Abstract

The invention provides an adaptive network bandwidth hierarchical image transmission method based on content sensitive line cutting. The method comprises the following steps of receiving an image to be transmitted and converting the image into an image matrix; presetting a network reference bandwidth and each stage of network bandwidth interval, and setting a corresponding image clipping amount; obtaining the network bandwidth in the transmission process, and determining the network bandwidth interval to which the current network belongs; determining an image clipping amount; and performing line clipping and transmission on the to-be-transmitted image by using a content-sensitive line clipping method. According to the invention, the method adapts to the network bandwidth during image transmission; based on the analysis of the image content, the important visual content and the significant visual features of the image are reserved, and meanwhile, the visual redundancy or the part with unobvious visual significance is reduced; the data size of image transmission is reduced, the image transmission is ensured to be fast and efficient, the image transmission timeliness is improved, a transmission target end can obtain high-quality images, and support is provided for fast, high-quality and efficient network transmission of the images.

Description

technical field [0001] The invention relates to the technical field of image network transmission, in particular to a content-sensitive line clipping based adaptive network bandwidth hierarchical image transmission method. Background technique [0002] Real-time transmission of images under the environment of limited network bandwidth is an important problem that existing image transmission often faces and needs to be solved. At home and abroad, the real-time transmission of images is mainly analyzed and researched on the situation of not changing the image size and aspect ratio. The conventional method used to reduce the amount of transmitted data is to compress the image. The image is processed by compression coding, which reduces the amount of data and time consumption of image transmission, but it is not easy to maintain the quality of the image, such as clarity. Too high a compression ratio often easily causes block effects and blurring in the image effect. Collective...
