  • Detection of motion - target based on improved gradient vector flow snake model
    基于改進(jìn)梯度向量流形變模型的動(dòng)目標(biāo)檢測(cè)方法
  • We discuss several different definitions of directional derivative and gradient vector
    摘要討論了幾種不同的方向?qū)?shù)和梯度的定義。
  • The gradient vector can be used to construct the initial errors
    這時(shí)可以對(duì)梯度向量本身進(jìn)行分析，或者用這個(gè)梯度向量構(gòu)造初始誤差場(chǎng)。
  • Adjoint method provides an efficient tool to calculate the gradient vector of the cost function to the initial field
    利用伴隨方法，可以求出該度量函數(shù)關(guān)于初始場(chǎng)的梯度向量。
  • Therefore the gvf ( gradient vector field ) is used to substitute the traditional potential field and it overcomes the defects of the traditional active contour
    于是，我們采用一種梯度向量流場(chǎng)作為外力，從而有效地克服了傳統(tǒng)勢(shì)能場(chǎng)的弱點(diǎn)，給曲線的移動(dòng)以很好的指向。
  • When using modem optimization methods , the gradient vector information of the target function is not necessary , so there is much flexible in solving complex optimization problems
    使用現(xiàn)代優(yōu)化技術(shù)時(shí)不需要目標(biāo)函數(shù)的梯度向量，因此在解決復(fù)雜優(yōu)化問題時(shí)有更大的靈活性。
  • 2 . study the working principle of the vector transducer , mainly for two - dimensional pressure - gradient transducer . and the experimental results for directional pattern of two - dimensional pressure - gradient vector transducer at frequency 3khz and 5khz are given
    重點(diǎn)對(duì)本文所要研究的壓差式矢量水聽器進(jìn)行研究，并運(yùn)用消聲水池實(shí)測(cè)數(shù)據(jù)繪出了二維壓差式矢量水聽器在3khz和5khz下的指向性圖。
  • To corner feature , both gradient magnitude change and direction change of gradient vector are discontinuity in a local image neighborhood , hence gradient - direction variation and gradient magnitude are used as another decision rule of the corner detection to improve antinoise
    為了提高抗噪聲,根據(jù)角特征不僅灰度變化是不連續(xù)的,且相對(duì)周圍其他點(diǎn)的梯度方向也是不連續(xù)的,提出利用梯度角變化和梯度幅值作為角特征檢測(cè)的另一個(gè)準(zhǔn)則。
  • There are two methods to optimize the parameters and structures of neuro - fuzzy networks : one is the differential coefficient optimization method based on gradient vector ; the other is based on modern optimization methods , such as genetic methods , simulated annealing etc , in which , the researches on genetic methods are most prominent
    目前，對(duì)模糊神經(jīng)網(wǎng)絡(luò)的權(quán)值或結(jié)構(gòu)進(jìn)行優(yōu)化的方法有兩類：一類是基于梯度向量的導(dǎo)數(shù)優(yōu)化方法；第二類方法是基于現(xiàn)代最優(yōu)化技術(shù)的非導(dǎo)數(shù)優(yōu)化方法，如遺傳算法、模擬退火算法等，其中以遺傳算法的研究最為突出。
