The Discrete Cosine Transform (DCT) is fundamental to high-capacity data hiding schemes due to its ability to condense signals into a few significant coefficients while leaving many high-frequency coefficients relatively insignificant. These high-fre

The use of reinforcement learning (RL) for dynamic obstacle avoidance (DOA) algorithms and path planning (PP) has become increasingly popular in recent years. Despite the importance of RL in this growing technological era, few studies have systematic

Path quality and computational time have formed together a well-known trade-off problem for path planning techniques. Due to this trade-off, contributions were usually considering improving only one of the two aspects, either increasing the swiftness

The traditional trade-off between execution speed and path quality has forced real-time robotic path planning algorithms to sacrifice path quality in order to execute in real-time. Producing a path planning algorithm that targets enhancing both, the

This paper introduces the concept of a pixogram which makes possible a fresh approach to high payload video steganography. The pixogram allows for a new perspective by investigating the temporal changes that take place at the individual pixel level a

Dealing with the trade-off challenge between computation speed and path quality has been a high-priority research area in the robotic path planning field during the last few years. Obtaining a shorter optimized path requires additional processing sin

It has been proven that the strong energy compaction property of the Discrete Cosine Transform (DCT) has a relation with the inter-pixel correlation level in the spatial domain of the cover image. Recent studies have proven that the higher the correl

There has always been a trade-off between embedding capacity and stego quality, and due to this, current research in image steganography suffers either from low embedding capacity in order to preserve high stego image quality, or from sacrificing the
