Joint image coding and image authentication based on absolute moment block truncation coding
A joint image coding and image authentication scheme based on absolute moment block truncation coding (AMBTC) is proposed. In the proposed scheme, the authentication data is generated by using the pseudo random sequence. Then, the authentication codes are embedded into the bit maps of AMBTC-compressed image blocks. The embedded bit maps and these quantization levels are further losslessly compr...
متن کاملColour image coding scheme using absolute moment block truncation coding and block prediction technique
A predictive colour image compression scheme based on absolute moment block truncation coding is proposed. In this scheme, the high correlations among neighbouring image blocks are exploited by using the similar block prediction technique. In addition, the bit plane omission technique and the coding of quantisation levels are used to cut down the storage cost of smooth blocks and complex blocks...
متن کاملLow Computational Image Compression Scheme based on Absolute Moment Block Truncation Coding
In this paper we have proposed three and two stage still gray scale image compressor based on BTC. In our schemes, we have employed a combination of four techniques to reduce the bit rate. They are quad tree segmentation, bit plane omission, bit plane coding using 32 visual patterns and interpolative bit plane coding. The experimental results show that the proposed schemes achieve an average bi...
متن کاملInterpolative Absolute Block Truncation Coding for Image Compression
In this paper, an interpolation technique of nearest neighbour base is proposed along with absolute block truncation coding that exploited the spatial domain of low resolution image, and then reversely reconstruct the up layers hierarchically. The results showed the superior performance of compression ratio and image quality compared to traditional absolute block truncation coding.
متن کاملCost Effective Block Truncation Coding for Color Image Compression
In this paper, a cost effective block truncation coding (CE-BTC) using low cost approach is presented for color image compression. To reduce the bit rate of the basic BTC, selected single bit-map is employed to represent the edge information of the coding block in the proposed CE-BTC. Moreover, a previous proposed algorithm, adaptive quantization coding (AQC), is used to compress the two repres...
