Research focused on Video and 3D LiDAR point cloud data compression and processing.

• Development of efficient 3D LiDAR compression methods using octree-based, graph-wavelet, statistical, hierarchical, and deep-learning techniques to reduce spatial and statistical redundancy.
• Improvement of compression performance through Morton coding, arithmetic coding, Karhunen-Loeve Transform (KLT), Lloyd–Max quantization, Bloom Filters, t-distributed Stochastic Neighbor Embedding (t-SNE), Density-Based Spatial Clustering of Applications with Noise (DBSCAN), K-Dimensional (K-D) Trees, and neural-network-based feature learning, targeting reduced file size, faster processing, and better rate–distortion performance.
• Development of a unified and scalable compression framework for large-scale 3D LiDAR point clouds that preserves essential geometric and attribute information while reducing storage, bandwidth, and computational requirements for real-world applications.
• Implementation & Evaluation: Implemented the proposed methods using Python/Anaconda Jupyter Notebook and evaluated them using compression ratio, file size, PSNR, MSE, RMSE, BPP, and reconstruction quality.
