第二，在溫熵圖上多條接近水平的線為代表不同氣壓的等壓線，而向右傾斜45度的直線則為等溫線圖三。Neural networks are used more frequently in lossy data coding than in general lossless data coding, because standard neural networks must be trained off - line and they are too slow to be practical. in this thesis, statistical language model based on maximum entropy and neural networks are discussed particularly. then, an arithmetic coding algorithm based on maximum entropy and neural networks are proposed in this thesis
傳統的人工神經網路數據編碼演算法需要離線訓練且編碼速度慢，因此通常多用於專用有損編碼領域如聲音、圖像編碼等，在無損數據編碼領域應用較少，針對這種現狀，本文詳細地研究了最大熵統計語言模型和神經網路演算法各自的特點，在此基礎上提出了一種基於神經網路和最大熵原理的算術編碼方法，這是一種自適應的可在線學習的演算法，並具有精簡的網路結構。In this paper, two kind of wavelet based fusion algorithm of remote sensing images are improved. by experiments on tm images, the improved algorithms are both better than original ones according to the shanon entropy and mean gradient
本文對傳統的基於小波的遙感圖像像素級融合演算法進行改進，並用tm圖像進行實驗，結果表明在信息熵和平均梯度等指標方面，改進后的演算法好於原演算法，起到了優化的作用。( 2 ) a new texture classification algorithm based - on the lifting wavelet transform in suggested utilizing wavelets " perfect performance in spatial - frequency localization and the lifting wavelets " in - place operations. it computes the entropy values of the sub - frequency images disposed by the two - layers " lifting wavelet transform, and has merits of low feature dimensions, low computational cost and good capability
利用小波分析的時頻局域化特性以及提升小波的本位運算等優點，對紋理圖象進行提升小波分解，再對得到的高頻子圖繼續做第二層小波分解，然後以各頻率子圖的圖象熵作為圖象的紋理特徵進行紋理分類。Second, different pressure levels are represented by nearly horizontal lines on the tephigram while constant temperature levels are straight lines tilted at 45 degrees from the vertical ( figure 3 )
第二，在溫熵圖上多條接近水平的線為代表不同氣壓的等壓線，而向右傾斜45度的直線則為等溫線（圖三） 。By dividing fabric image into many windows with the same size, choosing a window with minimum local entropy as a region of interest, thresholding the region and filtering out noise through opening function of mathematical morphology, calculating the defect shape factors as recognition parameters, a algorithm and method of detection of defects in fabric is studied : which has advantages of high identification, correctness, and fast inspection speed mainly because it can avoid complicated calculation of whole image and global searching when the feature parameters are extracted
摘要將織物圖像分成大小相同的局部窗口，選取局部熵最小的窗口為待研究的感興趣區域，在此區域內分割出疵點圖像並用數學形態學中的開運算濾除噪聲，計算疵點形狀因子等作為識別參數，研究表明此方法因能避免對整幅圖像進行復雜運算，在提取特徵參數時對圖像的全局搜索，具有識別正確率高、檢測速度快等優點。分享友人
