But these methods limited by the expense of computing fundamental matrices and trifocal tensors or of the nonlinear optimization involved in computing epipolar tangencies. Through the studies of the invariants of the single axis motions, computational theories have been developed in this thesis to provide practical solutions for the problem of structure and motion from fitting the corresponding points in the whole sequence to its conic locus or conics for short.
在最近的研究中,一些研究人员利用视觉几何的方法从非定标的图象中对单轴旋转运动进行分析,提出了利用基本矩阵和三焦距张量求解单轴旋转运动中的关键参数——旋转角度的算法,但是该算法需要计算一系列相邻2图象的基本矩阵和一系列相邻3图象的三焦距张量,由于每个基本矩阵的自由度为7,每个三焦距张量的自由度为18,导致算法参数数量非常之大。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.
在证明了理想滤波器的不可实现性之后,得知通过选择适当的窗函数可获得很好的滤波函数,经过两个实际滤波器的效果对比,我们选取了较好的"巴拿马帽"形滤波函数,同时也介绍了一个有效的提高重建质量的线性内插函数,概要地叙述了平行射束图象重建的计算机具体实现步骤后,对几个物体的模拟投影数据进行了重建:投影角为180°,每视角下有100个平行投影数据点,在386微机上重建尺寸为64×64,时间约为40秒;在486/33MHz微机上只用了12秒,图象的象点精度是0.31mm。

In this thesis, the theories and methods of GA are analyzed in detail , the trend of GA in recent times is briefly discussed. Because of the importance of image segmentation, two methods of color image segmentation based on GA are proposed. One is the surface of thresholds image segment method, the other is entropic threshold method. Two algorithms are realized through VC++ 6.0. After that, we compare the characteristics of two algorithms and prove that GA can be very well applied to solving image optimal problems.
