Embodiment Construction

[0043] The present invention provides a USDC data processing method. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be described in further detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0044] The present invention provides a USDC data processing method, such as figure 1 As shown, it includes the following steps:

[0045] Including the color image wavelet decomposition step, using super complex wavelet transform to decompose the input image into sub-images of different frequencies, where the low-frequency sub-image is an approximation of the original image, and the high-frequency sub-images in three directions reflect the details of the original image Information, retain the color information of the color image;

[0046] Including vector coding steps, using super-com...

Abstract

The invention discloses a USDC data processing method which comprises the following steps of color image wavelet decomposition, wherein hypercomplex wavelet transform is adopted, and color information of color images is maintained; vector encoding, wherein a hypercomplex cluster analysis process is adopted, and human eye sensitive information content in the images is maintained; motion compensation, wherein asymmetric crossed multilevel hexagonal-grid improved search is adopted, classification is carried out according to motion intensity, and compressed bit flow is obtained; finally the compressed bit flow is output through a network. The technological mode of combination of the color image wavelet decomposition, the vector encoding and the motion compensation is adopted, so that video transmission code flow becomes small, video images are compressed according to the image conditions, bandwidth is greatly saved, delay is reduced, and operating cost is saved.

Description

Technical field [0001] The invention relates to the field of video image coding in the computer field, in particular to a USDC data processing method. Background technique [0002] At present, the de facto video coding standard in the world is the H.264 / MPEG-4AVC standard of the United States, which is a block-oriented lossy video compression standard based on motion compensation. H.264 is developed by ITU-T (ITU Telecommunication Standardization Sector, International Telecommunication Union Telecommunications Standardization Group) Video Coding Expert Group (VCEG) and ISO / IEC Motion Picture Expert Group (MPEG) jointly formed by the Joint Video Team (JVT, Joint Video Team) to propose a highly compressed digital video codec standard. H.264 is one of the ITU-T standards named after the H.26x series, and AVC is the name of the ISO / IEC MPEG side. This standard was officially adopted as an international standard at the 7th JVT meeting held in Pattaya, Thailand in March 2003. Since ...
