g-frame representations with bounded operators
Yavar Khedmati, Fatemeh Ghobadzadeh
Dynamical sampling, as introduced by Aldroubi et al., deals with frame properties of sequences of the form , where belongs to Hilbert space $\h…
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…
Invertibility of Multipliers for Continuous G-frames
Yavar Khedmati, Mohammad Reza Abdollahpour
In this paper we study the concept of multipliers for continuous -Bessel families in Hilbert spaces. We present necessary conditions for invertibility of multipliers for continu…
Disjointness of continuous g-frames and Riesz-type continuous g-frames
Yavar Khedmati, Mohammad Reza Abdollahpour
In this paper we introduce concepts of disjoint, strongly disjoint and weakly disjoint continuous -frames in Hilbert spaces and we get some equivalent conditions to these notion…
