Embodiment 1

[0072] Figure 5 A flow chart of steps of a digital retina-based video coding method according to an embodiment of the present application is shown in .

[0073] like Figure 5 As shown, the video encoding method of this embodiment specifically includes the following steps:

[0074] S101: Acquire an input image, perform inter / intra prediction based on blocks, and obtain first coded prediction data.

[0075] Specifically, after the input image is acquired, the present application also includes a selected encoding region. Therefore, inter-frame / intra-frame prediction is performed based on the block to obtain the first coded prediction data of the coded region.

[0076] S102: According to the input image, perform inter / intra prediction based on the depth prediction model to obtain second coded prediction data.

[0077] Specifically, according to the input image and the selected coding region, inter-frame / intra-frame prediction is performed based on the depth prediction model ...

other Embodiment approach

[0110] In other embodiments, since the accuracy of the depth prediction model depends on its training samples, different models have different prediction results for different image frames. Therefore, the depth prediction model includes multiple models. In the same data frame, the residual calculation module calculates residual values ​​for multiple models, and selects the model with the smallest residual value as the prediction model according to the residual value, and indicates the number of the selected model in the data stream.

[0111] Specifically, namely:

[0112] Simultaneously inputting the same data frame of the image into multiple models of the depth prediction model to obtain a plurality of second inter / intra prediction values; obtaining a plurality of second residual values ​​according to the plurality of second inter / intra prediction values; Selecting the smallest second residual value and the corresponding model among the plurality of second residual values. ...

Abstract

The invention provides a video coding method and system based on a digital retina and a storage medium, and the method comprises the steps: obtaining an input image, carrying out the inter-frame / intra-frame prediction based on a block, and obtaining first coding prediction data; according to the input image, performing inter-frame / intra-frame prediction based on a depth prediction model to obtain second coding prediction data; and when the second coding prediction data volume is smaller than the first coding data volume, coding according to the second coding prediction data. According to the method, the coding compression mode is adaptively selected, the feature extraction capability of the depth model is utilized, redundant information in the image is further compressed, the coding performance is greatly improved, and a higher compression ratio is realized.

Description

technical field [0001] The present application belongs to the technical field of digital signal processing, and in particular relates to a digital retina-based video coding method, system and storage medium. Background technique [0002] Video compression, also known as the concept of digital retina, has attracted great attention in the fields of video codec, video surveillance and so on. In the traditional field of image processing, video compression and video analysis belong to two different fields. Inspired by the biological functions of the human retina, digital retina technology is the first to propose an intelligent image sensor integrating video compression and video analysis. Specifically, the digital retina is characterized by the ability to obtain video compression data and video feature data at the same time, and transmit them to the cloud through data streams for later playback and retrieval. In order to obtain the feature flow of the image, the digital retina t...
