partitioning

This toolbox contains Matlab code for several graph and mesh partitioning methods, including geometr

This toolbox contains Matlab code for several graph and mesh partitioning methods, including geometric, spectral, geometric spectral, and coordinate bisection. It also has routines to generate recursive multiway partitions, vertex separators, and nested dissection orderings and it has some sample meshes and mesh generators. The toolbox contains a Matlab interface to Leland and Hendrickson s Chaco partitioning package, but it doesn t contain Chaco itself. The file "chaco/README" tells how to install the interface to Chaco. It also contains a Matlab interface to Karypis et al. s Metis partitioning package, using Robert Bridson s "metismex" code.

cskmeans 聚類算法的一種 1. 分裂法(partitioning methods)：給定一個有N個元組或者紀錄的數據集

cskmeans 聚類算法的一種 1. 分裂法(partitioning methods)：給定一個有N個元組或者紀錄的數據集，分裂法將構造K個分組，每一個分組就代表一個聚類，K<N。而且這K個分組滿足下列條件：（1）每一個分組至少包含一個數據紀錄；（2）每一個數據紀錄屬于且僅屬于一個分組（注意：這個要求在某些模糊聚類算法中可以放寬）；對于給定的K，算法首先給出一個初始的分組方法，以后通過反復迭代的方法改變分組，使得每一次改進之后的分組方案都較前一次好，而所謂好的標準就是：同一分組中的記錄越近越好，而不同分組中的紀錄越遠越好。使用這個基本思想的算法有：K-MEANS算法、K-MEDOIDS算法、CLARANS算法；

基于FPGA的靜止圖像編碼器

遙感圖像在人類生活和軍事領域的應用日益廣泛，適合各種要求的遙感圖像編碼技術具有重要的現實意義。基于小波變換的內嵌編碼技術已成為當前靜止圖像編碼領域的主流，其中就包括基于分層樹集合分割排序(Set partitioning inHierarchical Trees，SPIHT)的內嵌編碼算法。這種算法具有碼流可隨機獲取以及良好的恢復圖像質量等特性，因此成為實際應用中首選算法。隨著對圖像編碼技術需求的不斷增長，尤其是在軍事應用領域如衛星偵察等方面，這種編碼算法亟待轉換為可應用的硬件編碼器。在靜止圖像編碼領域，高性能的圖像編碼器設計一直是相關研究人員不懈追求的目標。本文針對靜止圖像編碼器的設計作了深入研究，并致力于高性能的圖像編碼算法實現結構的研究，提出了具有創新性的降低計算量、存儲量，提高壓縮性能的算法實現結構，并成功應用于圖像編碼硬件系統中。這個方案還支持壓縮比在線可調，即在不改變硬件框架的條件下可按用戶要求實現16倍到2倍的壓縮，以適應不同的應用需求。本文所做的工作包括了兩個部分。 1．一種基于行的實時提升小波變換實現結構：該結構同時處理行變換和列變換，并且在圖像邊界采用對稱擴展輸出邊界數據，使得圖像小波變換時間與傳統的小波變換相比提高了將近2.6倍，提高了硬件系統的實時性。該結構還合理地利用和調度內部緩沖器，不需要外部緩沖器，大大降低了硬件系統對存儲器的要求。 2．一種采用左遍歷的比特平面并行SPIHT編碼結構：在該編碼結構中，空間定位生成樹采用深度優先遍歷方式，比特平面同時處理極大地提高了編碼速度。

DN460雙輸出降壓穩壓器優化效率

The LTC3546 is a dual output current mode buck regulatorwith fl exible output current partitioning. Beyondthe advantages normally associated with dual outputregulators (reduced size, cost, EMI and part count, withimproved effi ciency), the LTC3546’s outputs can bepartitioned for either 3A and 1A outputs, or two 2A outputs.This increases its application range and simplifi esmultiple supply rail designs. A confi gurable Burst Mode®clamp for each output sets the current transition levelbetween Burst Mode operation and forced continuousconduction mode to optimize effi ciency over the entireoutput range. An adjustable switching frequency up to4MHz and internal power MOSFET switches allow forsmall and compact footprints.
