AV1 is an open-source video coding technique developed by Alliance for Open Media (AOMedia). Many powerful tools introduced to has made its encoding time significantly increased. In this paper, we aim at simplifying the encoder facilitating selection of some depending on users' specific application preference. We firstly design a tool OFF-test evaluate performance intra, inter, and in-loop filt...

The past years have seen a rapid development in the area of image compression techniques, mainly due to need fast and efficient techniques for storage transmission data among individuals. Compression is process representing compact form rather than its original or incompact form. In this paper, integer implementation Arithmetic Coding (AC) Discreet Cosine Transform (DCT) were applied colored im...

The paper presents a method of creating hidden channel using signals’ superposition. According to this idea, transmitter simultaneously sends overt and covert (secret) signals, whereby the signal is carrier for one. Due need ensure low probability detection communication, should have power. This implies number problems relating its correct reception. similar non-orthogonal multiple access (NOMA...
