This will cause the final Pareto optimal frontier perform feature subsets with many features erasing and less improvement of classification rate. In order to improve the accuracy of classification, it is necessary to avoid the over trimming of the features. In this study, we propose a constraint based niched Pareto genetic algorithm to adjust the thread of search.
由於在实际问题中,提升分类准确率,常常会比大幅删减使用特徵数来得重要,本研究提出限制型利基柏拉图基因演算法,透过在基因演算法的挑选过程中,增加一准确率限制的手段,调整基因演算法之搜寻方向,以避免特徵的过度删减,并确保分类准确率的提升。

Therefore, applies dark-field imaging technique to capture images to solve the problem. It is divided into pattern matching and surface defect detection. In the pattern matching, we applied the Blob method to extract the characteristic of the words, and we used Euclidean distance to match the characteristics, recorded the position of the word.

The research of making use of 2D image to form the 3D objects has been a field paid attention to very much all the time. In this work, we propose the synthetic way of a 3D human head, based on image information of multiple-view, cooperate with a Generic 3D head model. By choosing the feature points from images to estimation of position of the camera, and then dealing with information reconstruction of human head and feature point relationship between images and 3D object. Subsequently, applying interpolation technique, the head model is deformed from original model to fit the computed feature points by using Radial Basis Function. Make the form of the head model of people after deformation in conformity with true face of people. Finally, execute 3D head texture mapping and reach the function of translation and rotation with arbitrary direction.
利用二维影像来合成三维物件的研究一直是很受到重视的一个领域,在本论文中,我们提出一个三维立体人头的合成方式,以多张不同视角的影像资讯为基础,配合一个事先准备好的通用三维人头模型(generic 3D head model),透过二维影像中特徵点的选取来估算出拍摄的角度、方位,进而处理人脸模型五官的资讯重塑与特徵点对应的关系,接著利用内差技术,使用放射基底函数对三维通用人头模型作形变,使形变过后人头模型的形状与真实人脸相符,最后对三维通用人头模型作材质贴图,并可对此模型作任意角度、方向的旋转平移,以期达到类似照镜的功能。

The results indicated that most students were dependent on the problem's surface structure for their sortings. Futhermore, an interaction effect was found between the student's grade and their achievement. As the grade level increase, instesad of using surface structure, high achievement students tended to sort problems according to their semantic structure. On the contrary, low achievement students became relied more and more on the surface structure of the problems while sorting.

SABS can be improved by SAFU for Hyperspectral imageries. The proposed SAFU selects the sets of uncorrelated hyperspectral bands for each different class simultaneously while utilizing the inherent separability of different classes in hyperspectral images to reduce dimensionality and further to effectively generate a unique SAFU feature. The experimental results show that the SAFU approach is effective and can be used as an alternative to the existing feature extraction algorithms.
本文提出的SAFU选取不同类别抽取出不同的波段,同时地利用不同类别在高光谱影像中固有的分离性来缩减维度及更进一步地有效产生一个独特的SAFU特徵,最后实验列举了一些分类正确率有不错表现的分类器与PBF分类器进行一些正确率的比较,实验的结果显示SAFU方法是有效且能够被当作目前现有的特徵萃取演算法中的其中一种。
