OpenCV+OpenCvSharp implements image feature vector extraction and similarity calculation
The image feature vector is a mathematical representation used to describe the content of the image. It can reflect the color, texture, shape and other information of the image. Image feature vectors can be used to do many things, such as image retrieval, classification, recognition, etc. This article will introduce the extraction of image feature […]

Extraction and constexpr
I recently reviewed the extraction and found that it is similar to constexpr. The records are as follows. 1. Extraction extraction The central idea of STL is to separate the container and the algorithm, and then glue the two together through the iterator. Performing algorithm calculations through iterators requires two issues: Question 1. Different algorithm […]
Matlab implements image filtering, edge extraction (five operators), and sharpening (two gradient operators)
1. Experiment purpose 1. Image 3*3 mean filtering and median filtering. 2. Use gradient, sobel, and Laplacian operators to sharpen the image. 3. Use multiple operators (at least five) to extract edges from the image. Compare the characteristics of each operator, analyze the processing results, find out where in the image the processing effect is […]
