Article Introduction：User-defined classes are also one of the necessary conditions for learning PHP well. Classes in PHP are relatively simple compared to classes in other object-oriented languages. PHP only has classes, methods, attributes, single inheritance (extensions), etc. In PHP, it is very simple to create a class. You only need the keyword class. The definition of the simplest class is as follows:

Article Introduction：What I want to talk about here is the hover effect of a menu. Generally, the menu switching we implement through the CSS pseudo-class:hover is relatively monotonous, because it is just a simple picture change, unlike many flash menus that change very smoothly. But here we are going to use non-flash technology to achieve a smooth hover effect.

Article Introduction：Computing similarity between images is an open problem in computer vision. Today, when image generation is popular all over the world, how to define "similarity" is also a key issue in evaluating the authenticity of generated images. Although there are some relatively straightforward methods to calculate image similarity, such as measuring the difference in pixels (such as FSIM, SSIM), the similarity difference obtained by this method is far from the difference perceived by the human eye. After the rise of deep learning, some researchers found that the intermediate representations obtained by some neural network classifiers, such as AlexNet, VGG, SqueezeNet, etc., after training on ImageNet, can be used for the calculation of perceptual similarity. In other words, embedding is closer to people than pixels. For multiple pictures

Article Introduction：Use PHP and coreseek to implement intelligent image search function Summary: This article will introduce how to use PHP and coreseek open source search engine library to implement intelligent image search function. Through feature extraction and similarity comparison of images, we can quickly find similar images in a large number of images. In addition, we will also use the full-text search function of coreseek to realize the function of searching pictures based on keywords. Keywords: PHP, coreseek, image search, feature extraction, phase

Article Introduction：In PHP, matching two dates goes very smoothly when they have similar formats, but when two dates have unrelated formats, PHP fails to parse. In this article, we will discuss the different scenarios of date comparison in PHP. We will find out how to compare dates using the DateTime class and strtotime() function. Case 1: If the given dates have similar format, we can analyze these dates through simple comparison operators. <?php$date1="2018-11-24";$date2="2019-03-26";if($date1>$date2)ech

Article Introduction：C language and PHP are two different types of programming languages, representing compiled languages ​​and interpreted languages ​​respectively. Although they are very different in syntax and usage, there are some similarities in some aspects. This article will delve into the similarities and differences between C language and PHP, and demonstrate the differences and connections between them through specific code examples. First, let's start the comparison with a simple &quot;HelloWorld&quot; program. In C, a simple &quot;HelloWorld&quot; program looks like this: #inclu

Article Introduction：Introduction In the field of computer vision, accurately measuring image similarity is a critical task with a wide range of practical applications. From image search engines to facial recognition systems and content-based recommendation systems, the ability to effectively compare and find similar images is important. The Siamese network combined with contrastive loss provides a powerful framework for learning image similarity in a data-driven manner. In this blog post, we will dive into the details of Siamese networks, explore the concept of contrastive loss, and explore how these two components work together to create an effective image similarity model. First, the Siamese network consists of two identical subnetworks that share the same weights and parameters. Each sub-network encodes the input image into a feature vector, which
