Title:
METHOD FOR ESTABLISHING VIRTUAL REFERENCE FRAME, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/090600
Kind Code:
A1
Abstract:
Disclosed are a method for establishing a virtual reference frame, and a device, which relate to the field of image processing and can solve the problems in the prior art of virtual reference frame establishment leading to a decoder being relatively complex and having high power consumption or an extra code rate being needed for transmission. The specific solution involves: receiving at least one image frame transmitted by an encoder; and establishing a virtual reference frame by using a block, in the at least one image frame, with a virtual reference frame identifier. As a virtual reference frame identifier is added to a block for establishing a virtual reference frame, the transmission of a virtual reference frame is not needed during a transmission process, this avoiding a rise in code rate. Moreover, the decoder only needs to extract the block with the virtual reference frame identifier to form a virtual reference frame, and does not need to establish the virtual reference frame based on an image frame and by using an algorithm identical to that of the encoder, thereby reducing the complexity and power consumption of a decoder. The present application is used for establishing a virtual reference frame.
