A hybrid chaos map with two control parameters to secure image encryption algorithms
Roghayeh Hosseinzadeh, Yavar Khedmati, Reza Parvaz
In this paper, we introduce a hybrid chaos map for image encryption method with high sensitivity. This new map is sensitive to small changes in the starting point and also in contr…
Four-dimensional hybrid chaos system and its application in creating a secure image transfer environment by cellular automata
R. Parvaz, Y. Khedmati, Y. Behroo
One of the most important and practical researches which has been considered by researchers is creating secure environments for information exchanges. Due to their structures, chao…
Color image restoration with impulse noise based on fractional-order total variation and framelet
Reza Parvaz
Restore lost images due to noise and blurred is a burgeoning subject in image processing and despite the different algorithms on this subject, but the effort to improve is always c…
A new type of 4D Hybrid Chaos Systems
Reza Parvaz
In this paper a new type of chaotic system based on sin and logistic systems is introduced. Also the behavior of this new system is studied by using various tests. The results of t…
2D Hybrid chaos map for image security transform based on framelet and cellular automata
Y. Khedmati, R. Parvaz, Y. Behroo
In this paper, we provide some safe ways to transfer images securely by using cryptography and steganography methods. In order to enhance the security of the image transmission, we…
Multi-color image compression-encryption algorithm based on chaotic system and fuzzy transform
M. Zarebnia, R. Kianfar, R. Parvaz
In this paper an algorithm for multi-color image compression-encryption is introduced. For compression step fuzzy transform based on exponential b-spline function is used. In encry…
