Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Referring to fig. 1, a schematic flow chart logic diagram illustrating a data processing method provided by the present disclosure is shown. In the method, after acquiring a target image, an encoder searches a target image sequence corresponding to the target image according to a pre-stored image sequence, encodes the target image according to the target image sequence, and then sends the encoded target image to a decoder, and the decoder searches the pre-stored image sequence according to the encoded data, searches the target image sequence corresponding to the identification information of the target sequence, and decodes the target image according to the target image sequence. Specifically, the left storage logic schematic and the right storage logic schematic are both the correspondence between the reference frame of each image sequence and the sequence number of each image sequence, the left storage logic schematic is stored in the memory 1, and the right storage logic schematic is stored in the memory 2. In the scenario that the decoder and the encoder are close to each other, a memory may be used, which may be determined according to actual situations.
Example one
The disclosed embodiment provides a data processing method, as shown in fig. 1, the method is applied to an encoding device, and the data encoding method includes the following steps:
101. and acquiring a target image to be coded.
The target image in the method provided by the disclosure can comprise a terminal device remote control server, and the server responds to the remotely operated interface image; the method also comprises the step that the terminal equipment accesses a server, and the server sends the desktop image.
The obtaining of the target image in the method provided by the present disclosure may be that the server obtains an interface image responding to an operation instruction of the terminal device, and sends the target image to the terminal device, so as to achieve a technical effect of remotely controlling the server through the target image, and specifically, the target image may be encoded through an encoder in the server.
102. According to a preset algorithm, when a target image sequence containing the target image is found in at least one preset image sequence, a preset reference frame and target sequence identification information corresponding to the target image sequence are obtained.
The preset image sequence may include a historical operation interface image of the server.
The method provided by the disclosure further comprises the step of creating a preset image sequence, wherein the preset image sequence can be generated according to the image with the utilization rate higher than the threshold value in the history record, and can also be generated according to the operation interface image of the target software in the server. For example, a preset image sequence is generated according to a word software toolbar image, when a server transmits a word operation interface image to a terminal device, the probability of change of the toolbar image is smaller than a threshold value, and is not changed in the daily use process, so that when the toolbar image is coded and transmitted, the preset image sequence can be used as a coding reference image, and the coding data amount is reduced.
Further, in the method provided by the present disclosure, sequence identification information may be generated for the preset image sequence, and the preset image sequence may be identified by the sequence identification information, so that a plurality of preset image sequences may be distinguished by the sequence identification information, where the sequence identification information may be a sequence number.
After the preset image sequence is generated in the method provided by the disclosure, the image characteristic value corresponding to the preset image sequence and the preset reference frame of the preset image sequence are also obtained, and the mapping relation between each preset reference frame and each preset image sequence is established.
In a specific implementation, the method provided by the present disclosure may establish a corresponding relationship between preset image sequences and image feature values by establishing a table, where each image sequence is respectively labeled by a sequence number, as shown in fig. 3 a: as can be seen from the table lookup, the image feature value corresponding to the image sequence number 1 is the a feature value, and the image sequence corresponding to the image sequence number 1 is the image sequence a.
Further, the method provided by the present disclosure may further establish a corresponding relationship between the reference frame of each image sequence and the sequence number of each image sequence by establishing a table, as shown in fig. 5b, by looking up the table, it can be known that: the reference frame corresponding to the image sequence number 1 is an A reference frame, and the image sequence corresponding to the image sequence number 1 is an image sequence A.
The method provided by the present disclosure can compare the target image frame with a preset image sequence through the image feature value, so as to determine whether the target image belongs to the preset image sequence, and the specific determination method includes:
in the step, firstly, extracting an image characteristic value of a target frame image, wherein the target image characteristic value of the target image can be extracted from the target image by using a perceptual Hash algorithm, such as a-Hash, p-Hash, d-Hash and the like;
searching in the corresponding relation between the preset image sequence and the image characteristic value according to the extracted target image characteristic value, wherein the specific search can be searched by a table in fig. 3 a;
if the target frame image can be found, the image sequence to which the target frame image belongs is a preset target image sequence, and a preset reference frame corresponding to the preset target image sequence can be used for coding;
if not, it indicates that the image sequence to which the target frame image belongs is not a preset image sequence, and cannot be encoded by using a reference frame corresponding to the preset image sequence.
