Introducing Depth Information Into Generative Target Tracking.

Common visual features used in target tracking, including colour and grayscale, are prone to failure in a confusingly similar-looking background. As the technology of three-dimensional visual information acquisition has gradually gained ground in recent years, the conditions for the wide use of depth information in target tracking has been made available. This study focuses on discussing the possible ways to introduce depth information into the generative target tracking methods based on a kernel density estimation as well as the performance of different methods of introduction, thereby providing a reference for the use of depth information in actual target tracking systems.

Experimental and Analytical Study on Creep Characteristics of Box Section Bamboo-Steel Composite Columns under Long-Term Loading.

To expand the application of bamboo as a building material, a new type of box section composite column that combined bamboo and steel was considered in this paper. The creep characteristics of eight bamboo-steel composite columns with different parameters were tested to evaluate the effects of load level, section size and interface type under long-term loading. Then, the deformation development of the composite column under long-term loading was observed and analyzed.

[Structrue identification of biflavones and determination of Taxol from Taxus Madia].

Objective: To study the flavonoids from Taxus Madia and determine the content of Taxol from different parts of Taxus Madia.

Methods: Various column chromatographic techniques were applied for isolation and purification. The structrues were elucidated by physico-chemical property and spectral evidence.
