Advances in space and computer technologies are revolutionizing the way remotely sensed data is collected, managed and interpreted. The development of efficient techniques for transforming the massive amount of collected data into scientific understanding is critical for space-based Earth science and planetary exploration. Although most currently available parallel processing strategies for hyperspectral image analysis assume homogeneity in the computing platform, heterogeneous networks of computers represent a very promising cost-effective solution expected to play a major role in the design of high-performance computing platforms for many on-going and planned remote sensing missions. This paper explores techniques for mapping morphological hyperspectral analysis algorithms, characterized by their scalability and sub-pixel accuracy, onto heterogeneous parallel computers. Important aspects in algorithm design are illustrated by using both homogeneous and heterogeneous parallel computing facilities available at NASA's Goddard Space Flight Center and University of Maryland. Experiments reveal that heterogeneous networks of workstations represent a source of computational power that is both accessible and applicable in many remote sensing studies

Transitivity is an important property used in logical reasoning. However, Part-Whole (PW) relations usually do not satisfy the property. Wiston and Odell partitioned PW relations into six sub-PW relations respectively, such that the transitivity property is held in each sub-class and each different sub-PW denotes a kind of PW relations with special meanings. This paper studies the composition of different sub-PW relations given by Wiston and Odell in following three aspects: (I) Does the composition relation of two different sub- PW relations make sense?(2) Is the transitivity still held for the composition relations of two different sub- PW relations; (3) which sub-PW class does the composition relation belong to. Different from former study, a formal discussion is carried for above issues.

In this paper we present how face tracking can be implemented on mobile devices. Our main contribution is to present how face tracking on mobile systems can be used as a multi-dimensional input technique and to demonstrate how this can be used in different mobile applications. We present at set of different applications based on the tracking, and discuss current and future advantages, challenges and problems with face tracking as input device for mobile systems.

Recent parallel systems use multiple injection ports and various injection policies, but little is known about their impact on network performance. This paper evaluates the influence that these injection interfaces have on maximum sustained throughput in adaptive cut-through torus networks by modeling the number of injection queues (1 or 4), and the allocation of new packets to those queues. Network evaluations for medium to large size 2D tori show that designs with multiple injection ports do not improve performance under uniform traffic. On the contrary, they result in more pressure from the injection interface to acquire the scarce network resources of an already clogged system. Interestingly, for small networks, a single injection FIFO queue, with the HOLE it entails, indirectly provides the much needed injection control. For networks with thousands of nodes and multiple injection channels, as those being implemented in current massively parallel processors, this implicit form of congestion control is not enough. In such systems, restrictive injection policies are required to prevent routers from being flooded with new packets for loads beyond saturation.

This paper proposes the method detecting and tracking ships using navigational image sequence taken by the camera installed at ship's bridge. Since an image is influenced by roll and pitch, general image processing technique, such as Background Difference method cannot be applied. Moreover in a navigational image, the sea wave appears as noise. In this paper, we propose a novel technique to eliminate the influence of roll, pitch and sea waves in an image. And we tracked moving ships through navigational image sequence. The image is divided into small regions using brightness value, and these regions are labeled. Each of these regions is considered as a template. The template is assumed to be a ship. Then the template is matched on frames after selected time from an original image. During matching process, the coordinate points are recorded on an Excel table. The moving vector of a region is calculated on an Excel table. We distinguish ships from the character of a moving vector. The detected regions of ships are tagged. Each of the tagged regions is considered as a template and matched on frames after selected time. At this time, the template is replaced by new region to take measures against the change of illumination. The detection processes is started at a suitable interval to prepare for the appearance of another ships. Disappearances of ships are decided by the degree of coincidence of matching. This is the measure to against an occlusion or a frame out of ships. Twelve hours duration of video image have been taken in Tokyo Bay and Tokyo Port, and have been processed by proposal method. It is necessary to extract ship's regions precisely for exact tracking. For that, it is necessary to raise accuracy of extraction. We tried some method to enhance the accuracy of extraction and to prevent incorrect extraction. The result of an effective of measure has described in this paper. The video image that has been taken at Uraga Traffic Route captured several ships. Our
