preface Digital image processing c++ opencv (VS2019 opencv4.53) is continuously updated 1, Homomorphic filtering principle 1. Treatment principle (1) It is considered that the image f(x,y) consists of two parts: illumination component i(x,y), reflection component r(x,y): f ...

SeetaFace2 Android platform compilation Project address: https://github.com/seetafaceengine/SeetaFace2 SeetaFace2 face recognition engine includes three core modules required to build a full-automatic face recognition system, namely: face detection module FaceDetector, face key point positioning module facelandmark and face feature extraction ...

edge detection 1, Understanding of edge detection Edge generally refers to the region where the intensity of an image changes sharply in a certain part. There are generally two situations of strength change: Step change: The image value changes from low to high, and the image changes from dark to bright Peak change: From dark to light ...

1. Preparatory knowledge 1.1 filtering, kernel and convolution The filter is an algorithm for calculating a new image I '(x,y) from an image I(x,y) according to the region near the pixel x,y. The template specifies the shape of the filter and the composition law of the values of pixels in this area, also known as "filter" or &qu ...
