摘要:
Generation of an inappropriate image portion in an orthographic image due to occlusion is prevented. An image processing device includes an image data receiving part that receives image data of multiple photographed images taken by photographing an object from different positions, a coordinate designating part that receives designation of a specific position in the object, and an optimum-condition satisfying image selecting part that selects a photographed image that is taken from a direction in a specific range relative to the specific position, from among the multiple photographed images. The selected photographed image is used to obtain pixel information of the specific position.

A computerized system for displaying, geolocating, and taking measurements from captured oblique images includes a data file accessible by the computer system. The data file includes a plurality of image files corresponding to a plurality of captured oblique images, and positional data corresponding to the images. Image display and analysis software is executed by the system for reading the data file and displaying at least a portion of the captured oblique images. The software retrieves the positional data for one or more user-selected points on the displayed image, and calculates a separation distance between any two or more selected points. The separation distance calculation is user-selectable to determine various parameters including linear distance between, area encompassed within, relative elevation of, and height difference between selected points.

The present invention relates to a method for generating a risk map indicating predicted voxel-by-voxel probability of tissue infarction for a set of voxels, the method comprising the steps of, receiving for each voxel a first value (x) corresponding to a set of tissue marker values and generating the risk map, using a statistical model based on data from a group of subjects, and a stochastic variable, wherein the statistical model also comprises a second value (zi), being based on the stochastic variable, such as the second value modelling non-measured values. The invention may be seen as advantageous since it acknowledges subject variability in probability of tissue infarction on a voxel-by-voxel basis by taking non-measured values into account, which in turn may enable providing more reliable estimates of probability of infarction.

Disclosed are a road line detection method and a road line detection device. The road line detection method comprises a step of obtaining a first disparity map including one or more road regions and a corresponding V-disparity image; a step of sequentially detecting plural sloped line segments in the corresponding V-disparity image according to a big-to-small order of disparities and a big-to-small order of V-values, to serve as plural sequentially adjacent road surfaces; a step of obtaining a second disparity map of plural road line regions of interest corresponding to the plural sloped line segments; and a step of detecting one or more road lines in the second disparity map of the plural road line regions of interest.

摘要:
Die Erfindung betrifft ein Verfahren zum Erzeugen synthetischer Spektren auf Basis einer Mehrzahl realer Spektren; wobei für jedes der realen Spektren eine Mehrzahl von Differenzen der Werte des Spektrums bei verschiedenen Wellenlängen gebildet werden (1 a), sodass eine Mehrzahl von Wertedifferenzen erhalten wird, wobei die Wertedifferenzen jeweils einem Paar unterschiedlicher Wellenlängen zugeordnet sind, wobei für jedes Paar der unterschiedlichen Wellenlängen ein Abweichungsmaß ermittelt wird (1 b), das aussagt, wie stark die dem Paar zugeordneten Wertedifferenzen über alle realen Spektren voneinander abweichen, wobei zumindest ein Paar der unterschiedlichen Wellenlängen ermittelt wird, für das das Abweichungsmaß gemäß einem vordefinierten Kriterium gering ist, d.h. die Werte der realen Spektren dieser unterschiedlichen Wellenlängen in einer stabilen Beziehung zueinander stehen (stabile Wellenlängen)(1 b), und wobei unter Verwendung der Werte der stabilen Wellenlängen als Stützstellen synthetische Spektren berechnet werden (2) und/oder Informationen zur späteren Erzeugung der synthetischen Spektren gespeichert werden (3).
