how does Flann Matcher train work in opencv?

会有一股神秘感。 提交于 2019-12-25 02:48:45
问题 I'm new in opencv. My question is: I have 2 train image descriptor trainA and trainB. Then i construct a vector to put them in, and add them into flann matcher for train. After that, i use query image descriptor queryC to do the knnMatch and get a DMatchs returned. In this case, which train descriptor would be used to match queryC, trainA or trainB? and how does the training help to improve the match accuracy? Thanks in advance. 回答1: Both. It is not "training" in standard meaning. "Training"

问题 Possible duplicate: RegEx matching HTML tags and extracting text I need to get the text between the html tag like <p></p> or whatever. My pattern is this Pattern pText = Pattern.compile(">([^>|^<]*?)<"); Anyone knows some better pattern, because this one its not very usefull. I need it to get for index the content from web page. Thanks 回答1: SO is about to descend on you. But let me be the first to say, don't use regular expressions to parse HTML. Here is a list of Java HTML Parsers. Look

Verifying that a Regular Expression Matches

感情迁移 提交于 2019-12-24 17:55:00
问题 I have a regex that, according to what I can tell and to what RegexPal says, does not match the full string I am testing (only its rightmost part). However, matcher.matches() returns true! So, what is the most reliable way to determine whether a java.util.regex Matcher actually fully matches a string? Also, suppose that one wants to use matcher.find() as follows: if (a match was found) { while (matcher.find()) { // Do whatever } ] Is there any way of implementing the "a match was found"

问题 I am trying to use org.hamcrest.Matchers.contains(java.util.List<Matcher<? super E>>), but the compiler tells me that it cannot resolve the method. I even tried the example given by Hamcrest here, but I get the same compilation error: assertThat(Arrays.asList("foo", "bar"), contains(Arrays.asList(equalTo("foo"), equalTo("bar")))); Error:(13, 9) java: no suitable method found for assertThat(java.util.List<java.lang.String>,org.hamcrest.Matcher<java.lang.Iterable<? extends java.util.List<org

问题 I have seen that there are some posts regarding the Java Matcher class, but I was not able to find one regarding the specific methods find() and group() . I have this piece of code, where Lane and IllegalLaneException have already been defined: private int getIdFromLane(Lane lane) throws IllegalLaneException { Matcher m = pattern.matcher(lane.getID()); if (m.find()) { return Integer.parseInt(m.group()); } else { throw new IllegalLaneException(); } } Looking at the Java Documentation, we have

问题 I want to run this line of code: assertThat(contextPin.get(), equalTo(pinPage.getPinObjFromUi())); but I want to print to the log be informative meaning that I could know which fields were not equal. So I have thought to implement a matcher. I have googled it, but couldn't write it properly as my method couldn't get the actual and expected objects together. here is my code: how can I write it clean? public class PinMatcher extends TypeSafeMatcher<Pin> { private Pin actual; private Object item

Using Matcher to extract URL domain name

问题 static String AdrPattern="http://www.([^&]+)\\.com\\.*"; static Pattern WebUrlPattern = Pattern.compile (AdrPattern); static Matcher WebUrlMatcher; WebUrlMatcher = WebUrlPattern.matcher ("keyword"); if(WebUrlMatcher.matches()) String extractedPath = WebUrlMatcher.group (1); Considering above codes, My aim is to extract the domain name from the URL and dismiss the rest. But the trouble is that, first of all, if the URL has deeper path, it will not ignore it and second, it does not work for all
