face recognition using java

This article describes the Java implementation based on histogram application of similar image recognition, is a very practical skill. Share to everyone for your reference. The specific analysis is as follows: An overview of the algorithm: Firstly, the histogram data is collected from the source image and the image to be screened, the histogram of each image is normalized and then the histogram is compute

estimate the number of elements stored, we can set the initial capacity to avoid recalculation of hash values or expansion. For type safety, the reason for readability and robustness is always to use generics. Also, using generics avoids classcastexception at run time. Using the invariant Class (immutable Class) provided by the JDK as the key to the map avoids implementing the hashcode () and Equal

is inherited from Collection,map not.Swtich whether it can function on a byte, can it function on a Long, and can it function on a string? Swtich can only be used in byte short int char can a Chinese character be stored in a char variable? Can be defined as a Chinese, because in Java encoding in Unicode, a char accounted for 16 bytes, so put a Chinese is no problem . There are several ways to implement multithreading, what is it? What is the

using iterators, other threads modify the map, then the concurrentmodificationexception is thrown, which is the so-called Fail-fast Mechanism. The implementation of this mechanism in the source code is through the Modcount domain, Modcount as the name implies is the number of changes, the HashMap content will increase this value, then in the iterator initialization process will assign this value to the expectedmodcount of the Iterator. In the iterati

How the cluster synchronizes session state4, the principle of load balancing5, if there is a particularly large amount of traffic, to the database, how to do optimization (db design, dbio,sql optimization,

In this article we are going to discuss the different types of face questions in a Java interview, which allow employers to test the candidate's Java and common object-oriented programming capabilities. The following sections are divided into two chapters, the first of which will discuss object-oriented programming and its features, common questions about
