In the feature classification mentioned in the third chapter, the distance measurement adopts the method of the shortest distance, and the nearest neighbor rule is used in distance measurement The algorithm proposes a novel method of measurement, optimization--select the best from the good ones, which has been proven by the experiment to be correct and effective to improve the recognition rate.
To reduce the influence of the noise and occlusion, a novel distance measurement method is proposed, in which first order statistics of the close points between the template and the image are used as a matching measurement.
With the precondition that the geometrical relationship and the distance measurement among data be kept unchanged, we can map manifold corresponding to the original data in high dimension space into that in low dimension space so that not only is the data quantity reduced in future relative calculation, but also disturbance of the noise is removed, which highly improved the precision and efficiency of pattern recognition.
In frequency modulated continuous wave radar sensors, which are widely used in industrial contactless distance measurement applications, the usage of the Fourier Transformation for signal evaluation is very common.
To achieve a highly accurate distance measurement, attention must be paid to various error sources.
Long distance measurement of the meteoparameters of a cloudy atmosphere by radiometry
An example is given of distance measurement performed by means of electromagnetic waves in the optical range.
A scheme for applying the method of distance measurement is considered, based on the solution obtained.
