Problems solved by technology

[0004] However, the inventors found that in the above method, the transmission delay of the new image is relatively high during the transmission from the server to the terminal, and it needs to occupy a large bandwidth, resulting in low image matting efficiency

Embodiment Construction

[0180] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0181] figure 1 is a structural block diagram of a map-matching system shown according to an exemplary embodiment, such as figure 1 As shown, the system includes a terminal 01 and a server 02, and the communication connection between the terminal 01 and the server 02,

[0182] When the terminal 01 needs to determine the object to be processed from the original image, it can send the original image to the server 02, so that the server 02 can set the transparency and non-transparency of the object to be processed after identifying the object to be processed from the original image. The transparency of the object to be processed is different, and then send the target transparency data of the original image...

Abstract

The invention discloses an image processing method and device. A server identifies a to-be-processed object in the original image, sets the transparency of the non-to-be-processed object in the original image to be different from the transparency of the to-be-processed object, obtains target transparency data of the set original image, and sends out target transparency data. A terminal receives the target transparency data of the original image, and determines a to-be-processed object in the original image according to the target transparency data and the color data of the original image. Therefore, when the server sends the data of the original image on the Alpha channel, the data not which comprises the data on the red channel, the data on the green channel and the data on the blue channel to the terminal, the transmission data volume can be reduced, the transmission time delay can be reduced to improve the matting efficiency, and the network resources can be saved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an image processing method and device. Background technique [0002] Cutout has extensive and in-depth applications in magazine cover, illustration design, advertisement creation, and film and television creation. [0003] Usually, when the terminal needs to determine the object to be processed from the original image, it can send the original image to the server, the server receives the original image, recognizes the object to be processed in the original image, and then returns the original image to the terminal A new image with the same size, and the object to be processed can be indicated in the new image, and the terminal receives the new image. [0004] However, the inventors have found that, in the above method, the transmission delay of the new image is relatively high during transmission from the server to the terminal, and a relatively large bandwidth is re...
