黑暗的结构大致是视网膜的中心被称为黄斑。渗出物表现为集群的明亮,高对比度的病变,通常是本地化。正常视网膜黄斑有大致对称的圆形区域视神经盘的直径的两倍。使用这个特性,我们可以描述正常和异常情况。为了描述相关的特性,首先获得彩色眼底图像。然后提取圆形区域的利益。小鬼的中间表示被称为运动模式的ROI。小鬼的相关特性推导出对给定图像正常和异常进行分类。
风险的严重程度是基于硬渗出物的位置相对于黄斑的集群。眼底黄斑的面具内最适合圆的中心形象。该地区的圆称为ROI。我表单输入处理的绿色通道。黄斑中心的自动检测。视神经盘可能亮度特征类似于硬渗出物,检测和掩盖。因此产生的图像包含圆形斑块显示黄斑和矩形贴片显示视神经盘。
运动模式的产生是出于生物/计算机视觉系统运动的影响。这些系统代表了一个场景的一组空间抽样强度或一个图像。whwn对象在一个场景在高速移动,它通常留下污点模式捕获的图像。在计算机视觉中,估计和删除涂片模式被称为运动模糊的图像。信号聚集在人眼和相机的传感器位置,产生拖尾效应。我来模拟这种效果,我们诱导运动在一个给定的图像生成的序列图像。运动模式为我是小鬼
莫纳什大学论文代写:黑暗的结构
Dark structure that is roughly at the center of retina is known as macula. Hard exudate appear as clusters of bright ,high contrast lesions and are usually well localized. For normal retina there is a rough symmetry about the macula in the circular region twice the diameter of optic disc. Using this feature we can describe normal and abnormal case. In order to describe the relevant feature, first obtain the color fundus image. Then circular region of interest have been extracted. The intermediate representation of IMP is known as motion of pattern of ROI. Relevant features of IMP is derived to classify the given image as normal and abnormal.
Severity of the risk is based on the location of hard exudate clusters relative to the macula. The best fit circle within the fundus mask with macula at the center of given image. The region with in the circle is known as ROI. The green channel of I form input to all processing. The center of the macula is automatically detected . optic disc may have brightness characteristics similar to hard exudate and it is detected and masked. So the resulting image contain circular patches indicating macula and rectangular patch indicate optic disc.
The generation of motion pattern is motivated by the effect of motion on biological/computer vision system. These system represent a scene as a set of of spatially sampled intensities or an image.. whwn object in a scene moves at a high speed, it usually leaves a smearing pattern in captured image. In computer vision , the estimation and removal of smear pattern is known as motion blur in images. Signal aggregation at sensor location in human eye and camera, give rise to smearing effect. I order to simulate this effect, we induce motion in a given image to generate a sequence of image. A motion pattern for IMP for i is derived as。
