Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The system architecture of the virtual desktop of one embodiment is shown in fig. 1, and includes: virtual desktop server 101, desktop protocol server 102, and desktop protocol client 103. The desktop protocol client communicates with the server 101 through the desktop protocol server 102, so as to obtain a complete PC usage experience.
Specifically, the virtual desktop server 101 is one of the core components of the virtual desktop system. It is typically deployed on a server and is responsible for creating, managing, and maintaining a virtual desktop environment. The server may integrate with virtualization technology (e.g., VMware, citrix, etc.), generate virtual machines through the virtualization technology, and transmit images of the virtual desktop to the client device.
Desktop protocol server 102 is one of the key components in a virtual desktop system. It is responsible for handling communications between the client and the virtual machine, transmitting images of the virtual desktop to the client device using efficient remote display protocols (such as PCoIP, RDP, or VMware Blast, etc.), and handling user inputs and operations. Desktop protocol services are often tightly integrated with virtualization technology to ensure efficient communication and a smooth user experience.
Desktop protocol client 103 is a device used by a user, such as a computer, tablet, or cell phone. The client communicates with the server through the desktop protocol server, so that complete PC use experience can be obtained. In virtualized desktop solutions, clients need only handle network connections, receive data, and display images of the virtual desktop, without the need to handle complex computing and storage tasks.
The desktop protocol client 103 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The virtual desktop server 101 and the desktop protocol server 102 may be implemented by a separate server or a server cluster formed by a plurality of servers.
Virtual desktop protocols are an important component of cloud desktop products, and efficient utilization of bandwidth is important to provide a smooth user experience and reduce network consumption. There is therefore a need for a new method or system to reduce the consumption of network bandwidth while improving the efficiency and user experience of virtualized desktop protocols.
In one embodiment, as shown in fig. 2, an image processing method of a virtual desktop is provided, and the method is applied to a desktop protocol server in fig. 1 for illustration, and includes the following steps:
step 202, receiving a target image to be sent by a virtual desktop server.
Specifically, the desktop protocol server receives image data to be transmitted by the virtual desktop server 101 to the desktop protocol client 103.
Step 204, sampling the target image to obtain first feature information.
Image sampling is a technique in image processing by which a continuous image signal can be converted into a discrete pixel signal. During image sampling, features of the image, such as edges, textures, colors, etc., may be extracted according to different sampling patterns. In this embodiment, a target image acquisition preset mode is sampled to obtain first feature information.
And step 206, searching for a matched target historical image according to the first characteristic information.
Specifically, according to the first characteristic information, matching is carried out with the characteristic information of the sent historical images, and a matched target historical image is searched. That is, the target history image matches with part of the feature information of the target image.
The transmitted history image may be a last transmitted complete image, i.e. the first feature information is compared with the feature information of the last transmitted complete image. And if so, determining the target historical image.
The transmitted history image may be a complete image within a period of time. And comparing the first characteristic information with the characteristic information of the complete image sent for a period of time, and if the first characteristic information is matched with the characteristic information of the complete image, determining the first characteristic information as a target historical image.
The matching of the first feature information can be quickly matched to similar or identical target historical images based on the features of the sampling points.
Step 208, matching the target image with the target history image to obtain the coordinate information of the same region of the target image and the target history image and the image data of different regions.
Based on the matching of the first characteristic information, it can be considered as coarse screening, at least two of which are characterized as identical at the sampling point. After roughly screening the basically obtained target historical image, matching the target image and the target historical image so as to obtain the same region and different regions of the target image and the target historical image.
For the same region, the coordinate information of the same region is identified, and for different regions, the image data of the target image in the region is acquired.
Step 210, sending the identification of the target historical image, the coordinate information of the same area and the image data of different areas to a desktop protocol client; and the desktop protocol client obtains the target image according to the identification of the target historical image, the coordinate information of the same area and the image data of different areas.
Specifically, the desktop protocol server sends the identification of the target historical image, the coordinate information of the same area and the image data of different areas to the desktop protocol client. That is, the desktop protocol server does not need to send the complete data of the target image to the desktop protocol client, and only needs to send the identification of the target historical image, the coordinate information of the same area and the image data of different areas to the desktop protocol client, so that the data transmission data is greatly reduced, and the occupied bandwidth of the virtual desktop application is reduced.
