Embodiment Construction

[0125] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0126] figure 1 It is a schematic diagram of an example of a method of sampling an 8X8 image data at equal intervals in rows and columns in the prior art to generate four low-resolution 4X4 panoramic images. In the figure, it is assumed that the original image data of high-resolution video is 8X8 The data array uses alternate row and column to extract data at equal intervals to generate four 4X4 low-resolution image data. These four 4X4 low-resolution image data contain all the data of the original 8X8 image. Such a data extraction method is that four 4X4 low-resolution image data have strong visual similarity. And any of the 4X4 low-resolution image data is uniformly extracted from the original image, and has visual similarity with the original image.

Abstract

The invention relates to an image information processing method used for video coding and decoding, which includes the steps of decomposing a high resolution video image into a plurality of low resolution panoramic images before compressing and coding, respectively using one low resolution image to multiple by a first weighting efficient and using the rest low resolution images to respectively multiple by all the corresponding weighing coefficients in a second weighing coefficient group according to a plurality of low resolution images with the same resolution, then dividing the sum of the weighting coefficients to generate a plurality of weighted mean images; taking one of the weighted mean images as a reference image and using a correlativity analysis method to obtain the respectively relevant coefficients of the rest weighted mean images with the reference image, thus improving the image quality based on greatly reducing the information volume for implementing data compressing and coding, improving the coding efficiency and improving the transmission efficiency of the video information, and solving the problem of fuzzified image edge to a certain extent.

Description

technical field [0001] The present invention relates to an image information processing method for video encoding and decoding, especially by decomposing the original image information into multiple low-resolution similar image information and adopting a similarity calculation method to reduce the amount of information and the amount of subsequent information encoding / decoding The invention improves information processing efficiency; it belongs to the technical field of image and video encoding / decoding. Background technique [0002] Efficient video codec technology is the key to realize high-quality, low-cost multimedia data storage and transmission. The current popular international standards for image codecs are all based on such a coding theory, using a coding method based on block matching motion compensation, discrete cosine transform and quantization. Typical international standards such as MPEG-1, MPEG-2 and MPEG-4 launched by the first joint technical group of the ...
