dirty glass
建立一个透明物体上有污点的模型,可以模拟玻璃上有污点的图象(Rendering of clean transparent objects has been well studied in computer graphics. However, real-world transparent
objects are seldom clean—their surfaces have a variety of contaminants such as dust, dirt, and lipids. These
contaminants produce a number of complex volumetric scattering effects that must be taken into account when
creating photorealistic renderings. In this paper, we take a step toward modeling and rendering these effects. We
make the assumption that the contaminant is an optically thin layer and construct an analytic model following
results in radiative transport theory and computer graphics. Moreover, the spatial textures created by the different
types of contamination are also important in achieving visual realism. To this end, we measure the spatially
varying thicknesses and the scattering parameters of a number of glass panes with various types of dust, dirt, and
lipids. We also develop a simple interactive synthesis tool to create novel instances of the me)

精通Matlab数字图像处理与识别
数字图像处理(Digital Image Processing)是通过计算机对图像进行去除噪声、增强、复原、分割、提取特征等处理的方法和技术。 [1] 数字图像处理的产生和迅速发展主要受三个因素的影响:一是计算机的发展;二是数学的发展(特别是离散数学理论的创立和完善);三是广泛的农牧业、林业、环境、军事、工业和医学等方面的应用需求的增长(Digital Image Processing (DIP) is a method and technology of removing noise, enhancing, restoring, segmenting and extracting features from images by computer. [1] The emergence and rapid development of digital image processing are mainly influenced by three factors: first, the development of computer; second, the development of mathematics (especially the establishment and improvement of discrete mathematics theory); third, the growth of the demand for extensive applications in agriculture, animal husbandry, forestry, environment, military, industry and medicine.)

PicMatch
本程序实现了对影像特征点自动提取,利用Morevac、Forstner、Harris3个经典算子。在此基础上利用相关系数法实现影像自动匹配,并且引入最小二乘平差,使匹配点精度有所提高。
在搜索点过程中,利用了核线影像特性,对二维影像搜索使用了爬山法启发式搜索。对大数据量影像采用影像金字塔结构处理。
1、使用GDAL库读取影片,支持TIFF、PNG、JPEG、JPG、BMP、GIF、IMG格式读取。使用GDI绘图。
2、防止大数据量绘图视图闪烁,图片显示采用双缓存技术。
3、保存视图数据为图片文件,支持TIFF、PNG、JPEG、JPG、BMP、GIF格式保存。
4、TreeCtrl控件、ListCtrl控件的基本操作。
5、MFC单文档程序视图通讯、更换视图、视图分割。(This program of image features automatic extraction point, use Morevac, Forstner, Harris3 a classic operator. Based on the correlation coefficient method using the image matching, realization and introducing least squares adjustment, the matching point to improve precision.
In the search process, the use of the image characteristics of nuclear line, 2d image search using the heuristic method of climbing. For large quantity of data using image processing image pyramid structure.
1, using film, read GDAL repository support JPEG, TIFF, PNG, GIF, BMP, JPG, read IMG format. Use GDI drawing.
2 and prevent large amount of data, drawing view pictures showed adopt double caching techniques.
3, save for the image file, views data support JPEG, TIFF, JPG, PNG, GIF, BMP format.
4 and TreeCtrl controls, the basic operation ListCtrl controls.
5 and MFC single document procedure view communication, replace view, view.)
