climate change disturbs the distribution of precipitation patterns and affects water resources. a lot of evidences imply that the increased atmospheric concentration of greenhouse gasses in turn increases the precipitation changes around the world. thus, since iran is located in an arid zone of the earth, identifying the effects of co2 concentrations on iran precipitation rate is highly importa...

This paper presents a new approach to Dynamic Texture (DT) classification based on the spatiotemporal analysis of the motion. The Grey Level Co-occurrence Matrix (GLCM) is modified to analyse the distribution of the magnitude and the orientation of the Optical Flow which describes the motion. Our method is therefore called Combined Co-occurrence Matrix of Optical Flow (CCMOF). The potential of ...

In this paper we present a technique for the summarization and spatiotemporal scaling of video content. A Self Organizing Map (SOM) neural network can be used o acquire a rough generalization of the spatiotemporal trajectories of moving objects, in the form of few selected nodes along these trajectories. We introduce a hybrid technique, combining SOM with geometric analysis to properly densify ...
