Detailed Description
In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
First, some terms appearing in the description of the embodiments of the present application are applied to the following explanations:
h.265: HEVC (High efficiency video coding), a new generation of High efficiency video coding.
YUV: color space adopted by video standards, Y (brightness information), U/V (color difference information).
4:4:4: lossless video sampling format.
4:2:2: lossy video sampling format.
RAM: random Access Memory, random Access Memory.
DDR: namely Double Data Rate SDRAM, SDRAM sampled by upper and lower edges.
Pixel: representing a minimum unit of constituent picture elements.
Color depth: i.e., color depth, represents the number of bits of a single pixel color.
Currently, in the related art, when image processing is performed, the entire processing flow is as shown in fig. 1. Firstly, a video signal is obtained from a video signal source, then the video signal is decoded to obtain a video image in a lossy video sampling format, then the image in the lossy video sampling format is up-sampled to obtain an image in a lossless video sampling format, then the image in the lossy video sampling format is preliminarily processed, the image quality problems such as noise and the like possibly existing in the video image are eliminated, and the resolution and the like of the image are preliminarily adjusted. And then storing the preliminarily adjusted image into a storage module, acquiring the preliminarily processed image from the storage module according to the actual needs of the user, and processing the image again. Before sending the video image to the user, in order to ensure the transmission efficiency, the video image needs to be downsampled to obtain the video image in the lossy sampling format, and then the video image in the lossy sampling format is encoded.
With reference to fig. 3, it can be understood that, when a video image in a lossless video sampling format is processed in the related art, for each pixel point, data on the YUV three components needs to be processed, which results in excessive data amount to be processed, and thus the video processing speed is relatively slow. In addition, in the related art, a certain time is consumed for performing one up-sampling and one down-sampling on the video image, and the video processing rate is further reduced.
In addition, with reference to fig. 2 and fig. 4, it can be seen that, when storing a video image in a lossless video sampling format, since data of each pixel point on the YUV three components needs to be stored, when storing the same video image, a storage space required by the video image in the lossless video sampling format is much larger than that of the video image in the lossy video sampling format. As can be seen from fig. 2, in order to ensure the speed of the image processing flow, the storage module is usually a RAM or a DDR, so that the method for processing the video image in the lossless video sampling format in the related art needs a large storage space, which results in high cost.
In order to solve the technical problems of slow image processing flow rate and high cost in the related art, in the embodiment of the present application, a method embodiment of an image transmission method is provided, it should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.
It should be noted that the image transmission method provided in the embodiment of the present application may be applied to a relay node in a video transmission system, where the relay node is configured to obtain a video signal from a video signal source, process the video signal, and send the processed video signal to different video playing terminals. The transfer node can be provided with a communication module for receiving and sending video signals, a first processing module for performing primary processing on images, a second processing module for performing secondary processing on the images, a storage module for storing the primarily processed images, and an encoding module and a decoding module for encoding and decoding videos. It should be noted that the first processing module, the second processing module, the encoding module, and the decoding module may be independent processors, or may be different functional modules on one processor.
Fig. 5 is an image transmission method according to an embodiment of the present application, as shown in fig. 5, the method including the steps of:
step S102, acquiring a first target image, wherein an image format of the first target image is a lossy image sampling format:
it should be noted that the first target image and the second target image described in this application may be separate images, or may be a video composed of consecutive multi-frame images.
Step S104, performing image processing on the first target image to obtain a second target image, wherein in the process of performing image processing, the image formats of the first target image are all lossy image sampling formats, and the image format of the second target image is also a lossy image sampling format;
in the technical solution provided in step S104, the process of performing image processing on the first target image to obtain a second target image includes: acquiring a first target video signal; decoding the target video signal to obtain the first target image; determining an image processing method corresponding to the first target image; and processing the first target image according to the image processing method to obtain a second target image.
Specifically, the entire image transmission flow is as shown in fig. 6. After a first target video signal is received and decoded to obtain a first target image, the image transmission method provided by the application does not sample the first target image, changes the image format of the first target image, but directly performs image processing on the first target image, then stores the processed first target image into a storage module, performs image processing on the first target image stored in the storage module again to obtain a second target image, then encodes the second target image to obtain and output a second video signal, wherein the video format corresponding to the second video signal is a lossy sampling format.
Specifically, in the process of encoding and decoding, h.265 codec rules may be adopted for encoding and decoding.
