Special Issue Information

Dear Colleagues,

Machine learning plays an important role in current innovative technology spread across different industry and research areas. Among the wide variety of machine learning models, the more user friendly implementations make it possible to use them in embedded, cloud-based or PC-based systems. An increasing interest in machine-learning-based algorithm support for various biomechanical systems (e.g. motion tracking, parametric analysis of rehabilitation progress), healthy lifestyle applications (e.g. virtual assistant, virtual coach), biomedical and other systems opens new perspectives for more powerful and efficient data analysis and processing. However, each specific application introduces individual challenges for machine-learning-based methods. This Special Issue is an opportunity for researchers to share their methods of solving complex issues during investigations in biomechanics, healthy lifestyle and biomedical applications.

Creation of head 3D models from videos or pictures of the head by using close-range photogrammetry techniques has many applications in clinical, commercial, industrial, artistic, and entertainment areas. This work aims to create a methodology for improving 3D head reconstruction, with a focus on using selfie videos as the data source. Then, using this methodology, we seek to propose changes for the general-purpose 3D reconstruction algorithm to improve the head reconstruction process. We define the improvement of the 3D head reconstruction as an increase of reconstruction quality (which is lowering reconstruction errors of the head and amount of semantic noise) and reduction of computational load. We proposed algorithm improvements that increase reconstruction quality by removing image backgrounds and by selecting diverse and high-quality frames. Algorithm modifications were evaluated on videos of the mannequin head. Evaluation results show that baseline reconstruction is improved 12 times due to the reduction of semantic noise and reconstruction errors of the head. The reduction of computational demand was achieved by reducing the frame number needed to process, reducing the number of image matches required to perform, reducing an average number of feature points in images, and still being able to provide the highest precision of the head reconstruction.
