Image mirroring is one of the basic geometric transformations of the image, it is also very simple to implement, first paste the source code:
#include
The image mirroring function mainly uses the remap () function in OpenCV, which is prototyped as follows:

Very Deep convolutional Networks for large-scale Image Recognitionkaren Simonyan, Andrew ZissermanIn this work we investigate the effect of the convolutional network depth on its accuracy in the large-scale image Recogni tion setting. Our main contribution are a thorough evaluation of networks of increasing depth, which shows that a significant improvement On the Prior-art configurations can is achieved by

The rotation of the picture is essentially the position of the original image for each pixel in the rotated picture. And then copy it over.(In other words, if the position calculated in the original image is not an integer but a decimal, because the number of pixels is an integer, a decimal-to-integer conversion is required.) This conversion process is fastidious and requires interpolation: nearest neighbor

Preface
Image pyramid is a very important concept in computer graphics.
This article will introduce this concept in detail and its implementation and application.
Definition of image pyramid
An image pyramid is a collection of images. All images in a set are a sequence of images obtained by downsampling a specific image

Calculate the hash value: Combining the results of the previous step, together, constitutes a 64-bit integer, which is the fingerprint of this image. The order of the combinations is not important, just ensure that all images are in the same order;6. After getting the fingerprint, you can compare different images and see how many of th
