The following, is a possible implementation in the Python language: def balanced_histogram_thresholding ( histogram , minimum_bin_count : int = 5 , jump : int = 1 ) -> int : """ Determines an optimal threshold by balancing the histogram of an image, focusing on significant histogram bins to segment the image into two parts.
A v-optimal histogram is based on the concept of minimizing a quantity which is called the weighted variance in this context. [1] This is defined as = =, where the histogram consists of J bins or buckets, n j is the number of items contained in the jth bin and where V j is the variance between the values associated with the items in the jth bin.
In addition, the choice of appropriate statistical graphics can provide a convincing means of communicating the underlying message that is present in the data to others. [1] Graphical statistical methods have four objectives: [2] The exploration of the content of a data set; The use to find structure in data; Checking assumptions in statistical ...
In robotics, Vector Field Histogram (VFH) is a real time motion planning algorithm proposed by Johann Borenstein and Yoram Koren in 1991. [1] The VFH utilizes a statistical representation of the robot's environment through the so-called histogram grid, and therefore places great emphasis on dealing with uncertainty from sensor and modeling errors.
The data used to construct a histogram are generated via a function m i that counts the number of observations that fall into each of the disjoint categories (known as bins). Thus, if we let n be the total number of observations and k be the total number of bins, the histogram data m i meet the following conditions:
The goal of density estimation is to take a finite sample of data and to make inferences about the underlying probability density function everywhere, including where no data are observed. In kernel density estimation, the contribution of each data point is smoothed out from a single point into a region of space surrounding it.
The life-and-death implications of data can be highly technical and hard to convey. But looking at the kinds of data being erased, a clear narrative of political intent emerges. In 2017, Immigration and Customs Enforcement stopped publishing routine data about its enforcement raids, and it no longer updates the list of deaths occurring in its ...
The relation between the quality of a data mining system and the amount of investment that the decision maker is willing to make was formalized by providing an economic perspective on the value of “extracted knowledge” in terms of its payoff to the organization [8] This decision-theoretic classification framework [8] was applied to a real ...
