... lattice structures, X-ray computed tomography is employed to scan the printed lattices, and image processing techniques using MATLAB scripts are developed to extract and analyse the characteristics of inspected defects, including their morphology and distribution. Findings This study reveals...

.... Design/methodology/approach A single-camera system captured contour images at checkpoint layers, and image processing algorithms detect geometric deviations. A novel correction strategy balanced overcorrection and undercorrection, ensuring robust error recovery. The system’s effectiveness was validated...

..., measurement possibilities with image processing were investigated to make surface roughness measurements more accessible and more economical. Findings As a result of the tests, the optimum printing condition was decided to be 180–250 µm for layer thickness and 50% for saturation. A separate test sample...

... of a joined-wing test aircraft configuration were fabricated with additive manufacturing and tested in a subsonic closed-loop wind tunnel. Wing deflections were observed during testing and quantified using image-processing procedures. These quantified deflections were then incorporated into numerical...

...Mohammad Vaezi; Chee Kai Chua; Siaw Meng Chou Purpose Today, medical models can be made by the use of medical imaging systems through modern image processing methods and rapid prototyping (RP) technology. In ultrasound imaging systems, as images are not layered and are of lower quality as compared...

... in this research as a light source to generate the photomask image. A set of optical lenses were mounted in front of the DLP to rescale the photomask image. The rescaled photomask image was collected into a computer via a camera. By using the technique of image processing, the actual size of the photomask...

The alternative was to send the information to the Danish Technology Institute (DTI) in Denmark, which claimed that it was able to undertake the required image processing[ 1 ]. It was hoped that a comparison between the alternative...
