Network - based anomaly dectection systems have advantages such as early detecting and novel attack detecting 其中,基于網(wǎng)絡(luò)的異常檢測具有能發(fā)現(xiàn)新攻擊、能及早做出響應(yīng)等優(yōu)勢。
Therefore the dynamical characteristic is acted as detected parameter for fractured detection ( primary amplitude secondary frequence ) . and the amplitude of mean sguare and central frequence are acted as evaluational parameter , based on the those studies , the new ideas is put forward that fractured azimuth is dected by lateral difference and fractured density is dected by vertical difference for three facters of fracture , wavelet acted as analysis tool and direction by wave field characteristic applied the multiple scale edge dectection and self - adaptive edge detection into the detection theory of seismic fractured azimuth , also put forward the wavelet different scale filter method of the fractured azimuth detection 因而,確定了主要以振幅,其次是頻率的地震波動力學(xué)特征作為裂縫檢測的被檢參數(shù)和均方振幅和中心頻率作為檢驗(yàn)檢測結(jié)果正確與否的評價參數(shù)。在上述研究基礎(chǔ)上,針對裂縫的三要素,提出通過橫向求異檢測裂縫方位和縱向求異檢測裂縫密度的新思想。并以小波作為分析工具,以潛山波場特征作指導(dǎo),將數(shù)字圖像處理中的多尺度邊緣檢測和自適性邊緣檢測引用到地震裂縫方位檢測中來,并提出了小波變尺度濾波法新的裂縫方位檢測法。
