Embodiment 1

[0048] The image transmission process described in this embodiment involves the following parts:

[0049] (1) As the mobile phone camera device or camera monitoring equipment as the sending terminal, its function is mainly to provide the initial image resource for the E module to provide image processing objects;

[0050] (2) The mobile phone as the receiving end is used to accept the image transmitted by the network, and then perform the decompression operation described in (3) to the image;

[0051] (3) The image compression and decompression technology used in the existing image transmission of mobile phones or networks mainly completes the compression of images at the sending end and decompression of images at the receiving end;

[0052] (4) The image transmission medium network, connecting the sending end and the receiving end, as an intermediary for image transmission;

[0053] (5) The implementation module of image downsampling and deformation (moving and rotating), ma...

Embodiment 2

[0058] This embodiment is based on the system configuration described in Embodiment 1, and describes the detailed processing process of the image transmission method, including the following steps:

[0059] In the first step, at first in the (1) module, that is, as the mobile phone camera device or camera monitoring equipment as the sending terminal, an initial image resource (such as a picture) is obtained;

[0060] In the second step, the (5) module deforms (moves and rotates) and down-samples the image to obtain a sequence of low-resolution images. Because of the influence of the camera and the environment or the optical factors of the sensor, the sequence of low-resolution images There will be a blur effect. Of course, this also depends on the current processing of the image acquired by the camera equipment itself, and the existence of noise. These factors must also be considered in the image restoration algorithm;

[0061] The third step is to obtain the sequence image th...

Embodiment 3

[0064] This embodiment takes a specific super-resolution restoration method as an example, and describes the detailed processing process of the image transmission method, including the following steps:

[0065] Step 1. Obtain an image from the mobile terminal as the sender, and then follow the Figure 7 The method of rotating and downsampling the image, Figure 7 What is shown is actually to establish an observation model from high-resolution to low-resolution images. Considering that it is an operation on the existing images, the receiving end restores the images. If the angle of each rotation is set in the coordinate system is θ, the displacement is x′, y′ in the coordinates x and y directions respectively (the rotation angle and displacement can be randomly set and obtained each time), sampling every other pixel, that is, the downsampling coefficient is 2, then after The resolution of the image obtained after this process is 1 / 4 of the original image; if you want to restor...

Abstract

The invention discloses an image transmission method and an image transmission system. The method comprises that: a transmitting terminal acquires a frame of original image and acquires M low-resolution images according to the original image, wherein the resolution of each of the M low-resolution images is 1 / N of the resolution of the original image and M is smaller than N; the transmitting terminal transmits M low-resolution images to a receiving terminal; and the receiving terminal restore the original image by a super-resolution restoration means according to the M low-resolution images. The invention provides a novel scheme for reducing network resource expense by reducing the transmission size of the image, thereby allowing for better utilization of network resources, providing a considerable point for the selection of the terminal, and developing an application mode more close to daily life for the super-resolution restoration technology.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an image transmission method and system. Background technique [0002] When a terminal transmits an image through the network, since the size of the image is often relatively large, it will occupy more network resources, and in addition, it will bring relatively large traffic overhead to the terminal user. Therefore, in the related art, in order to solve this problem, an image compression technology is often used to compress the image. [0003] Image compression technology generally compresses the original image (without losing image pixels) using an image compression algorithm. After the terminal compresses the image, the compressed image is transmitted through the network. The impact of the transmission of such compressed images on network resources is largely limited by the use of image compression techniques. [0004] It can be seen that in the related technologies, the ...
