A cornerstone of evolutionary theory is that the phenotypic variance of a population may be partitioned into genetic and environmental (nonheritable) components. The traditional motivation for this distinction is that the rate of evolution under natural selection depends on the (relative) magnitudes of certain genetic components of variance. The components of variation are also interesting from...

A technique that automatically locates specific facial points on an unknown face image is presented. This technique uses log Gabor wavelets to represent each facial point by embedding local surrounding features. Using a sample log Gabor response of a facial point, locations on the unknown face image that appear similar to the sample facial point are detected. We identify facial points by employ...

The measurement of ground control points is an important task for the absolute orientation of stereo models, for digital aerial triangulation or for the registration of satellite imagery. In the Digital Photogrammetric Systems existing today this task is usually completely performed by a human operator. There exist, however, methods, that can identify and/or localize control points or control s...

Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...

Nowadays the tenor of reports on applications of digital photogrammetric procedures consists of a unison message: processing modules of automatic image orientation are available in digital photogrammetric systems and with them the productivity is much higher than with all existing conventional photogrammetric plotters. In fact, interior and relative orientation procedures as well as automated a...

The first step in Active Shape Model (ASM) based image segmentation and processing is to create a point distribution model (PDM) during the training phase. Correct point (landmark) correspondences across each of the training shapes must be determined for a successful and effective statistical model building process. Effective and automatic solutions for this problem are needed for the practical...

In this paper, we propose a new seed projection method for solving shifted systems with multiple right-hand sides. This seed projection method uses a seed selection strategy. Numerical experiments are presented to show the efficiency of the newly method. Keywords—shifted systems, multiple right-hand sides, seed projection.

In this paper we present a fast three dimensional computed tomography system in combination with automatic 3d image processing, which gathers necessary information for production control of sugar beet seed. We outline the design of the inspection system and the three dimensional image processing. Within one hour the geometrical parameters of more than 1000 seeds (about 3-4 mm diameter) are meas...
