OpenCV13-Image noise: salt-and-pepper noise and Gaussian noise 1.Types of noise 2. Salt and pepper noise 3. Gaussian noise 1. Types of noise Image noise refers to random or non-random unwanted visual disturbances in images. It can appear in digital images in various forms such as grainy noise, streaks, spots, blur, distortion, etc. Image noise may […]

java js longitude and latitude conversion, geodetic coordinates (Gaussian projection coordinates) and longitude and latitude conversion to each other
In the project, there is a need to convert between geodetic coordinates (Gaussian projection coordinates) and longitude and latitude. I wrote a tool class; There are java and js codes As shown in the figure, the coordinate system and bandwidth have been passed into the method as parameters in the java code. When using it, […]
[Transfer] [Gaussian] Gaussian fuzzy algorithm [2]
Two years ago, I published an article: C++ Gaussian Blur Algorithm Example under Win32, which gave an implementation of Gaussian Blur and wrote a rough introduction. However, the content was very simple at that time, and the accompanying example algorithm was flawed: First, the corners of the image are processed by “skipping”, resulting in black […]
[Image Fusion] Gaussian of Difference: A simple and effective universal image fusion method [used to fuse infrared and visible light images, multi-focus images, multi-modal medical images and multi-exposure images] (Matlab code implementation)

What sparks will emerge from the collision between neural networks and Gaussian processes?
Source: Algorithm Advanced This article is about 2,000 words, and it is recommended to read it for 5 minutes. In this article, we first sort out the relationship between single hidden layer neural networks and Gaussian processes (GP), then expand the concept to multi-hidden layer neural networks, and then discuss how to use GP to […]
Gaussian column pivot elimination method to solve linear equations and its implementation in C language
We have learned three methods for solving linear equations in linear algebra or advanced algebra: Crammer’s rule, matrix transformation and inversion matrix, and Gaussian elimination method. However, when computers are used to perform corresponding engineering calculations, the number of equations they calculate is often very large, resulting in a very large amount of calculations for […]

opencv – resize, pyrUp and pyrDown image pyramid (Gaussian pyramid, Laplacian pyramid) and size scaling (upsampling, downsampling)…
We often convert images of a certain size into images of other sizes. If we need to enlarge or reduce the size of the image, we can use the following two methods in OpenCV: resize function, the most direct method. The pyrUp and pyrDown functions, two functions related to the image pyramid, perform upsampling and […]
