Full Consideration

The choice of the motion features affects the result of the human action recognition method directly. Many factors often influence the single feature differently, such as appearance of human body, environment and video camera. So the accuracy of action recognition is limited. On the basis of studying the representation and recognition of human actions, and giving full consideration to the advantages and disadvantages of different features, this paper proposes a mixed feature which combines global silhouette feature and local optical flow feature. This combined representation is used for human action recognition.

This paper presents a synthesis method for the open path generation of a four-bar mechanism using the Haar wavelet. The synthesis method utilizes the wavelet transform and normalization to extract the wavelet output feature parameters (WOFP) of the open path. Analysis of the WOFP reveals a particular characteristic: for the same four-bar mechanism, not only do variations of the mechanism origin and angles and the proportional scaling of the linkage lengths have no influence on the details of the WOFP but the same holds true for the position of the point that generates the coupler curve. Based on this finding, a numerical atlas database comprises 192,596 groups of basic dimensional types was established and a method of matching recognition was proposed as well. According to the internal relationship of the wavelet characteristic dimension parameters (WCDP), the actual mechanism parameter values and position parameters of an objective four-bar mechanism can be calculated. Four examples are presented to verify the accuracy and practicality of the proposed theory.

Prime Source

Dioscorides's De materia medica from the first century AD was for about 1,800 years the most influential work and prime source in all matters concerning drugs and pharmacy. Originally written in Greek, the book was soon translated into Latin, thereby changing its structure from a systematic arrangement in five books according to the internal relationship of the drugs to a simply alphabetical order by the first letter of the name. Such an alphabetical order was also retained in the first printed version of the work in 1478. This edition was praised by recent researchers because of its supposed new material, by others, however, it was criticized severely with respect to its general set-up. The present paper discusses both opinions and substantiates some other neglected details regarding the 1478 edition. Besides the 1478 edition the amended new edition from 1512 is analysed too.
