SIFT (Scale Invariant Feature Transform) is one of most popular approach for feature detection and matching. Many parallelized algorithms have been proposed to accelerate SIFT to apply into real-time systems. This paper divides the researches into three different categories, that is, optimizing parallel algorithms based on general purpose multi-core(More)
A Support Vector Machine (SVM) based method for land and sea segmentation in Polarimetric SAR (POLSAR) is proposed in this paper. The principle of SVM is first briefly summarized. Features that selected for SVM consist of 9 polarimetric features obtained from polarimetric target decompositions, i.e., Krogager, Freeman-Durden and Cloude decompositions, and 6(More)
In Cartesian coordinate systems, the angular separation-based star identification algorithms involve much trigon-ometric function computing. That delays the algorithm process. As in a polar coordinate system, the coordinates are denoted by angular values, it is potential to speed up the star identification process by adopting a polar coordinate system. An(More)
Traditional star identification algorithms use the angular separations as the identification feature, but the similar matches resulting from similar triangles degrade the identification efficiency and delay the process. To enhance the performances of the star identification algorithm, the information of the star magnitudes in star images is used to add a(More)
Two of the most significant factors in the success of todaypsilas system-on-chip (SoC) designs are the ability to deliver efficient access to off-chip high speed memory and the ability to be compatible with several different interface-timings of several different sorts of memories. And the scheduling scheme of data streams for multi-master and(More)
