Image Compression Method Based on QR-Wavelet Transformation
In this paper, a procedure is reported that discuss how linear algebra can be used in image compression. The basic idea is that each image can be represented as a matrix. We apply linear algebra (QR factorization and wavelet transformation algorithms) on this matrix and get a reduced matrix out such that the image corresponding to this reduced matrix requires much less storage space than th...
متن کاملComments on “An Image Encryption Scheme Based on Rotation Matrix Bit-Level Permutation and Block Diffusion”
Recently, an image encryption scheme based on rotation matrix bit-level permutation and block diffusion was proposed [Y Zhang, D Xiao. Commun Nonlinear Sci Numer Simulat. 2014, 19:74-82]. In this paper, this image encryption scheme was studied in detail and its defects of low encryption speed and weak security were pointed out. This scheme with one round was crypt-analyzed successfully with the...
متن کاملImage Encryption Using Fibonacci-Lucas Transformation
Secret communication techniques are of great demand since last 3000 years due to the need of information security and confidentiality at various levels of communication such as while communicating confidential personal data , patients’ medical data, countries’ defence and intelligence information, data related to examinations etc. With advancements in image processing research, Image encryption...
متن کاملAn Efficient Memristor based Image Encryption Algorithm
Contemporary inquisition on numerous schemas of FPGA endeavoring curtailment of power consumption effectuates the inference that one of the utmost expansively used contexts is Static Random Access Memory (SRAM) based structures. This paper addresses the limitations associated with SRAM such as low density, longer routing path, increased propagation delay, increased peak power consumption rate a...
متن کاملAn Image Encryption Algorithm Based on Multi-Dimensional Orthogonal Sequence
This paper proposes a new approach for image encryption using multi-dimensional orthogonal sequence. The sequence can provide an orthogonal transform for digital data, which is useful for image encryption. The key to decrypt is a set of the parameters to generate the sequence. For a gray scale image and a binary image, four different sequences are used to encrypt. Two of them are used to encryp...
