Description: MATLAB中画椭圆的自定义函数：ellipse，用后才会发现这个函数的强大功能！
在ellipse之函数当中，其输入之变数分别如下：
-ra 椭圆之长轴半径，可为列矩阵，若为列矩阵时，代表可同时绘制许多椭圆。
-rb 椭圆之矩轴半径，可为列矩阵，如ra。
-ang 水平轴之倾斜角，以弧度表示。可为列矩阵，但ra、rb、ang三者之矩阵数应相同。
-x0,y0 圆心之座标，可为矩阵，若为矩阵时，代表可同时绘制许多不同圆心位置之椭圆。
-C 椭圆线之颜色

确。-Distributed satellites (DS) moving in low earth orbit is suffered from the influence of atmospheric perturbation ,
and the orbit configuration of the DS is destroyed soon. The center of the relative orbit of the circling satellite is drifting
continuously. This study was conducted to establish a compensatory approach to reduce the influence of atmospheric perturbation on
the orbit configuration of the DS. Thus , the orbit configuration can be maintained naturally better. In the study , based on the
atmospheric density model considering the effect of altitude change and diurnal variation of solar radiation , the semi- major axis
perturbation equation of circling satellite with different initial phase in the DS is deduced. A semi- major axis modified method is
presented to compensate the influence of atmospheric perturbation. It is shown from the simulation that the influence of the
atmospheric perturbation can be decreased greatly in a given time period using this modified method

Description: 细胞分类器 pami的论文实现，不错的代码-Cells were segmented using a custom-made image processing pipeline. The segmentation pipeline was implemented in order to distinguish cells from the background. The segmentation pipeline is composed of standard image-processing operations in the following order: 1, original image 2, Sobel edge detection 3, image dilation 4, removal of objects close to image borders 5, image erosion 6, removal of small objects 7, filling of gaps inside the cell and 8, overlay of the final result on the original image.
Seven morphological features were extracted from each of the segmented cells. The feature space in which we performed statistical classification was therefore seven-dimensional (7D one vector for each cell), with the following features: area, major and minor axis lengths, perimeter, eccentricity, extent, and number of fingers (Gorelick, PAMI, 2006). Statistical analysis was performed on the 7D feature vectors, using a tree-like classification method called the ’node harvest’ meth

Description: The code is reasonably fast due to (optional) randomization and full code vectorization. However, as the algorithm needs to compute pairwise point distances, it can be quite memory intensive. If you get out of memory errors, either downsample the input image or somehow decrease the number of non-zero points in it. It can deal with big amount of noise but can have severe problem with occlusions (major axis end points need to be visible)

A new auricle major axis labeling method is proposed. According to the long axis of the outer ear will ear into a unified standard size and angle using active shape model algorithm, the realization of the automatic search of the outer ear contour and the algorithm was improved to adjust the initial position of the model. The experimental results show that the improved active shape model (ASM) can converge more quickly and accurately, and the normalization method is able to provide the guarantee for the subsequent feature recognition.
