OIF

算法实现消除小面积的区域,保留面积大的区域.对去除小斑点很稳健.(Algorithm to achieve the elimination of small areas of the region to retain the large area of the region. For the removal of small spots very sound.)

使用函数wbmpen获取小波去噪阈值,然后使用函数wbmpen实现信号去噪(Use function wbmpen threshold for wavelet de-noising, and then use the function wbmpen for signal denoising)

一个简单的虚线类，绘制各种虚线的C++类库，请看效果截图，可绘制出各种彩色的虚线效果。画横向或竖向虚线，以及对角线的虚线框效果，都是可以的，带有一个演示程序。(A simple dashed class, draw various dashed C++ library, see the effects shots, you can draw a variety of color dotted effect. Draw horizontal or vertical dashed line, as well as the effect of diagonal dashed box, are possible with a demo program.)

镜片面形数据通过zernike多项式用协方差方法拟合得到的zernike系数(Zernike coefficients covariance fitting)

说明：  hdr图片合成，四幅不同曝光的图片合成一张hdr图片(HDR picture synthesis, four pictures of different exposures synthesize an HDR picture)

利用DCT字典对图形进行稀疏表示，实现两幅图像的融合(Using the DCT dictionary to sparse representation of the graphics to achieve the fusion of two images)

图像阈值分割，基于matlab的二维Renyi熵算法的灰度图像分割(Image threshold segmentation, matlab based two- dimensional Renyi entropy algorithm gray- scale image segmentation)

功能：应用Rudin-Osher-Fatemi模型进行图像去噪，在ROFtest.m 中输入图像，附带文档ROFscheme内容为此模型的数值分析过程，比较详细，适合初学者(Classic 􏰉 Rudin-Osher-Fatemi model denoising, the including documentation is the numerical analysis process of the model in detail, suitable for beginners)

为图像添加各种噪声，如高斯噪声、泊松噪声、椒盐噪声等。（需有openCV）(Add all kinds of noise for the image, such as Gaussian noise, Poisson noise, salt and pepper noise. (The need for openCV))

2014年海康威视校招笔试题，对于想要从事图像处理工作的同学十分有用，图像处理算法类试题，考的是C语言和C++.图像算法类题目不常见。(2014 Hikivision exam)