The desktop protocol client also stores a historical image, and after the identification of the target historical image, the coordinate information of the same area and the image data of different areas are obtained, the target historical image is determined according to the identification of the target historical image, the unchanged area in the target image is determined according to the coordinate information of the same area, and the image data of other areas are replaced with the image data of different areas, so that a target data image is obtained.
According to the image processing method of the virtual desktop, when image data of a server side are sent to a desktop protocol client side through the desktop protocol server side, first, target images to be sent are sampled to obtain first characteristic information, similar target historical images are rapidly screened according to the first characteristic information, then the target images and the target historical images are matched to obtain coordinate information of the same areas of the target images and the target historical images and image data of different areas, and identification of the target historical images, the coordinate information of the same areas and the image data of different areas are sent to the desktop protocol client side; and the desktop protocol client obtains the target image according to the identification of the target historical image, the coordinate information of the same area and the image data of different areas. Therefore, the desktop protocol server does not need to send the complete data of the target image to the desktop protocol client, only needs to send the identification of the target historical image, the coordinate information of the same area and the image data of different areas to the desktop protocol client, and can reduce the data volume of the image data sent in real time, thereby reducing the bandwidth requirement of using the desktop protocol and improving the use experience of users.
In another embodiment, searching for a matching target history image based on the first characteristic information includes: acquiring second characteristic information of the transmitted historical image from the cache; the second characteristic information is obtained by sampling the historical image in a preset mode; and comparing the first characteristic information with the second characteristic information, and if the first characteristic information and the second characteristic information are the same, taking the corresponding historical image as a target historical image.
Specifically, the second characteristic information of the historical sent image is cached in the cache of the desktop protocol server. The second characteristic information is obtained by sampling the historical image in a preset mode. The sampling modes of the first characteristic information and the second characteristic information are the same, so that the characteristic extraction dimensions of the first characteristic information and the second characteristic information are the same, and the matching accuracy is improved.
The desktop protocol server maintains a cache for storing second characteristic information of the historical transmitted image, namely, local information of the transmitted image. Second characteristic information of the transmitted historical image is obtained from the buffer memory. The second characteristic information of the history image sent in a period of time can be obtained from the cache, the first characteristic information and the second characteristic information are compared, and if the first characteristic information and the second characteristic information are the same, the corresponding history image is used as the target history image.
The problem that the original cache hit rate of the virtualized desktop protocol is low and a large amount of network bandwidth is consumed is solved through a local cache mode, so that the user experience is improved under certain bandwidth resources.
In another embodiment, if the target history image matching the first characteristic information is not matched, the target image is sent to the desktop protocol client. I.e. not matching the target history image matching the first characteristic information, it means that there is no transmitted image similar to the target image to be transmitted, and then the complete image of the target image is transmitted to the desktop protocol client. Thus, it is possible to perform the discrimination processing for different types of target images.
In another embodiment, matching the target image with the target history image includes: and expanding the identification area on the target image and the target historical image according to the sampling points of the first characteristic information, and matching the target image and the target historical image according to the expanded identification area.
Specifically, when the first feature information of the target image to be transmitted matches the features of the transmitted history image, the identification area is enlarged on the basis of the sampling points of the first feature information. In one embodiment, the identification area may be enlarged centering on the sampling point of the first feature information, and the matching may be performed based on the enlarged identification areas of the target image and the target history image. For example, the identification area is enlarged with the first feature information point as the center and the first number of pixel point ranges. And comparing the enlarged identification areas of the target image and the target historical image, and if the enlarged identification areas are the same, continuing to center on the first characteristic information and obtaining the enlarged identification areas by using the pixel point range of the second data. The second number is greater than the first number, and thus, by continuously expanding the area and comparing the matching manner, the same area and different areas of the target image and the target history image are rapidly determined.
In another embodiment, matching the target image with the target history image includes: increasing the number of sampling points, and sampling the target image and the target historical image in the same mode to obtain an identification area of the target image and an identification area of the target historical image; the identification area of the target image is matched, and the identification area of the target history image is matched.
In this embodiment, the target image and the target history image are resampled in the same manner by increasing the sampling points. Increasing the number of sampling points may describe the detail information of the image more finely, thereby enlarging the recognition area. By increasing the number of sampling points, information such as the shape, color, texture and the like of the image can be captured more accurately, so that the recognition area is larger. On the basis, the identification area of the target image and the identification area of the target historical image are matched, and the same area and different areas of the target image and the target historical image are determined.
In another embodiment, the image processing method of the virtual desktop further includes: and writing the first characteristic information of the target image into the cache.
