چکیده
A lightweight encryption technique for JPEG2000 with optional support for transparent encryption is proposed. Randomized anisotropic wavelet packet bases are used to construct a secret frequency domain, leading to a situation in which only a minimal amount of data needs to be encrypted. Results and calculations are presented to evaluate the suggested approach in terms of compression performance, security, and applicability.

Singular Value Decomposition based Steganography Technique for JPEG2000 Compressed Images
In this paper, a steganography technique for JPEG2000 compressed images using singular value decomposition in wavelet transform domain is proposed. In this technique, DWT is applied on the cover image to get wavelet coefficients and SVD is applied on these wavelet coefficients to get the singular values. Then secret data is embedded into these singular values using scaling factor. Different com...

Nowadays, we all have seen that use of internet has become very important to all the generations. So, large amount of data has been shared through internet. So, important information that has been travelling through internet can be copied by an unauthorized user. To avoid this type of problem Digital Watermarking Technique has been used. In this paper watermarked image has been developed using ...
متن کاملThe Performance Of Fractal Image Compression On Different Imaging Modalities Using Objective Quality Measures
In the arena of, high speed data transmission and requirement of large data to store in minimum available space, compression is very prominent aspect. There are various techniques, which have been applied for this purpose. One of most useful technique is fractal image compression. In which the main errand is to lessen the transmission time and storage capacity. In this paper, the primary object...
متن کاملPlanelet Transform: A New Geometrical Wavelet for Compression of Kinect-like Depth Images
With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...
متن کاملError-rate Based Power-controlled Multimode H.263-assisted Video Telephony
The performance of a power-control algorithm suitable for multi-mode transceivers is investigated using 1, 2 and 4 bit/symbol modems. It is shown that the algorithm is suitable for maintaining a target frame error rate, irrespective of the modulation mode employed. The transceiver parameters are summarised in Table 1, while the minimum and maximum required average transmitted powers in the cell...
