Description: 所谓直方图就是在某一灰度级的象素个数占整幅图像的象素比 h=nj/N,其中nj是灰度级在j的象素数，N是总象素数，扫描整幅图像得出的h的离散序列就是图像的直方图，h求和必然＝1，所以直方图可以看成是象素对于灰度的概率分布函数。-Histogram is the so-called gray level in a given number of pixels representing the entire image pixel than h = nj/N, which nj is the gray level of pixels in the j number, N is the total number of pixels, scanning the whole lot images derived from the discrete sequence h is the image histogram, h summation is bound = 1, so the histogram can be viewed as the probability of pixel gray-scale for the distribution function.

Description: 直方圖等化(Histogram Equalization)為一種使用統計方法的影像處理程式設計,它的功能為將統計直方圖的色彩分布平均的打散在直方圖裡,也就是說,讓一張圖的直方圖分布均勻化,同樣的也是使用到LUT(Look-up Table)的方法
而在設計直方圖等化不可或缺的就是需要先知道統計學的機率密度函數(Probability Density Function,PDF)以及累積分配函數(Cumlative Distribution Function,CDF)相關的基本概念,在這邊會簡單的說明機率密度函數及累積分配函數的概念還有直方圖等化的程式設計實作,而OpenCV也提供了直接使用直方圖等化的函式,cvEqualizeHist(),下面就簡單的製作直方圖等化的程式設計
-Histogram equalization (Histogram Equalization) for a use of statistical methods of image processing programming, its function as a statistical histogram of color distribution of the average scatter in the histogram, the words, let the distribution of a histogram graph homogenization, the same also use the LUT (Look-up Table) method
In the design of histogram equalization is an essential need to know the statistical probability density function (Probability Density Function, PDF) and cumulative distribution function (Cumlative Distribution Function, CDF) related to the basic concepts, in the side would be a simple shows probability density function and cumulative distribution function, the concept of histogram equalization programs are designed to implement, while OpenCV also provides direct access to the histogram equalization function, cvEqualizeHist (), Here s the simple production of histogram equalization programming Platform: |

Description: 采用 CAMSHIFT 算法快速跟踪和检测运动目标的 C/C++ 源代码，OPENCV BETA 4.0 版本在其 SAMPLE 中给出了这个例子。算法的简单描述如下-This application demonstrates a fast, simple color tracking algorithm that can be used to track faces, hands . The CAMSHIFT algorithm is a modification of the Meanshift algorithm which is a robust statistical method of finding the mode (top) of a probability distribution. Both CAMSHIFT and Meanshift algorithms exist in the library. While it is a very fast and simple method of tracking, because CAMSHIFT tracks the center and size of the probability distribution of an object, it is only as good as the probability distribution that you produce for the object. Typically the probability distribution is derived from color via a histogram, although it could be produced from correlation, recognition scores or bolstered by frame differencing or motion detection schemes, or joint probabilities of different colors/motions etc.
In this application, we use only the most simplistic approach: A 1-D Hue histogram is sampled from the object in an HSV color space version of the image. To produce the Platform: |

Description: Recently, the problem of automatic traffic accident recognition has appealed to the machine vision community due to its implications on the development of autonomous Intelligent Transportation Systems (ITS). In this paper, a new framework for real-time automated traffic accidents recognition using Histogram of Flow Gradient (HFG) is proposed. This framework performs two major steps. First, HFG-based features are extracted from video shots. Second, logistic regression is employed to develop a model for the probability of occurrence of an accident by fitting data to a logistic curve. In case of occurrence of an accident, the trajectory of vehicle by which the accident was occasioned is determined. Platform: |