The target image frame is found in the preset image sequence, and the target image frame can be determined according to the difference between the two images: when the difference between the image feature value extracted from the target frame image and the image feature value extracted from the preset image sequence is smaller than the preset feature value threshold, the target frame image can be considered to belong to the image sequence corresponding to the preset image feature value.
It can be understood that images with image feature values belonging to the same image sequence are all similar. The same reference frame can be used for interframe coding, the image quality is higher, and the code stream is smaller. Even in a scene of page switching, the image sequence of the image can be found according to the image characteristic value of the image, and then the reference frame corresponding to the image sequence can be found.
For example, an a-Hash algorithm is used to extract an image feature value, and the preset feature value threshold may be a hamming distance (the hamming distance between 2 vectors is defined as the percentage of different components of the 2 vectors), and specifically, the threshold may be set to (0.25); the image feature value extracted from the target frame image a is (1010101010), the image feature value corresponding to the preset image sequence a is (1010101011), and as can be seen, the hamming distance between the two is (0.1), and is smaller than the preset feature value threshold, it can be considered that the target frame image a belongs to the image sequence a.
In the specific implementation process, if the preset image sequence comprises a plurality of images, the preset image sequence can be compared one by one to confirm that the specific image comprises the target frame image
The finding of the reference frame corresponding to the target image sequence in the method provided by the present disclosure may include:
according to the sequence identification information of the target image sequence to which the target image belongs, the reference frame corresponding to the sequence identification information is searched in the database, and the corresponding relationship between the reference frame of at least one image sequence and the sequence number identification information of at least one image sequence is stored in the memory of the specific server in advance, so that the reference frame corresponding to the target image can be searched through the sequence identification information, and the specific search can be searched through the table in fig. 3 b.
103. And performing interframe coding on the target frame image according to the preset reference frame and the target sequence identification information to generate coded data.
The method for inter-frame coding the target image to generate coded data includes:
acquiring sequence identification information corresponding to the target preset image, wherein the sequence identification information can be a serial number of an image serial number;
and generating the coded data after marking the preset reference frame by the sequence identification information.
By the sequence identification information, the decoding device can find the reference frame used when the target image is coded, so that the decoding efficiency is improved.
According to the method, when the target image is not found in the preset image sequence, a new image sequence is generated according to the target image, and coding processing is carried out. And the encoder performs intra-frame encoding on the target data to generate encoded data, wherein the encoded data carries the sequence identification information of the new image sequence.
It will be appreciated that the encoder will only perform intra-frame encoding if the image to be encoded belongs to a new image sequence, and the encoded data will only include the reference frame.
After a new image sequence is created, the method provided by the disclosure can send the new image sequence and the identification information thereof and the reference frame image to the encoding device, thereby ensuring that the same reference frame can be used for encoding and decoding, and achieving the effect of improving the encoding and decoding processing efficiency.
In a specific practical process, an encoder in a server creates and stores a new image sequence, the target image belongs to the new image sequence, and the target image and identification information corresponding to the target image are sent to a memory; the memory stores the target image as a reference frame of a new target image sequence.
After the memory receives the target image and the sequence number of the target image sequence, the memory stores the target image as a reference frame of a new target image sequence, and establishes a corresponding relation between the reference frame of the new image sequence and the sequence number of the new image sequence.
The data processing method provided by the embodiment of the disclosure is applied to an encoding device, when the encoding device acquires a target image, a target image sequence including the target image is firstly searched in at least one preset image sequence, when the target image sequence is searched, a preset reference frame corresponding to the target image sequence is acquired, and the target image is encoded according to the preset reference frame.
In the method provided by the disclosure, each preset image sequence corresponds to a reference frame, and when the same image sequence is coded, the reference frame corresponding to the image sequence is used for coding; meanwhile, the reference frames corresponding to the image sequences are saved in the decoding equipment, and the reference frames corresponding to the image sequences are used for decoding the coded data of the same image sequence. Therefore, under the scene of image switching, different reference frames are respectively used for images belonging to different image sequences so as to ensure the picture quality, and in addition, the reference frames in the coded data sent to the decoding end by the coding end are less, so that the coded data amount is smaller.
Example two
Based on the data encoding method provided by the embodiment corresponding to fig. 2, another embodiment of the present disclosure provides a data decoding method, which can be applied to a terminal device to decode a target image sent by a processing server. Referring to fig. 4, the data processing method provided in this embodiment includes the following steps:

The coded data refers to a target image which is coded and processed, and the coded data comprises target sequence identification information of a preset image sequence; the target sequence identification information may include a sequence number of the target image sequence, thereby facilitating finding the target image sequence among a plurality of stored preset image sequences.
