptive coding schemes have been proposed to meet the specifications recommended by the international telegraph telephone counseling committee. The code rate required by low-speed coding is reduced to 4.8kbit/s and 2.4kbit/s to 800bit/s, and the method is realized by a good algorithm and hardware.
(2) And (5) image coding and compression. The amount of data after digital encoding is very large, whether it is still images or moving images, or even television images. The high-quality transmission of the materials is generally carried out by compressing the materials to 1/10-1/100. Various coding methods, so-called wavelet transform methods and fractal signal analysis methods, all provide feasible schemes for high compression ratio television coding.
(3) And designing a shunt filter bank and a combiner filter bank. The core of the technical realization of the time division/frequency division multiplexing equipment is a shunt filter bank. The design and implementation of the shunt filter bank completely depend on the digital filter bank in the digital signal processing, and the digital filter bank has uniform, stable and reliable performance and high cost performance.
(4) Adaptive equalization and echo cancellation. Equalization and echo cancellation are essential in long-distance data communication. The adoption of analog devices has failed to achieve equalization suitable for various channel requirements, and the performance of the analog devices can only be guaranteed by a digital method.
The application of signal processing techniques has evolved to a wide extent not inferior to electronic computer applications. With the continuous discovery of algorithms and the continuous generation of devices, signal processing becomes a basic subject that all telecom engineers need to be familiar with.
Currently, in the production of short video, the same image processing strategy is performed for each frame picture without considering the difference in the content of the different pictures. For example, rich-content pictures require clearer target boundaries, while poor-content pictures do not require the expenditure of significant enhancement processing to obtain clear target boundaries. The short video with poor manufacturing effect can not reach the due powder absorption effect naturally after being uploaded.
In order to overcome the defects, the invention builds a self-adaptive short video content enhancement system, and can effectively solve the corresponding technical problem.
An adaptive short video content enhancement system shown according to an embodiment of the present invention includes:
the signal video recording equipment is used for executing video recording action of a short video on a current video recording scene so as to obtain a section of short video from video recording starting time to video recording ending time, wherein the short video comprises each field video image;
the data updating device is connected with the short video big data server through a network and is used for receiving each content enhanced image corresponding to each field video image respectively and sending each content enhanced image as an updated short video to the short video big data server;
the histogram processing equipment is connected with the signal recording equipment and is used for executing histogram equalization processing on each field video image to obtain a corresponding equalization processing image;
the signal correction device is connected with the histogram processing device and used for receiving the equalization processing image and executing white balance processing on the equalization processing image to obtain a corresponding signal correction image;
an affine transformation device connected to the signal correction device for performing affine transformation processing on the received signal correction image to obtain and output a corresponding affine transformation image;
the object detection device is connected with the affine transformation device and used for acquiring the affine transformation image, detecting the number of imaging objects in the affine transformation image and determining the corresponding edge enhancement times based on the number of the imaging objects;
the dynamic enhancement device is respectively connected with the data updating device and the target detection device and is used for executing multiple times of edge enhancement processing consistent with the edge enhancement times on the affine transformation image so as to obtain a corresponding content enhanced image;
wherein determining the corresponding edge enhancement times based on the number of imaged targets comprises: the determined edge enhancement times are proportional to the number of imaging targets;
the dynamic enhancement equipment, the data updating equipment and the target detection equipment are all arranged at the rear end of the signal video recording equipment, and the front end of the signal video recording equipment is a video recording opening.
Next, the detailed structure of the adaptive short video content enhancement system of the present invention will be further described.
The adaptive short video content enhancement system may further include:
and the touch screen is used for receiving input information of the user according to the operation of the user.
The adaptive short video content enhancement system may further include:
and the video communication equipment is used for wirelessly sending the field image obtained by image acquisition of the environment where the target detection equipment is located.
In the adaptive short video content enhancement system:
the video communication apparatus includes a compression encoding device for performing MPEG-4 standard compression on a live image to obtain a compressed image.
In the adaptive short video content enhancement system:
the video communication equipment comprises a multi-index coding device which is connected with the compression coding device and is used for carrying out multi-index coding on the compressed image to obtain channel coding data.
In the adaptive short video content enhancement system:
the video communication device comprises a wireless communication interface connected with the multi-index coding device and used for wirelessly transmitting channel coding data.
In the adaptive short video content enhancement system:
the wireless communication interface is a time division duplex communication interface or a frequency division duplex communication interface.

Meanwhile, in order to overcome the defects, the invention also builds a self-adaptive short video content enhancement method, which comprises the step of using the self-adaptive short video content enhancement system for determining the corresponding image content enhancement strategy based on the target richness degree in the short video picture.
In addition, frequency division duplex means that uplink and downlink transmissions are performed on different frequencies. In the first and second generation cellular systems, FDD technology is basically used for duplex transmission. In particular, in the first generation cellular systems, since continuous baseband signals are transmitted, duplex uplink and downlink channels must be provided using different frequencies. In the first generation cellular systems, in which FDD is used for continuous information transmission, frequency synthesizers for generating different carrier frequencies are required at both the transmitting and receiving ends, and a duplex filter for preventing the transmission signal from leaking to the receiver is required at the receiving end. In addition, in order to facilitate the fabrication of the duplexer, a certain frequency interval is required between the transmission and reception carrier frequencies. In the second generation of systems such as GSM, IS-136 and IS-95, FDD technology IS also used. In these systems, since the information is transmitted in time slots, the transmission and reception can be performed in different time slots, and the transmission signal of the mobile station or the base station does not interfere with the receiver. So, despite the FDD technique employed, no expensive duplex filters are required.
The FDD mode is characterized by receiving and transmitting in two symmetric frequency channels separated (190 MHz between uplink and downlink frequencies), and separating the receiving and transmitting channels by guard bands. By adopting the technologies of packet switching and the like, the bottleneck of the second generation development can be broken through, the high-speed data service can be realized, the frequency spectrum utilization rate can be improved, and the system capacity can be increased. FDD must provide third generation services using paired frequencies, i.e., within a bandwidth of every 2x5 MHz. The mode can fully utilize the uplink and downlink frequency spectrums when supporting the symmetric service, but the frequency spectrum utilization rate is greatly reduced (about 40 percent of the frequency spectrum utilization rate is reduced due to low uplink load) when the asymmetric packet switching (Internet) works, and in this regard, the TDD mode has incomparable advantages compared with the FDD mode.
