Abstract

The invention discloses a storage processing method and device for image data. The storage processing method for the image data comprises the steps that hierarchical coding is carried out on the image data to be stored to obtain hierarchical coded data of multiple data layers of the image data to be stored; Hash calculation is carried out on the hierarchical coded data of each data layer to obtain an abstract corresponding to each data layer; the hierarchical coded data of the multiple data layers are stored, and correspondence relationships are built among the abstracts of the hierarchical coded data of the multiple data layers. The storage processing method for the image data can manage the hierarchical coded data respectively, thereby being capable of taking the hierarchical coded data of different data layers as needed to process the hierarchical coded data conveniently, releasing the storage space and resolving the problem that stored images occupy a large space. In addition, Hash calculation is carried out on the hierarchical coded data of each data layer to obtain the abstract, relation management is carried out on the abstracts, and therefore the stored data are prevented from being tampered.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular to a method and device for storing and processing image data. Background technique [0002] In the field of security monitoring, video-based video storage systems usually require a huge amount of data storage space to retain surveillance video, which is defined in the video coding standard H.264 and SVAC (Surveillance Video and Audio Coding, security monitoring digital video and audio codec) standards A scalable video coding (Scalable Video Coding, SVC) tool is used. The coding output of SVC is base layer (Base Layer, BL) and enhancement layer (Enhance Layer, EL) data. The resolution of BL in space and time is low, occupying The storage space is small; EL can provide a clearer and smoother surveillance video picture, and its decoding process needs to refer to the corresponding BL, and it will pay the price of significantly increasing the storage space. In the p...
