• The compression algorithm based on bit plane transform is proposed
• An image wavelet compression algorithm based on zerotree and bit plane
• The algorithms researchof information hidden based on bit plane decomposition
• The calculation of the bit plane transform is operation of bit mainly . the algorithm can be realized by hardware
• This algorithm may avoid leaking out secrets caused by bit plane filtering because hidden information is not embedded in fixed bit - plane of load ' s image
• Every pixel generates a bit data after front half of the clock cycle , then the pixel array generate a bit plane which is stored in sam
• The difference is considered in the bit plane transform . calculation is spent on removing the spectral correlation of higher bit plane images
• At first we construct a new image transform : bit plane transform . we study on the property of bit plane transform and the application in hyperspectral image compression
• The technique constructs bpof based watermark from the image discrete fourier transformation and embeds the watermark into the bit plane ( s ) of the corresponding magnitude spectrum
• For hyperspectral image , different bit plane images have different spectral correlation . the higher bit plane images have strong correlation while the lower bit plane images have weak correlation
• The compression algorithm based on bit plane transform can be realized by parallel computing model . the calculation for high bit data and low bit data are independent . there is n ' t communication and synchronization in the whole process
• It improves the calculation efficiency greatly and saves processing time . the calculation complexity of compression algorithm based on bit plane transform is o ( n ) , n is the number of pixels in the image . the compression ratio of algorithm is more than 1 . 9

• Combining the favorable capability of ebcot and characteristic of multi - wavelet ’ s coefficients , this article puts forward an integrated filter and pretreatment method based on approximated stairs . it processes the vector quantification of multi - wavelet ’ s coefficients and carries out the mix - scan compression arithmetic towards bit planes of ebcot
• Introducing gray structuring elements dilation to the classification of wavelet coefficients , producing different significance for different clustering and benefiting for fractional bitplane coding . suggesting decompose encoded ll subband to get seed coefficients of dilation firstly . at the beginning of each bit plane coding the seeds is acquired , by the within - subband and cross - subband dilation of over significant pixels and significant pixels
• It ' s reviewed for the coefficient classification of existing wavelet image encoding technologies . wavelet coefficient is clustered with gray structuring elements dilation and outputted in the form of fractional bit plane according to the different significance . zero tree structure is used to employ cross - subband dependency to promote the coding effort
• Since 3d - pcw tackles the coefficients as a whole , the context of a coefficient is computed only once , and the coefficient is encoded only once . but in 3d - escot the context has to be computed once and the coefficent has to be encoded once on every bit plane . therefore , 3d - pcw has much lower time complexity than 3d - escot
