Embodiment Construction

[0051] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0052] Such as figure 1 It is a schematic structural diagram of the present invention, a method for realizing a mobile portal based on an improved wavelet transform image compression method, including an encoding part and a decoding part, and the specific steps are as follows:

[0053] The coding part is mainly composed of three basic modules: wavelet transform, quantization and entropy coding. Firstly, the original image is divided into blocks, and each image block is individually upgraded to wavelet transform, and then related quantization and entropy coding are performed, and then the scanning order is followed Write the...

Abstract

The invention relates to mobile internet technical field, in particular to a mobile phone mobile portal method based on improved wavelet-transform image compression method. The portal technology includes an encoding part and a decoding part; the concrete procedures are as follows: the encoding part is composed of three basic modules, namely a wavelet transform, quantification and entropy encoding, wherein the original image is divided into blocks, each image block improves the wavelet transform independently and performs relative quantification and entropy encoding, and then the encoding streams of all image blocks are written into bit streams one by one according to ordered scanning sequence; in decoding end, the data of each image block in the bit stream is performed with entropy decoding, and is written into the corresponding positions of the whole image one by one according to the position relationship of the wavelet coefficient of each image block and the whole image wavelet coefficient, and then the image is recovered through invert quantification and invert improved wavelet transform. The system has the characteristics of easy software and hardware implementation, and pixel scalability.

Description

technical field [0001] The invention relates to the technical field of mobile Internet, in particular to a method for realizing a mobile portal of a mobile phone based on an improved wavelet transform image compression method. Background technique [0002] Mobile Internet has become the latest popular technology. With the popularity of smart phones and the advancement of 3G networks, more and more applications will be applied on it. However, due to the limitations of the mobile phone platform, its functions and processing capabilities will be limited, and so many software cannot be installed like a computer. For example, to realize pdf reading on a mobile phone, it needs software support from Adobe to realize word reading. You need to install the support of Microsoft Office; even if Office word and IE are installed on mobile phones that support the windows Mobile operating system, their functions are still not the same as those on computers. And because the popularization o...
