[图形图像处理] OpenCV_CalcHist

直方图是计算机视觉中一个很重要的工具,OpenCV里面提供了不少有关直方图处理的函数。其中最基本的是计算直方图的函数calcHist()。有关直方图在前面的博文中也有所介绍:基础学习笔记之opencv(4):直方图使用学习。不过目前由于本人课题研究上需要计算多张图片的一维直方图特性,且每张图片对应有自己不同的掩膜矩阵,开始以为OpenCV中提供的calcHist()函数能够实现这个功能,因为其中一个重载函数中有一个参数为InputArrayOfArrays,咋一看会觉得这不就是可以处理多张图片的吗?后面仔细研究后发现其实它实现的功能和我的需求是不同的,因此需要自己单独写函数来完成这一功能。 开发环境:OpenCV2.4.3+Qtcreator2.5.1
The histogram is a very important tool in computer vision, OpenCV which provides a lot of information on the function of the histogram processing. One of the most basic is calculated histogram function calcHist (). The histogram has also been introduced in front of the Bowen: basic study notes of opencv (4): histogram learning. However, I research needs to be calculated multiple pictures of a one-dimensional histogram characteristics, and each image corresponds to a different mask matrix, and began to think that OpenCV provided calcHist () function to enable this functionality, because one of the a parameter InputArrayOfArrays, at first glance Is not that can handle multiple pictures you will feel overloaded functions? Behind careful study to find out that it implements the functionality and my needs are different, and therefore requires its own separate write a function to accomplish this function.

[图形图像处理] Qt_RobHess_Sift

sift算法在cv领域的重要性不言而喻,该作者的文章引用率在cv界是number1.本篇博客只是本人把sift算法知识点整理了下,以免忘记。本文比较早的一篇博文opencv源码解析之(3):特征点检查前言1 中有使用opencv自带的sift做了个简单的实验,而这次主要是利用Rob Hess的sift源码来做实验,其实现在的opencv版本中带的sift算法也是Rob Hess的,只是稍微包装了下。 下面来做下试验,试验sift代码采用Rob Hess的代码,opencv目前版本中的sift源码也是采用Rob Hess的。代码可以在他的主页上下载:http://blogs.oregonstate.edu/hess/code/sift/ 这里我下载的是windows版本的,并采用Qt做了个简单的界面。
sift algorithm is self-evident the importance of the cv field, the author of the article referenced in the cv sector is number1 this blog I just sift algorithm knowledge compiled under, so as not to forget. This article compares the earlier blog post opencv source code analysis (3): check the preface of the feature points 1 the opencv bring their own sift to do a simple experiment, but this time Rob Hess' s sift source to experiment. In fact, with the opencv version sift algorithm is Rob Hess, only slightly packing the next. Below to do the next test, test sift code using the code of Rob Hess, sift source opencv version of Rob Hess. The code can be downloaded on his home page: http://blogs.oregonstate.edu/hess/code/sift/ here I downloaded the windows version, and using Qt to do a simple interface.

[图形图像处理] An_Intrgrated_De-interlacing_Algorithm_Design

本篇論文提出的整合式解交錯(Integrated De-interlacing)的演算法,可以有效提昇移 動區域的畫面,但是當移動估計不正確時,反而會使移動補償後的畫面變得很差,為了 改善這種情況,因此結合移動可適性解交錯的優點,並將空間圖場內插(Spatial Interpolation)的方式改成ELA(Edge Line Average)來設計,經過電腦模擬的結果發現,不僅在視覺上提高畫面的解析度,在某些影像峰值訊號雜訊比(Peak Signal Noise Ratio , PSNR)也比線平均解交 錯(Line Average De-interlacing)多出好幾分貝的畫質增益。 此外,在整合式解交錯演算法中也增加影片偵測(Film Detection)和影像加強(Image Enhancement)的演算法設計,在這樣演算法的架構下,透過影片偵測的演算法,我們可 真實地還原3:2 Pull Down 的影片格式,而不會有鋸齒狀(Saw-Toothed)的畫面出現,而影 像加強的演算法,則可以在解交錯後,經過影像的調整,使輸出畫面呈現不同的效果, 達到消費者的需求。
The main theme of this thesis is an integrated de-interlacing system, which incorporates several known and improved techniques in a nice manner to produce good de-interlaced image quality. We first develop an accurate motion detector that classifies image regions into stationary, low-motion, and high-motion categories. The simple field merging method is applied to the stationary regions. The edge line average interpolation method is applied to the slow-motion regions. Finally, the motion-compensated interpolation is applied to the high-motion regions. In addition, hierarchical motion estimation and motion vector smoothing techniques are employed to enhance the quality of estimated motion vectors. Our computer simulation shows that the subjective image quality is improved by using the proposed scheme. Also, its PSNR measures are better than the conventional spatial or temporal interpolation schemes. (2010-10-26, PDF, 1144KB, 下载10次)