In a specific practice, the acquired encoded image in the method provided by the present disclosure may be encoded data sent by a terminal device decoding processing server, where the encoded data may be data obtained by performing encoding processing on an interface image acquired by the server in response to an operation instruction of the terminal device, and specifically, the encoded image may be decoded by a decoder in the terminal device.
The encoded data provided by the present disclosure includes a target image and target sequence identification information, where the target sequence identification information is used to indicate a preset image sequence corresponding to the target image.
302. And according to the target sequence identification information, when the target image sequence corresponding to the target sequence identification information is found in a preset image sequence, acquiring a preset reference frame corresponding to the target image sequence.
In the decoding method provided by the present disclosure, a preset image sequence list is stored, where the preset image sequence list includes image sequences and each image sequence corresponds to a sequence number, as shown in fig. 5a, it can be known through table lookup that: the image sequence with the image sequence number 1 is the image sequence a.
In the decoding method provided by the present disclosure, the correspondence between the reference frame of each image sequence and the sequence number of the corresponding image sequence of each image sequence is also stored, as shown in fig. 5b, it can be known through table lookup that: the reference frame corresponding to the image sequence number 1 is a reference frame a.
In summary, in the decoding method provided by the present disclosure, the first corresponding relationship between the identification information and the preset image sequence is consistent with the second corresponding relationship between the identification information and the reference frame image corresponding to the preset image sequence. For example, the preset image sequence a corresponding to the sequence number 1 may be found in fig. 5a and 5b by using the sequence number 1, or the reference frame a corresponding to the sequence number 1 may be found by using the sequence number 1, that is, it can be known that the reference frame a is a reference frame corresponding to the preset image sequence a.
When judging whether the identification information has a corresponding preset image, the method searches the reference frame corresponding to the sequence number in the pre-stored correspondence between the reference frame of each image sequence and the sequence number of each image sequence according to the sequence number of the image sequence analyzed from the encoded data, and the processing process comprises the following steps:
analyzing the coded data, and acquiring identification information according to an analysis result;
according to the identification information, searching whether a target image sequence matched with the identification information exists in a preset image sequence list;
if the target image sequence matched with the identification information is found, acquiring a reference frame image corresponding to the target image sequence;
if the target image sequence corresponding to the data to be decoded is not found, the preset image sequence does not include the target image sequence corresponding to the data to be decoded, the encoded data is generated by intra-frame encoding, and a reference frame required for decoding the encoded data is not stored in the memory 2.
In the method provided by the present disclosure, when a target image sequence corresponding to the target sequence identification information is not found in a preset image sequence, a target image sequence may be created according to encoded data, which specifically includes:
decoding the coded data to obtain a complete target image;
creating a new image sequence according to the target image and the target sequence identification information, and establishing a mapping relation between the target sequence identification information and the new image sequence;
and storing the target image sequence, the target sequence identification information and the mapping relation into a second memory.
Furthermore, a new target image sequence can be processed, the target frame image is used as a reference frame corresponding to the target image sequence, and a mapping relation between the reference frame and the target sequence identification information is established
Through the above processing, the decoding method provided by the present disclosure may determine, according to the identification information carried in the encoded data, such as the sequence number, that the new target image sequence is included in the preset image sequence list when the encoded data generated by inter-frame encoding through the target image sequence is encountered next time, and then obtain the required reference frame from the memory 2 according to the identification information.
303. And decoding the coded data according to the preset reference frame to obtain a target frame image.
The method provided by the present disclosure decodes the encoded data by using the preset reference frame to obtain a complete target image.
Furthermore, in order to improve the decoding efficiency, the present disclosure may further replace the reference frame corresponding to the target image sequence in the correspondence relationship by the target image, and through the replacement processing, the reference frame corresponding to each image sequence stored in the memory may be continuously updated, so that the image during encoding and decoding is as close as possible to the reference frame, which not only can reduce the encoded data, but also can improve the image quality of the decoding processing.
In the specific practice process of the method provided by the disclosure, the complete image obtained by decoding and the serial number of the resolved image sequence can be sent to the memory through the decoder; the memory replaces the reference frame corresponding to the sequence number of the analyzed image sequence with the complete image, that is, the decoded complete image is used to update the reference frame of the image sequence to which the complete image belongs.
