A convexity theorem for noncommutative gradient flows
      
In this survey we shall prove a convexity theorem for gradient actions of reductive Lie groups on Riemannian symmetric spaces.
      
In the final section the theorem is applied to gradient actions on other homogeneous spaces and we show, that Hilgert's Convexity Theorem for moment maps can be derived from the results.
      
We observe that our methods clearly show that the restriction p>amp;gt;2n/n+1 is closely related to cancellation and size properties of the gradient of the Poisson kernel.

ZS region growing method is proposed for surface feature classification.This method consists of R2 gradient operator processing and two new ways of image processing,thus ensuring high speed and accuracy.Experiments show that the results are correct.The method is especially suitable for surface feature classification of satellite pictures.

本文提出了用于地物分类的 ZS 区域生长法,并据以对东洞庭湖卫星照片(简称卫片)进行了地物分类实验研究。借助无监督分类原则,此法将东洞庭湖卫片划分成水体、湖滩、农田及红土丘陵和芦滩四大部分,同时还给出了各类地物的统计特征值。实验证明,这种分类结果是正确的,它特别适合于卫星照片的大面积地物分类;亦可用于其它需要进行区域分割或分类的领域。

In this paper a gray level-gradient cooccurrence matrix model is presented for the texture analysis and discrimination of an image. And 15 texture parameters are calculated by using this model for each image. The success rate is 77.8 percent by using these texture parameters on a set of 482 samples for classifying five types of white blood cell.
