Table 3: Comparative results are presented as maximum bbp/dB values for the different methods, with the highest capacity values highlighted in bold. such as slow-motion video. This property allows for efficient energy compaction, concentrating the majority of the signal's energy into a few significant coefficients while leaving a large area of insignificant ones. The rationale behind the proposed Octree technique is to exploit this property strategically. By targeting the large area of insignificant coefficients generated by the DCT, the Octree method provides a structured and efficient way to hide secret data. This approach not only increases the hiding capacity but also minimizes visual or perceptual degradation, as the hidden data resides in areas that contribute minimally to the overall signal quality. The hierarchical structure of the Octree further enhances the efficiency of this technique. It allows for precise localization and adaptive utilization of the insignificant coefficients, ensuring that the embedding process is both scalable and robust. This combination of the DCT's compaction ability and the Octree's hierarchical design results in a technique that achieves higher capacity for data-hiding while maintaining lower degradation in the signal, making it ideal for applications requiring both high data concealment and quality preservation. In host video segments with fast-motion content, temporal redundancy is reduced compared to slow-motion segments, which can lead to diminished performance. However, the proposed Octree scheme demonstrates better resistance to performance degradation in fast-motion scenarios. This is because the Octree scheme leverages both spatial and temporal redundancy. While fast-motion segments may offer less temporal redundancy, the spatial redundancy within individual frames still contributes significantly to the overall redundant information. Consequently, the Octree scheme compensates for the lack of temporal redundancy by utilizing spatial redundancy, thereby effectively hiding larger amounts of secret data. Tables 4-6, Tables 7-9, and Tables 10-12 show the results obtained with the proposed Octree-hiding scheme when hiding using the three different video segments \"Monitoring\", \"Documentary\", and \"Film\", respectively, with different motion content. Based on Tables 4-6, Tables 7-9, and Tables 10-12, the proposed Octree scheme has achieved outstanding results that reached up to hiding with 23.16 bpp while achieving a carrier quality of 34.64 dB. This result was obtained when hiding the into the \"Film\" segment while setting the \(C\) threshold value to 0.95.
