We measured vertical and horizontal displacements of distant objects based on the moiré effect. The grid attached to the object was photographed and recorded on video camera. The video was processed later in the lab. The method is self-calibrated an

A three-dimensional (3D) cursor for autostereoscopic 3D displays was proposed. The cursor is based on voxel patterns. In the experiments, the cursor position is interactively controlled in 3D by a computer mouse with a scroll wheel. A computer progra

In this work, two methods are proposed for solving the problem of one-dimensional barcode segmentation in images, with an emphasis on augmented reality (AR) applications. These methods take the partial discrete Radon transform as a building block. Th

The thermal properties of electrically heated carbon-fiber-reinforced mortar prisms with 0.5%, 1.0%, 1.5% and 2.0% of their volumes are investigated. Each prism dimension is 40 mm × 40 mm × 160 mm. When the constant power of 30W is applied to two c

The traces of carbon fibers along the cracked surfaces of mortar prisms, being 40 mm x 40 mm x 160 mm in size, are studied, assuming that the cracked surfaces in the prisms are the places with the lowest resistance to the stresses they are exposed to

The 8-bit RGB image of a cracked concrete surface, obtained with a high-resolution camera based on a close-distance photographing and using an optical microscope, is used to estimate the geometrical parameters of the crack. The parameters such as the

Hyperspectral images in the spectral wavelength range of 500 nm to 650 nm are used to detect green mold pathogens, which are parasitic on the surface of lemons. The images reveal that the spectral range of 500 nm to 560 nm is appropriate for detectin
