By using 10 groups of training data which were collected through testing a cellphone in order to find the overall functions in it, a size estimation model was built by using Mathematics, a tool to help implement a fitting method for the parameters in COCOMO model. By invoking the FindFit function and using the least square method, the parameters were fixed. With two groups of test data, the size estimation...
Aiming at tracking Closely Spaced Objects (CSO) from Infrared (IR) images, an algorithm is proposed based on probability hypothesis density (PHD) filter incorporating the signal amplitude feature. With the influence of the Point Spread Function (PSF) and limited resolution of IR Focal Plane Array (FPA) resulting in unresolved measurements problem, an image preprocessing is firstly used to detect and...
To solve the problem of prediction accurately cost in software cost estimation, a new method of software project life cycle cost estimate algorithms was proposed, based on Fuzzy rules dealt with multi-level discrete neural network structure and HCM clustering algorithms. A new software projects were divided into two apart: with similarity and without similarity. For the cost of former, fuzzy clustering...
It is an important index to projectile burst location in weapon system, to research projectile burst location distributing; the method of mathematical statistics hypothesis was put forward to analyze their distributing law. In this paper, the theory of projectile burst location was analyzed, and according to projectile burst location data by measure system, mathematical statistics hypothesis testing...
It is difficult to obtain analytical solution to forward kinematics for parallel mechanism, and the speed of the solution based on conventional numerical solution method is lower, and hard to achieve real-time performance in motion control. In this paper, in order to avoid the two problems, a continuous on-line estimation algorithm was proposed to approach the forward kinematics analytical solution...
This work presents a robust method for realtime segmentation and tracking of moving objects using depth image sequences, which is insensitive to illumination changes. We propose a novel criterion in our quadtree split-and-merge framework and effectively solves the problem of segmenting objects in complex and cluttered scenes. We also introduce a plane estimation algorithm to cope with the indistinction...
In order to reduce the influences of synchronization signals in CMMB (China Mobile Multimedia Broadcasting) system, which caused by multipath and frequency offset in wireless channel. This paper combined the specific frame structure of CMMB standard protocol, analyzed some influences for symbol synchronization, and proposed a coarse symbol timing synchronization algorithm that was based on traditional...