That is, the identification of the target historical image, the coordinate information of the same area, and the image data of different areas are sent to the desktop protocol client, or the target image is sent to the desktop protocol client, and the first characteristic information of the target image is written into the cache to store the first characteristic information of the historical target image for comparison of subsequent image processing.
An image processing method of a virtual desktop, as shown in fig. 3, includes:
step 302, receiving a target image to be sent by the virtual desktop server.
Step 304, sampling the target image to obtain first feature information.
Step 306, searching for a matched target historical image according to the first characteristic information.
If so, step 308 is performed to match the target image with the target history image, and obtain the coordinate information of the same region of the target image and the target history image, and the image data of different regions.
If not, go to step 307 and send the target image to the desktop protocol client
After step 308, further includes:
step 310, the identification of the target historical image, the coordinate information of the same area and the image data of different areas are sent to a desktop protocol client; and the desktop protocol client obtains the target image according to the identification of the target historical image, the coordinate information of the same area and the image data of different areas.
Step 307, and after step 312, further includes: and writing the first characteristic information of the target image into the cache.
According to the image processing method of the virtual desktop, updated image data generated by the virtual desktop server side is stored by adopting multidimensional feature images, and the multidimensional feature images are stored in a desktop protocol server side cache queue. When the desktop protocol server generates a new image data, the stored multidimensional image characteristic data is firstly taken from the desktop protocol server cache queue and compared with the newly generated image data. When the multi-dimensional characteristic information is the same, the image data is expanded to identify matching from the multi-dimensional characteristic data position so as to reach the maximum matching image identification area. Then, the desktop protocol server transmits the position information of the maximum image recognition area matched with the multidimensional features to the desktop protocol client, and the real data of the image is not transmitted. And finally, for the same area, the desktop protocol client acquires real image data from the client cache queue according to the transmitted identification position information.
The method caches the whole updated image data by changing the desktop protocol, and adopts multidimensional characteristic image information. In the method, the original whole updated area of the cache is used as the cache, and the efficient image comparison technology of multidimensional features is used, so that the purposes of optimizing a desktop protocol processing mode and reducing bandwidth are achieved. The method improves the efficiency and the performance of the desktop protocol, reduces the use of network bandwidth, and provides a new and effective desktop protocol optimization technology.
The application also provides an image processing method of the virtual desktop, which is applied to the desktop protocol client, as shown in fig. 4, and the method comprises the following steps:
step 402, receiving the identification of the target history image, the coordinate information of the same identification area, and the image data of different identification areas sent by the desktop protocol server.
The desktop protocol server receives a target image to be sent by the virtual desktop server; sampling the target image to obtain first characteristic information; searching a matched target historical image according to the first characteristic information; and matching the target image with the target historical image to obtain coordinate information of the same area of the target image and the target historical image and image data of different areas.
Step 404, according to the identification of the target historical image, the target historical image is obtained from the cache, the unchanged area of the target historical image is determined according to the coordinate information of the same identification area, and the changed area of the target historical image is updated according to the image data of different areas, so as to obtain the target image.
In the method, the desktop protocol server does not need to send the complete data of the target image to the desktop protocol client, and only needs to send the identification of the target historical image, the coordinate information of the same area and the image data of different areas to the desktop protocol client, so that the data transmission data is greatly reduced, and the occupied bandwidth of the virtual desktop application is reduced.
The desktop protocol client also stores a historical image, and after the identification of the target historical image, the coordinate information of the same area and the image data of different areas are obtained, the target historical image is determined according to the identification of the target historical image, the unchanged area in the target image is determined according to the coordinate information of the same area, and the image data of other areas are replaced with the image data of different areas, so that a target data image is obtained.
Specifically, the application modifies desktop protocol servers and desktop protocol clients. At the desktop protocol server, multidimensional feature image information storage and cache queues are mainly introduced. And the desktop protocol client is added with a cache queue which is maintained by the desktop server. The improvement improves the efficiency and the performance of the desktop protocol by optimizing the desktop protocol processing mode, reduces the use of network bandwidth, and provides a new and effective optimization technology for the use of the cloud desktop.
By adopting the method, the desktop protocol server does not need to send the complete data of the target image to the desktop protocol client, only needs to send the identification of the target historical image, the coordinate information of the same area and the image data of different areas to the desktop protocol client, so that the data volume of the image data sent in real time can be reduced, the bandwidth requirement of using the desktop protocol is reduced, and the use experience of a user is improved.
