问题 I want to use template matching, i am utilizing a code that i found that does what i want where it keeps it in bitmap and get a return of bitmap, the problem is im not entirely sure how i can get to drawing in the rectangles. I am using only java, no native while creating an app for android. With the use of openCV which i am new at. I will get multiple matches so i would like to get drawn rectangles around those point and also be able to obtain a value for the locations of these matches.

Match 2 lists of strings by ressemblance

由 断了今生、忘了曾经 提交于 2019-12-07 17:33:36
问题 Problem I have 2 lists of strings. I want to find the best matching pairs from my lists. For example, I have those 2 lists: list1 = {"a1","b1","c1"} list2 = {"a2","b2","c2"} I want to get the following results: results = {{"a1,"a2"}, {"b1,"b2"}, {"c1,"c2"}} Additional Info To compare 2 strings together, I would like to use something similar to the Levenshtein distance. For example, when I compare "a1" with "a2" , it gives me a shorter distance than "a1" with "b2" , so "a1" + "a2" would be

How to perform complex multicolumn match in R /

由 一曲冷凌霜 提交于 2019-12-07 09:40:15
问题 I wish to match two dataframes based on conditionals on more than one column but cannot figure out how. So if there are my data sets: df1 <- data.frame(lower=c(0,5,10,15,20), upper=c(4,9,14,19,24), x=c(12,45,67,89,10)) df2 <- data.frame(age=c(12, 14, 5, 2, 9, 19, 22, 18, 23)) I wish to match age from df2 that falls into the range between lower and upper in df1 with the aim to add an extra column to df2 containing the value of x in df1 where age lies between upper and lower. i.e. I want df2 to

Prefix vs Suffix Trie in String Matching

由 喜欢而已 提交于 2019-12-07 09:30:20
问题 I'm not too well-versed about the actual algorithms used in string matching with tries. I'm wondering why there seems to be more focus on suffix tries for string matching rather than prefix tries. Can we not use prefix tries for substring matching also? Put in another way, what are the advantages of suffix tries over prefix tries? 回答1: .retteb era seirt xiferp ,drawkcab daer uoy fI Seriously. Suffix tries allow you to traverse from the beginning of a string. 来源： https://stackoverflow.com

ANTLR: how to parse a region within matching brackets with a lexer

由 别来无恙 提交于 2019-12-07 09:00:42
问题 i want to parse something like this in my lexer: ( begin expression ) where expressions are also surrounded by brackets. it isn't important what is in the expression, i just want to have all what's between the (begin and the matching ) as a token. an example would be: (begin (define x (+ 1 2))) so the text of the token should be (define x (+ 1 2))) something like PROGRAM : LPAREN BEGIN .* RPAREN; does (obviously) not work because as soon as he sees a ")", he thinks the rule is over, but i

Maximum bipartite graph (1,n) “matching”

由 佐手、 提交于 2019-12-07 08:30:55
问题 I have a bipartite graph. I am looking for a maximum (1,n) "matching", which means that each vertex from partitation A has n associated vertices from partition B. The following figure shows a maximum (1,3) matching in a graph. Edges selected for the matching are red and unselected edges are black. See figure http://www.freeimagehosting.net/uploads/9a8df2d97c.gif This differs from the standard bipartite matching problem where each vertex is associate with only one other vertex, which could be

XSLT 2.0 - Template Matching With Contains()

由 五迷三道 提交于 2019-12-07 05:07:55
问题 I'm wondering if it is possible to write a template match with the contains() function. I have a document that has multiple elements that need to be renamed to a common element. All of the following need to be renamed to just OP: OP1.2, OP7.3, OP2.4, OP5.6`, etc. 回答1: Yes, you can use contains() inside of a predicate filter in the match criteria for elements. <xsl:template match="*[contains(local-name(),'OP')]> <OP> <xsl:apply-templates select="@*|node()"/> </OP> </xsl:template> You could

How do I match similar coordinates using Python?

由 懵懂的女人 提交于 2019-12-07 05:02:36
问题 Background: I have been given four catalogues of data, the first of which (let's call Cat1) gives the coordinates (in right ascension and declination, RA and Dec) for radio sources in fields 1 and 2, the second catalogue (Cat2) gives the RA and Dec for radio sources and infrared (IR) sources in field 1, the third catalogue (Cat3) gives the RA and Dec for radio and IR sources in field 2, and the fourth catalogue (Cat4) gives the RA and Dec for optical sources in fields 1 and 2. Cat1 has

问题 I developed the following API for semantic matching for sentences using ws4j library. But im failing to get the semantic similarities. The ouptut is attached as an image which shows values which are redundant or 0. Is there any library which is missed out to be called? package ws4jv01; import edu.cmu.lti.lexical_db.ILexicalDatabase; import edu.cmu.lti.lexical_db.NictWordNet; import edu.cmu.lti.ws4j.RelatednessCalculator; import edu.cmu.lti.ws4j.impl.HirstStOnge; import edu.cmu.lti.ws4j.impl