As will be understood from the image processing flow shown in fig. 6, in the image processing process, in order to increase the transmission rate of the video, the video signal is obtained from the video signal source, which is usually encoded. After the input first video signal is acquired, the first video signal needs to be decoded to obtain a video picture in order to further process the video. For example, for a video signal whose encoding scheme is the h.265 scheme, the first video signal may be decoded by the corresponding h.265 decoding scheme. It should be noted that h.265 is only used for understanding the image processing flow, and does not mean that the h.265 decoding method must be used to decode the video signal in the solution provided in the present application.
After decoding is completed, since the decoded video image does not necessarily meet the actual needs of the user, the image needs to be further processed. In the process of processing the image, because the requirements of different users are inconsistent, the image can be firstly subjected to primary processing, and then the image after the primary processing is subjected to secondary processing according to the requirements of different users.
Specifically, the image may be repaired or adjusted when the image is preliminarily processed. The repairing of the video image comprises repairing problems of noise, bright lines and the like in the video image, and the adjusting of the image comprises adjusting the resolution and the like of the video image. It should be noted that, when performing the preliminary processing on the video image, a plurality of image processing methods may be used to process the video image together, for example, the video image may be repaired first and then adjusted.
Because different users have different requirements, the image after the primary processing needs to be stored in the storage module and processed again according to the requirements of different users. Specifically, the re-processing of the image includes adjusting the resolution or the like of the video image. Then, in order to ensure the transmission rate, the processed image may be encoded to obtain a second video signal, and the video information is sent to video playing terminal devices corresponding to different users.
As can be seen from fig. 1 and 6, compared with the related art, the present application can effectively improve the processing efficiency of the video image because the step of converting the image format twice is omitted.
It can be understood that, before the first target image is subjected to image processing twice, a corresponding processing method needs to be determined, where determining the image processing method corresponding to the first target image includes: determining an image feature type of the first target image, and determining a first image processing method corresponding to the image feature type; and determining an image output format selected by the target object, and determining a second image processing method corresponding to the image output format.
As an optional implementation manner, processing the first target image according to the image processing method to obtain a second target image includes: processing the first target image using a first image processing method; sending the processed first target image to a storage module; and acquiring the processed first target image from the storage module, and processing the processed first target image by using the image processing method to obtain the second target image.
Specifically, the image characteristics of the first target image include a fault type of the first target image, such as noise, bright lines, etc. in the image. At this time, the first image processing method may be an image restoration method for restoring the first target image. In addition to image restoration, the first image processing method may be an image quality improvement algorithm or the like for improving the image quality of the first target image.
It is to be understood that the pixel information corresponding to any pixel point in the first target image and the second target image includes brightness information and any one of first color difference information and second color difference information.
Specifically, as an alternative embodiment, the image types of the first target image and the second target image may be YUV types, and the image formats of the first target image and the second target image may also be denoted by 4. Under the picture format, each pixel point in the first target image and the second target image only stores the Y component in the YUV three components and one of the U component and the V component. The image processing flow at this time is as shown in fig. 7, and it can be seen that in this case, since only two components need to be considered per pixel, the bandwidth requirement is reduced by 1/3 compared to the related art in which an image of a lossless sampling format is processed.
In addition, the lossy sampling format may also reduce the need for storage resources. Fig. 8 is a schematic diagram of an image storage method provided according to an embodiment of the present application. As can be seen from the figure, assuming that the size of the storage space is 1024 bits, the color depth of each pixel is assumed to be 8 bits, the storage space can store 1024/(8 × 2) =64 pixels, and for the image pixels in the lossless sampling format stored in the related art, the storage space can only store 1024/(8 × 3) =42.6 pixels. Compared with the storage space consumption in the related art, the total storage space consumption is 4:2: the 2 link can store 64-42.6=21.4 color depth pixels more in the same storage space as the 444 link. It can be seen that the video transmission method provided by the application can effectively reduce the requirement on storage resources.
And step S106, outputting a second target image.
In some embodiments of the present application, when outputting the second target image, the second target image needs to be decoded, so as to obtain a second target video signal, where a video format of a video corresponding to the second target video signal is a lossy sampling format.
The method comprises the steps of obtaining a first target image, wherein the image format of the first target image is a lossy image sampling format: performing image processing on the first target image to obtain a second target image, wherein the image formats of the first target image are lossy image sampling formats and the image format of the second target image is a lossy image sampling format in the image processing process; the method for outputting the second target image achieves the purpose of avoiding the image format conversion in the image processing process by not changing the image format of the target image in the image processing process and always adopting the lossy image sampling format, thereby realizing the technical effect of reducing the requirements of bandwidth resources and logic resources, and further solving the technical problem of more bandwidth resources and logic resources required by the image processing flow caused by the fact that the image in the lossy video sampling format needs to be converted into the image in the lossless video sampling format in the image processing in the related technology.
