High resolution digital elevation models (DEM) are utilized in automatic extraction of single-trees in mixed forests. In this paper the digital surface models (DSM) provided from aerial images with resolutions of 8 cm and 20 cm and airborne laser scanning ALS data are investigated. The results showed a relative good representation of the tree crowns even in(More)
—The aim of this work is to increase the instability of the marching-on-in-time (MOT) method that is used in the analysis of wide-band electromagnetic pulse scattering from structures made of thin wires. The stability problem has been identified with the advent of the MOT method in 1991, and although several improvements have been suggested to overcome this(More)
The paper gives a short overview about the existing data base and extraction methods for single tree detection. Forest remote sensing has a long tradition and a variety of methods for single tree extraction have already been developed. Most studies and methods focus either on the analysis of satellite images or airborne laser data and on the extraction of(More)
In 21 complete denture wearers, six upper and 15 lower denture relines were performed with the open-mouth technique. The centric relation (CR) was recorded with the Central-Bearing-Point (CBP) method three times before and three times after the reline. For each registration, the right and left condylar position was recorded in three dimensions using a(More)
