Exclusive and original! The sparrow optimization algorithm that combines northern goshawk and adaptive t distribution has excellent results! Highly recommended product! MATLAB code…

Statement: Resale and reselling of the author’s original code is prohibited, and violators will be prosecuted! The sparrow search algorithm (SSA) was proposed in 2020 and has been widely used in many fields. The design of the Sparrow algorithm is inspired by the biological characteristics of birds. The mathematical model established based on the foraging […]

Implementation steps of MATLAB panorama cutting and box plot display

Reference: Implementation steps of MATLAB panoramic cutting and box plot display | w3cschool notes In the field of photography, panorama is a photography technology that can capture all the surrounding 360-degree scenes, but the actual look and feel of panorama is not that good (see the example of panorama below). We can use matlab to […]

Talking about “360 panoramic stitching” of fisheye camera from open source projects

Table of Contents Overview Let’s start from the background of 360 panorama Talk about perspective changes across parameter calibration Post-processing of spliced pictures references Overview The reason for writing this article stems entirely from open source projects (see reference 1 for GitHub). This project covers a relatively complete production process of the surround view system, […]

(STL hash) unordered_map

1. unordered series containers In C++98, STL provides a series of associative containers with red-black tree structures at the bottom, including set, multiset, map and multimap. The time complexity of query operations for these containers is O ( log N ) O(logN)O(logN), where N is the number of elements in the container. In order to […]

How does the front end prevent data from being abnormally tampered with and restore the data?

Every day, we deal with various documents, such as PRD, technical solutions, personal notes, etc. In fact, there is a lot of knowledge in document formatting. Just like me, I have obsessive-compulsive disorder about formatting, and I can’t bear to not add spaces between English and Chinese. Therefore, I have recently been working on a […]
