3D reconstruction from RGB and RGB-D has a vast range of applications, from medical instruments to autonomous vehicle navigation. A key part of many 3D reconstruction algorithms is the estimation of point correspondences, between different images or 3D models. Since the estimation of point correspondences involves high rates of false matches, outlier rejection is required, usually performed using the RANSAC (Random Sample Consensus) algorithm. It was shown that replacing the sample consensus in the RANSAC algorithm with a feature correlation criterion resulted in a higher probability of a correct estimate. In this project, different 3D reconstruction algorithms were implemented with the feature correlation criterion in the RANSAC algorithm, evaluating the gain in performance accuracy, compared to the standard RANSAC algorithm.

Solar cells are vital for harnessing solar energy; thus, improving solar cell efficiency is crucial. This study explored enhancing solar cells by integrating periodic layers and meta-surfaces to control incident light, improve absorption, and reduce reflection losses. The research focused on optimizing geometries and structural properties to enhance performance. Various material combinations and structures were analyzed using advanced computer simulations to assess their impact on light absorption and scattering. The findings identified a cost-effective, scalable approach that integrates advanced technologies while maintaining industrial compatibility. Practical tests confirmed the potential to improve solar cell efficiency and reduce manufacturing costs, providing a basis for further research.
